Description

A simulation method of sandstone

technical field

The invention relates to a method for simulating the texture of natural stone, in particular to a method for simulating sandstone.

Background technique

Natural stone is one of the symbols of nature; adding natural stone elements to the living environment can create an atmosphere close to nature and advocating ecology, so it is favored by many people.

However, it is not easy to use natural stone in the home environment, and it requires a lot of manpower and material resources. For this reason, the inventor decided to look for a kind of simulation method of natural sandstone.

Contents of the invention

The technical problem to be solved by the present invention is to provide a simulation method of natural sandstone. The decorative panel surface prepared by this method should present a color effect similar to the texture of sandstone, and has the advantages of easy availability of raw materials, convenient production and low cost features.

The technical scheme provided by the invention is:

A simulation method for sandstone, comprising the following steps in sequence:

1) Apply 2 to 4 layers of putty on the surface of the substrate

First, the putty is toned to the main color of the stone to be made, and then applied to the base material in batches, dried and then polished;

2) spray paint

Spray 1-2 coats of water-in-water colorful paint on the surface of the polished putty layer;

3) Grinding

Sand off the surface of the paint with sandpaper to expose the mixed layer of putty and paint;

4) Cover light

Covering protection is sprayed with varnish; the varnish is one of water-based silicone acrylic resin, water-based fluorocarbon resin or water-based polyurethane resin.

The composition and parts by weight of the putty layer are: titanium dioxide 20, heavy calcium 80, quartz sand 700, acrylic emulsion 180, film-forming aid 9, antifreeze 3, plasticizer 3, defoamer 3, buffer 1 , Dispersant 5, Bactericide 1, Preservative 1, Water 102.

The sandpaper is 80-160 mesh.

The beneficial effects of the present invention are: because plasticizer is added in the putty used, it becomes easy to polish during construction, and also facilitates the infiltration of surface coating; The permeability of organic silicon makes the water-in-water coating very easy to penetrate into the putty layer, and it is easy to penetrate the inner layer of the putty after spraying it; finally, after the surface layer is polished off, the infiltrated paint and putty together show a seamless, similar to natural sand The color effect of rock markings. In addition, all the raw materials are cheap and easy-to-buy conventional raw materials, and the production process is simple, so the production cost is not high.

detailed description

The idea of the present invention is to provide a method for making imitation natural sandstone with a high degree of simulation. Specifically go through the following steps:

1) Apply 2 to 4 layers of putty on the surface of the substrate

First, the putty is toned to the main color of the stone to be made, and then applied to the substrate in batches to form a putty layer, which is dried and then polished. The raw material of the putty is to add a certain amount of plasticizer in addition to the conventional raw materials, so that it becomes much easier to polish during construction, and a porous network coating structure is formed at the initial stage of drying, which can make the water-in-water coating on the surface It penetrates into the inner layer of putty more smoothly and improves the simulation effect.

2) spray paint

Spray 1-2 coats of water-in-water multicolor paint on the surface of the polished putty layer; the water-in-water multicolor paint is organic silicon water-based multicolor paint, and the color can be determined according to the type of stone material required.

3) Grinding

The grinding tool used is 80-160 mesh sandpaper; the surface layer of the paint is polished off to expose the mixed layer of putty and paint interlaced;

4) Cover light

Covering protection is sprayed with varnish; the varnish is one of water-based silicone acrylic resin, water-based fluorocarbon resin or water-based polyurethane resin.

Example 1

light gray sandstone

1) Tone the putty to light gray first, then apply it to the wood in batches for 2 coats of putty, dry and polish;

2) spray 2 roads of water-in-water colorful paint on the surface of the putty layer after polishing; the color point color in the water-in-water colorful paint is gray;

3) The grinding tool used is 100-mesh sandpaper; the surface layer of the paint is polished to expose the mixed layer of putty and paint interlaced;

4) Spray 1 coat of water-based silicone acrylic resin to cover and protect.

Example 2
