Abstract
The invention discloses a manufacture method of polyurethane material composite rock culture wall bricks. The method has the advantages that polyurethane material serves as a rock embossment, and the fluctuation part on the surface of the rock embossment is marked with hunting or working models of people in the ancient age and is also marked with ancient age words. The cost is increased if only a polyurethane foaming material is used, and planer stress deformation is generated when a culture wall brick with the size of 40-50cm is manufactured. In the manufacture method disclosed by the invention, a common nine-layer plate or a medium-density plate with the thickness of 6cm is adopted, the cheap decorative material is used to lower cost and add the weight sense of the polyurethane, the problem of deformation is solved, and the cheap decorative material is easy to install.
Description
Technical field:
The invention belongs to light body building and ornament materials, specially refer to a kind of preparation method of polyurethane material composite rock culture wall brick.
Background technology:
The city real estate of China is flourish, various ornament materials emerge in an endless stream, existing various culture wall brick, culture wall brick as rock material mostly is natural edge green stone, also have other versicolor granite to be cut into the culture wall brick of all size, this in fact stone product, do not have cultural connotation, also without any the form of expression of cultural Symbol, existing a kind of culture wall brick that is carved with Egyptian sculpture is artificial sandstone material, because the very big cost in addition of weight is too high, be difficult to popularize.
Advantage of the present invention is to adopt the embossment of polyurethane material as rock, the surface undulation part of rock embossment, be carved with the ancient times people and keep the moulding of hunting or working, the literal that the part ancient times is also arranged, we know if use polyurethane foam material merely, cost is raise, by especially making the culture wall brick of 40～50 centimeter square, can produce the stress modification on plane, and the present invention the nine common laminates or the medium-density plate of six cm thicks have been adopted, does composite with the ornament materials of this cheapness, promptly reduced cost, increased the weight sense of polyurethane again, also solved the problem of modification, installed well again.
Technology contents:
Existing culture wall brick mould is ready to, and on the organic silicon rubber mould, spray one deck Self-spraying wax polish, this wax is spray car instrument board wax, the polyurethane foam material that adopts Tianjin national practice of forms of behavior polyurethane Co., Ltd to produce, the preparation setting time is two kinds of materials of AB of 70 seconds, according to the prototype organic silicon rubber mould of the culture wall brick of 40 centimetres of sides, if the pattern complexity can be made of material in polyester resin, in mould, put into 6 millimeters thick medium-density plates then, pour A into and expect 200 grams, B material 200 grams, two kinds of 30 seconds kinds of the quick stirring of agitator that material is made with power drill, pour in the mould then, build charging aperture, can reserve steam vent, so that in the expanded foamed process of polyurethane the place of giving vent to anger is arranged on concavo-convex outstanding sculpture ground, make sculpture after expansion is full of mould, do not have micropore and fill less than the place.
Specific embodiments:
1. with the culture wall brick prototype mould of 40 centimeter square, mould is selected organic silicon rubber and two kinds of materials of fiberglass for use, and known method is adopted in Mold Making, prepares the medium-density plate of 6 cm thicks, 40 centimeter square.
2. prepare the expanded material of the polyurethane of 1000 grams, A component and B component be 500 grams respectively, and the stirring that is not mixed earlier is because two kinds of materials of AB of 1000 grams only need stir and finish for 30 seconds.
3. in the ready organic silicon rubber mould, spray one deck releasing agent, releasing agent adopts wax material, most convenient be Self-spraying wax polish, with automobile instrument panel wax polish or get on the bus wax can, the glossiness that how much determines works of wax spray is put into mold bottom to medium-density plate.
4. stir the polyurethane AB material of 1000 grams fast with 30～60 seconds, mixer is optional with card one T font stirring rod on the electric drill, whole AB materials are mixed evenly at short notice, pour foaming in the mould then into, if recessed very dark place is arranged in the works, this just need be when pouring material into, stir about one cubic centimetre earlier, the AB compound of this cubic centimetre, wiping is at the recess of mould, after all material was poured into mould like this, local few one phenomenon just can not appear.
5. after pouring all material into, see when expanded material is heaved the die feeding mouth, pressing the mould blank cover, material in mould like this, can expand into any old place of mould fully, not cover charging aperture if do not push down, the blown polyurethane materials of expansion will all be overflowed from the top, blown polyurethane materials density in the mould is reduced, influence product strength.
6. pour 5 minutes after coagulations of polyurethane foam material foaming of mould into, can open the outside hard mold of mould after solidifying, open the organic silicon rubber soft mold again, carrying out deburring after the goods taking-up, find that defective place can allocate 1 A again, the B component, promptly can spray the needed color coating of goods after filling, can be monochromatic, it also can be multiple color, if make 50 centimetres to 100 centimetres polyurethane material composite rock culture wall brick, the weight of sensation works is too light, can not pour into a mould A, during the B polyurethane foam material, put into weighting materials such as timber and lumber core, these materials can contain in foaming.
7. make the prototype of rock culture wall brick, the effect of height emulation can directly can occur with existing various rough natural former stones.
Claims (1)
