preparation example Construction

[0029] Such as figure 1 Shown, landscape imitation stone preparation method of the present invention, step is as follows:

[0030] Step 1. Apply a release agent on the real stone, and use liquid phase silica gel to prepare a mold for the real stone;

[0031] Step 2. After applying the mold release agent on the inner surface of the remade mold, spray or brush the modified polyurethane material, solidify, and demould to obtain a real stone hard mold;

[0032] Step 3: Fill the inner cavity of the real stone hard mold with polyurethane foam and cure it;

[0033] Step 4: Spraying imitation stone paint on the outer surface of the real stone hard mold, drying to obtain landscape imitation stone.

[0034] In the above technical scheme, in step 1, liquid-phase silica gel is a mold-turning material commonly used by those skilled in the art, and is usually composed of silica gel and a curing agent. The curing agent mainly includes tetraethyl orthosilicate and organic tin; when the sili...

Embodiment 1

[0042] Step 1. Apply silica gel release agent (Vaseline release paste) on the real stone, and use liquid phase silica gel (HY-6, 100g of silica gel: 2g of curing agent) to prepare the mold of the real stone;

[0043] Step 2. After applying polyurethane release agent (Dakin GA-7500 fluorine high-efficiency release agent) on the inner surface of the remade mold, brush the modified polyurethane material, cure, and release the mold to obtain a real stone hard mold;

[0044] Among them, the modified polyurethane material formula is: 100 parts by weight of polyethylene glycol ether, 70 parts by weight of toluene diisocyanate, 24 parts by weight of glass fiber, 0.3 parts by weight of dibutyltin dilaurate, 0.01 parts by weight of nano-silica, 0.2 parts by weight of It consists of titanium dioxide, 7 parts by weight of thermoplastic styrene-butadiene rubber-maleic anhydride graft, 1 part by weight of zinc stearate, 0.3 part by weight of antioxidant 1010, 0.08 part by weight of paraffin ...

Embodiment 2

[0049] Step 1. Apply silica gel release agent (Vaseline release paste) on the real stone, and use liquid phase silica gel (HY-6, 100g of silica gel: 2g of curing agent) to prepare the mold of the real stone;

[0050] Step 2. After applying polyurethane release agent (Dakin GA-7500 fluorine high-efficiency release agent) on the inner surface of the remade mold, brush the modified polyurethane material, cure, and release the mold to obtain a real stone hard mold;

[0051] Among them, the modified polyurethane material formula is: 100 parts by weight of polyethylene glycol ether, 63 parts by weight of toluene diisocyanate, 12 parts by weight of glass fiber, 0.2 parts by weight of dibutyltin dilaurate, 0.01 parts by weight of nano-silica, 0.2 parts by weight of It consists of titanium dioxide, 5 parts by weight of thermoplastic styrene-butadiene rubber-maleic anhydride graft, 1 part by weight of sodium stearate, 0.2 part by weight of antioxidant 168, 1 part by weight of paraffin an...

Abstract

The invention relates to a landscape imitated stone and a preparation method thereof, belongs to the technical field of imitated stone preparation, and solves the technical problems of resource waste,high density and difficult transportation of landscape stones with natural stones as materials, and weaker fidelity and higher weight of the landscape stones with the imitated stones as materials inthe prior art. In the landscape imitated stone preparation method, releasing agents are firstly coated on real stones, and liquid-phase silica gels are adopted to prepare duplication molds of the realstones; then, after the releasing agents are coated on the inner surfaces of the duplication molds, modified polyurethane materials are sprayed or brushed for curing and demolding to obtain real stone hard molds; then, inner cavities of the real stone hard molds are filled with polyurethane foamed materials for curing; and finally, stone imitated paint is sprayed on the outer surfaces of the realstone hard molds for drying to obtain the landscape imitated stone. The landscape imitated stone is vivid in effect, good in texture, low in mass, excellent in moisture, ultraviolet, cold and heat resistance and long in service life; and the preparation method is simple and quick and low in production cost, saves the real stones, can machine various complex stone bodies, and is wide in application.

Description

technical field [0001] The invention belongs to the technical field of preparation of imitation stone materials, and in particular relates to a landscape imitation stone and a preparation method thereof. Background technique [0002] With the acceleration of urban construction, in order to create an elegant living environment for people and improve people's spiritual enjoyment and material enjoyment, landscape design has been paid more and more attention. Landscape stones are used more and more frequently in landscape design, such as patios, lawn paths, around swimming pools, railings, villa foundations, gazebos, porches and other buildings that require landscape stones for decoration and beautification. [0003] Existing landscape stones are mainly natural stones in nature, mostly granite, slate, sandstone and pebbles. Although the authenticity of natural stone is very good, stone is a non-renewable resource. With continuous mining, stone resources will become less and les...
