15 ‰, polypropylene fibre 0.1-2 ‰, hydrophober 0.5-5 ‰, polyvinyl alcohol 0-3 ‰, adhesive 1-3 ‰, air entraining agent 0.5-
0.7‰。
Above-mentioned inner wall of building lightweight plastering gupsum, the water-retaining agent are cellulose ether.
Above-mentioned inner wall of building lightweight plastering gupsum, operable time >=60min of the lightweight plastering gupsum, presetting period >=
The MPa of the MPa of 75min, water retention >=75%, flexural strength >=1.0, compression strength >=2.5, shear bonding strength >=0.3
MPa, bulk density≤800kg/m3 。
Beneficial effects of the present invention are：
（ 1 ）Environmentally protective, production and use are without any pollution, nontoxic, radiationless, with good breathing and gas permeability
Can, certain capillary is formed after lightweight plastering gupsum aquation, has the function of certain suction humidity.Indoor air humidity can be adjusted,
Energy ant prevention bite and corrosion etc.；Belong to A grades of fire proofing materials, good thermal insulation separation is made it have because being added to light-weight aggregate perlite wherein
Heat, sound insulation, fire resistance.
（ 2 ）Cohesive force is strong, not easily to fall off, and shrinkage is small, overcomes hollowing, cracking that traditional cement mortar often occurs
Phenomenon.Aerated concrete wall shrinking percentage general control is 0.4 ‰~0.6 ‰；And the coat of plaster shrinking percentage of lightweight plastering gupsum
≤ 0.6 ‰,（General cement mortar rendering layer shrinking percentage≤3 ‰）, shrinking percentage is close to be not likely to produce hollowing cracking.
（ 3 ）Workability is good, not bleeding, do not isolate, easy for construction, directly plus water uses, and process is easy, and it is few to land ash,
It is swift to operate.Operable time is long, can adjust the addition of coagulating agent as needed to control setting time.
（ 4 ）It can guarantee and smear for strong walls of water absorbing forces such as air entrained concrete with good water-retaining property and workability
Hydration reaction is complete after ash, and coat of plaster intensity will not be reduced because of dehydration.For various metopes, such as concrete, air entrained concrete
It is not necessarily to carry out interface processing Deng, can be used directly, effectively save engineering cost.
（ 5 ）The duration is saved, lightweight scratch coat gypsum can be survived once, and because its gain in strength is fast, be easy drying, can
Many processes are saved, are accelerated construction progress, the engineering that plastered work amount is big, the duration is tight is suitble to.Lightweight plastering gupsum is in aquation mistake
Cheng Zhong is mainly generated in network structure dihydrate gypsum crystal, these crystal are with Free water in simultaneously network structure within a short period of time
It is constantly siphoned away by aerated concrete wall, slurry loses flowability and condenses, mixed with aerating to generate higher-strength quickly
The porous structure cooperation of solidifying cob wall body, generates good integral strength.
Specific implementation mode
This inner wall of building lightweight plastering gupsum of the present invention is obtained by the dihydrate gypsum that building gypsum aquation is formed, multiple
Close hydrated calcium silicate, drated calcium aluminate gel and entringite (3CaO that mineral admixture generates during hydration reaction
Al2O33CaSO432H2O), they are dispersed in around dihydrate gypsum crystal generates cladding protective effect to dihydrate gypsum, makes
Lightweight plastering gupsum plastering hardenite later strength and water resistance are improved.Lightweight plastering gupsum has good operation
Property, water-retaining property, the materials for wall of unlike material, absorption speed are variant with water absorption rate.
To ensure that lightweight plastering gupsum float coat there are enough hydration times, prevent dehydration is too fast from causing cracking, picking, with
And improve the workability of lightweight plastering gupsum construction and bond the sagging resistance of stability and mortar, it is added in the gypsum of preparation
For the cellulose ethers that particle is tiny, soluble, thermal stability is high as water-retaining agent, addition content is 1-5 ‰, specifically can be according to master
The performance of base material is wanted to determine.
The operability of setting time is the important indicator of lightweight plastering gupsum.To make lightweight plastering gupsum have in construction
Enough operating times should ensure that there is large range of adjustment in lightweight plastering gupsum setting time.Because lightweight plastering gupsum forms
The match ratio of raw material is different, and pH value has very big difference, the function and effect of retarder also different, experiments have shown that：Each retarder
All there are one the pH range of effect, most of retarder are suitable for using under conditions of neutral meta-alkali, and application surface is relatively narrow.This Shen
The protein-based efficient compound retarder that please be prepared is suitable for the lightweight plastering gupsum of 8-13 range of pH value, particularly with profit
It is more effective in the higher lightweight plastering gupsum of pH value prepared with gypsum composite gelled material.According to the operable of construction requirement
Time（More than or equal to 60min）, retarder addition content can control between 5-20 ‰.
To ensure plastering gupsum moderate strength, and there is preferable cohesive force with substrate, avoids coat of plaster cracking, empty
The drawbacks such as drum, picking add adhesive in plastering gupsum, to improve the interparticle adhesion strength of gypsum composite gelled material
And using it during brushing gypsum dry through, it is discharged with moisture and moves to surface, plastering hardness can be enhanced
Characteristic.The mobility of slurry, adhesive addition content 0.1%-can be changed during lightweight plastering gupsum mix use simultaneously
0.3% is advisable.
Due to added in lightweight plastering gupsum water-retaining agent, adhesive and increase the viscosity of slurry, affect workability, grasp
Make difficult, be not easy to smooth out, particularly with lightweight plastering gupsum operation bring it is unfavorable.It is added in lightweight plastering gupsum thus suitable
The bubble that can generate of amount reduces the air entraining agent of plastering resistance to improve the workability and operability of slurry.Simultaneously because
The incorporation of air entraining agent increases the paste producing amount of lightweight plastering gupsum slurry, reduces unit consumption, cost reduction.Bleed
Agent addition content 0.05% -0.07% is advisable.
Following table is the properties of the lightweight plastering gupsum of this formula of the present invention：
Lightweight plastering gupsum is to be dehydrated into half-H 2 O calcium sulphate by low temperature calcination by calcium sulphate dihydrate, is forged using secondary high-temperature
It burns, becomes dead plaster after dehydration, air-setting cementing material made of blast blending and filler material.
In use, after lightweight plastering gupsum adds water mix, aquation generates dihydrate gypsum crystal and a small amount of other additives
Matter, then with machine mixing, the body structure surface for smearing pressure absorbs part moisture content by the moisture evaporation and wall of slurry, makes brushing gypsum
Continuous condensation hardening, completes Troweling press finishing before its final set, it is made to be firmly bonded with structured base layer, formed smooth, fine and smooth
Finish coat.Other architectural surfaces can be preferably done on the layer of this face.
