Problems solved by technology

As a new type of organic decorative material, acrylic sheet gradually plays an important role in people's daily life. In the market, general acrylic sheets are rich in color and variety, but their strength and toughness are not high, and they are expensive. They are used as cabinet panels and other products. Most of the acrylic sheets are filled with marble, which has high strength, but poor toughness and bulkiness.
At the same time, these acrylic sheets are flammable products

Embodiment 1

[0022] 1) Preparation of waste organic glass solution

[0023] First, the waste organic glass is cleaned, dried, and pulverized into granules or powder, and then 60 grams of granular or powdery waste organic glass is dissolved with 100 grams of methyl methacrylate under stirring to obtain a waste organic glass solution;

[0024] 2) Preparation of mixed slurry

[0025] Add respectively 0.3 gram of dibenzoyl peroxide, 25 gram of wood processing plant waste sawdust, 30 gram of dried particle diameters of 200-400 mesh flame retardant magnesium hydroxide and 0.4 gram of waste plexiglass solution under agitation. The antifoaming agent organosilicon monomer is evenly mixed to obtain a mixed slurry; the sawdust is dried, crushed and sieved, and its particle size is 80-120 mesh;

[0026] 3) Pour the mixture slurry into the mold after ultrasonic placement for 20 minutes, after pouring into the mold, let it stand at room temperature for 20 minutes, then place the mold in an oven, and us...

Abstract

The invention relates to a preparation method of an antiflaming heat insulation acrylic plate. The plate is prepared through the following steps: carrying out dissolution, mixing, pouring and polymerization on the following raw materials by weight: 100g of methyl methacrylate, 0.3-0.5g of benzoperoxide, 60-100g of waste organic glass, 25-40g of wastes in a wood processing plant, 0-10g of colouring pigment, 30-60g of fire retardant and 0.4-0.8g of defoamer. According to the plate, the defects of the traditional acrylic plate, such as low strength, low hardness, poor toughness, poor heat resistance and the like, are overcome; the waste utilization rate is increased, environment pollution is reduced, and the production cost is lowered; and simultaneously, the plate prepared by the method hasantiflaming and heat insulation functions and can be widely applied to building and home decoration industries.

Description

technical field [0001] The invention belongs to plastic casting plates, in particular to a preparation method of flame-retardant and heat-insulating acrylic plates. Background technique [0002] With the gradual improvement of people's living standards, various decorative materials appear in major public places, luxury hotels, shopping malls and families. As a new type of organic decorative material, acrylic sheet gradually plays an important role in people's daily life. In the market, general acrylic sheets are rich in color and variety, but their strength and toughness are not high, and they are expensive. They are used as cabinet panels and other products. Most of the high-end acrylic sheets are filled with marble, which has high strength, but poor toughness and bulkiness. At the same time, these acrylic sheets are flammable products. [0003] Sawdust is the main waste of wood processing plants. At present, it is mainly used in cultivating edible fungi, making charcoal,...
