Embodiment 1

[0017] Embodiment 1 of the present invention: polyester artificial marble, calculated in parts by mass, includes 10 parts of resin, 22.4 parts of marble waste rock powder, 33.6 parts of quartz sand, 10 parts of calcium hydroxide, 10 parts of calcium carbonate, 1.5 parts of accelerator Agent, 1 part of curing agent and 11.5 parts of pigment; described resin, in described resin, add the nanometer titanium dioxide that accounts for 3% of resin gross mass.

[0018] The preparation method of polyester type artificial marble, gets each component by above-mentioned parts by weight, comprises the steps:

[0019] 1) Add the accelerator and pigment into the resin for stirring and mixing, and after mixing thoroughly, obtain the mixture A;

[0020] 2) Mix mixture A with marble waste rock powder, quartz sand, calcium hydroxide and calcium carbonate, and stir for 1-3 minutes to obtain mixture B;

[0021] 3) After mixing the mixture B and the curing agent evenly, pour it into the mold, vacu...

Embodiment 2

[0022] Embodiment 2 of the present invention: polyester artificial marble, calculated in parts by mass, includes 8 parts of resin, 25 parts of marble waste rock powder, 35 parts of quartz sand, 8 parts of calcium hydroxide, 12 parts of calcium carbonate, 1 part of accelerator Agent, 1 part of curing agent and 11 parts of pigments; described resin, adding 2% nano-titanium dioxide accounting for the total mass of the resin in the resin.

[0023] The preparation method is the same as in Example 1.

Embodiment 3

[0024] Embodiment 3 of the present invention: polyester artificial marble, calculated in parts by mass, includes 12 parts of resin, 20 parts of marble waste rock powder, 35 parts of quartz sand, 12 parts of calcium hydroxide, 8 parts of calcium carbonate, 2 parts of accelerated Agent, 2 parts of curing agent and 13 parts of pigment; described resin, in described resin, add the nanometer titanium dioxide that accounts for 4% of resin gross mass.

[0025] The preparation method is the same as in Example 1.

[0026] In the above examples, the resins described are all artificial stone special resins, and the artificial stone special resins adopted in the above examples are commercially available 885# unsaturated polyester resins, but, according to different purposes, those skilled in the art can Choose resin binder flexibly. In the preparation process of high-transparency artificial stone, vinyl ester resin (VE) is usually selected; the use of specific resin can choose different r...

Abstract

The invention discloses polyester type artificial marble and a preparation method thereof. The polyester type artificial marble is prepared from, by mass, 8-12 parts of resin, 20-25 parts of waste marble powder, 30-35 parts of quartz sand, 8-12 parts of calcium hydroxide, 8-12 parts of calcium carbonate, 1-3 parts of accelerant and 1-2 parts of curing agent. By means of reasonable screening of material components and use quantities, the prepared artificial marble has excellent mechanical properties, the application range of the artificial marble is greatly expanded, the adopted materials are wide in source and low in cost, the preparation method is very simple, easy to implement and suitable for large-scale production, the method is reliable, and the use effect is ideal.

Description

technical field [0001] The invention relates to the field of artificial stone preparation, in particular to a polyester artificial marble and a preparation method thereof. Background technique [0002] The scientific name of artificial stone is solid surface material. Unsaturated polyester artificial marble is based on unsaturated polyester resin as binder, adding inorganic fillers, pigments, curing agents and other auxiliary reagents. A composite material obtained by curing and molding. The vacuum-pressed block type, plate type and solid surface material type products made of unsaturated polyester resin as binder all belong to the scope of protection of this patent. [0003] Existing artificial stones are usually light in weight, strong in alkali resistance, good in texture and beautiful in appearance. However, in the actual application of artificial stone, polyester artificial marble often has the characteristics of low hardness, poor wear resistance, poor flame retardan...
