preparation example Construction

[0017] The present invention also provides a kind of preparation method of artificial marble, comprises the following steps:

[0018] A) Add 3-20 parts by weight of sodium hydroxide or potassium hydroxide solution to 80-120 parts by weight of wood powder under stirring, and obtain alkalized wood powder after suction filtration;

[0019] B) uniformly mixing the alkalized wood powder with 40-60 parts by weight of talcum powder and 0.5-3 parts by weight of silane coupling agent, drying to obtain a filler mixture;

[0020] C) uniformly mixing 100 parts by weight of unsaturated polyester resin and 0.7-1 part by weight of cobalt naphthenate to obtain a resin mixture;

[0021] D) Then mix the resin mixture and the filler mixture evenly, finally add 1-1.5 parts by weight of methyl ethyl ketone peroxide, start stirring to obtain a material without bubbles, and cast the material to obtain the artificial marble.

[0022] According to the preparation method of the present invention, in s...

Embodiment 1

[0032] (1) Put 100 parts by weight of 200-mesh wood powder into a stirring device, add 10 parts by weight of sodium hydroxide solution (concentration: 17.5 wt%), stir for 4 hours, and filter out the liquid to obtain alkalized wood powder;

[0033] (2) Add the above-mentioned alkalized wood powder and 40 parts by weight of 200 mesh talcum powder into a high-speed mixer, and directly spray 1 part by weight of a silane coupling agent on the surface of the alkalized wood powder and talcum powder in the high-speed mixer, Start the stirring, the stirring speed is 100r / min, and the stirring time is 20min; after the stirring is completed, dry at 120°C for 2h to obtain the filler mixture;

[0034] (3) Put 100 parts by weight of unsaturated polyester resin, 0.7 parts by weight of color paste and 1 part by weight of cobalt naphthenate in a reaction kettle, stir and mix evenly at room temperature to obtain a resin mixture;

[0035] (4) Pour the filler mixture in step (2) and the resin mix...

Embodiment 2

[0037] Adopt the same steps as embodiment 1 to prepare the artificial marble S2 of the present embodiment, the difference is:

[0038] In step (1), the sodium hydroxide solution in Example 1 is replaced by a potassium hydroxide solution with a concentration of 20wt%, and the consumption of the potassium hydroxide solution is 20 parts by weight;

[0039] In step (2), the dosage of talcum powder is 50 parts by weight, the dosage of silane coupling agent is 1.5 parts by weight, the stirring speed is 110r / min, and the stirring time is 30min; the drying temperature is 100°C, and the drying time is 3h .

Abstract

The invention provides an artificial marble raw material composition comprising the components of, by weight, 100 parts of unsaturated polyester resin, 80-120 parts of wood powder, 40-60 parts of talcum powder, 1-1.5 parts of methyl ethyl ketone peroxide, 0.7-1 part of cobalt naphthenate, 0.5-3 parts of silane coupling agent, and 3-20 parts of a sodium hydroxide or potassium hydroxide solution. The invention also provides a preparation method of the artificial marble and the artificial marble obtained with the method. According to the invention, wood powder and talcum powder are adopted as filling materials; also, the wood powder is subjected to an alkalization treatment by using sodium hydroxide or potassium hydroxide, and a surface treatment by using the silane coupling agent, such that the obtained artificial marble has low density, light weight, good insulation performance, and good mechanical properties.

Description

technical field [0001] The invention belongs to the field of new building decoration materials, and in particular relates to a raw material composition of artificial marble and a preparation method of artificial marble. Background technique [0002] Artificial marble is a new type of building decoration material developed in recent years. It is made of unsaturated polyester resin and fillers. It has various colors, has the appearance and texture of natural granite, and has the processability of synthetic materials. It is used in building decoration. fields are widely used. [0003] At present, the preparation method of artificial stone on the market is mainly: mixing and stirring unsaturated polyester resin with curing agent, accelerator and filler, and then curing and forming in a mold. Therefore, the choice of filler directly affects the thermal insulation performance and various mechanical properties of artificial marble. At present, the commonly used artificial marble ...
