Description
Technical field
The present invention relates to building material industry industrial furnace equipment thermal technology pipeline vapor line heat preservation energy-saving paint field, especially about a kind of thermal insulation coatings and production method thereof of expanded and vitrified small ball.
Technical background
Present existing thermal insulation coatings composite heat-isolating silicate paint and hard rankinite insulation coating, all be to be the thermal insulation coatings of stopping composition type with perlite, expanded vermiculite, diatomite, wilkinite, their water-intake rate is big, and unit weight is big, and its component asbestos contain carcinogenic factor.The commercial plant that silicate coating can only be used for below 700 ℃ uses, and its thermal conductivity is at GB/T17371-1998, and the national standard premium grads is: medial temperature 343K ± 5K time≤0.06W/ (m.k).Slurry density≤1000kg/m
3, volumetric shrinkage is up to≤30%, and its major cause is that water-intake rates such as pearl, diatomite, wilkinite are several times of self material deadweight.This is the shortcoming that original thermal insulation coatings can't overcome, so that bring shortcomings such as use temperature is low, shrinking percentage is big, water consumption is big, thermal conductivity height, causes mixed economy cost height.
Summary of the invention
At above deficiency, the object of the present invention is to provide a kind of is main material with expanded and vitrified small ball, expansion vitrification bead heat-preserving paint and production method thereof that process special producing processes forms.
Technical scheme of the present invention realizes in the following manner, and expansion vitrification bead heat-preserving paint, its composition comprise following component (representing with wt.%):
Expanded and vitrified small ball 8-11%, the cotton 4-6% of high aluminum silicate, brucite suede 5-10%, permeate agent 0.5-2%, binding agent 5-10%, silicon calcium powder 3-7%, water 55-75%.
In above-mentioned thermal insulation coatings; expanded and vitrified small ball is a kind of unorganic glass matter mineral material; be irregular spherule particle; inner porous air cavity configuration; surface vitreous sealing, gloss is level and smooth, and physicochemical property is steady; have light weight, thermal insulation, fire prevention, high-low temperature resistant, anti-aging, excellent specific property such as water-intake rate is little, overcome the high defectives of material water-intake rate such as perlite, closed perlite, diatomite, wilkinite.The above-mentioned percentage range of the combination of these components and each component, determine that by a large amount of tests the coating that aforesaid combination and percentage range form coating composition of the present invention has that volumetric shrinkage is little, thermal conductivity is low, long service life, the cheap a kind of heat insulating energy saving material of mixed economy.This coating insulation use temperature scope is between-80-1100 ℃.
Above-mentioned binding agent is that concentration is the polyvinyl alcohol of 2-3% polyacrylamide or 8%, preferentially is polyacrylamide.
Above-mentioned permeate agent is at least a in the sulfosuccinate ester class.
Above-mentioned permeate agent is dioctyl sodium sulfosuccinate, succinate sodium sulfonate, sulfosuccinate ester in the last of the ten Heavenly stems or polyethenoxy ether class compounds preferably, preferentially is dioctyl sodium sulfosuccinate.
Production method of the present invention may further comprise the steps successively:
1), at normal temperatures in above ratio with tap water,, the expanded and vitrified small ball of high aluminum silicate cotton, brucite suede, silicon calcium powder, 1/2 binding agent and 1/4-1/3 mixes and stirred 15-20 minute;
2), adding all the other binding agents stirred one-tenth pasty state coating 3-5 minute;
3), change coating over to forced stirrer, add all the other expanded and vitrified small balls, stirred 4-5 minute, the paste vitrification bead heat-preserving paint.
Expansion vitrification bead heat-preserving paint of the present invention can adopt conventional the coating, for example equably coating is coated on stove, oil pipeline, steam pipeline by trowelling, spraying method and has on the special-shaped equipment of thermal source.Because expanded and vitrified small ball is formed via special process and 1200 ℃ of-1300 ℃ of thermosols by pitchstone, water-intake rate is little, therefore plays high insulating effect in product, and volumetric shrinkage is little.The advantage that it has: 1) thermal conductivity is low is 0.032-0.045; 2) water-intake rate≤45; 3) tap density≤80kg/m
34) the showy rate of volume 〉=80%; With the glass bead is the thermal insulation coatings of major ingredient, and the advantages of excellent stability energy is arranged, and dry density is little, and thermal conductivity is low, the use temperature height, and volumetric shrinkage is little, and mixed economy is cheap, is nontoxic, harmless, free of contamination environmental protection and energy saving material.Expansion vitrification bead heat-preserving paint of the present invention insulation use range is at-80-1100 ℃.
