Problems solved by technology

[0005] At present, landfill is the main treatment method for acrylic artificial stone waste powder, but landfill occupies limited cultivated land, which is a serious waste of the country's limited land resources. The resin is stable in nature and difficult to degrade after landfill. If they stay in the soil, they will damage the air permeability of the soil. Reduce the water storage capacity of the soil, affect the absorption of water and nutrients by crops, hinder the growth of the root system of seedlings, cause a significant reduction in crop production, and lead to a reduction in arable land area

Embodiment 1

[0030] (1) The preparation of modified acrylic artificial stone waste powder comprises the following steps:

[0031] T1: configuration of titanate coupling agent solution, prepare titanate coupling agent solution with titanate coupling agent and absolute ethanol according to the mass ratio of 1:5;

[0032] T2: Preparation of acrylic artificial stone waste powder. Add acrylic artificial stone waste to a ball mill for grinding and refinement. After grinding, sieve through a 200-mesh standard sieve to obtain acrylic artificial stone waste powder. The speed of the ball mill is 400r / min~500r / min min, the grinding time is 1h~1.5h;

[0033] T3: Preparation of acrylic artificial stone waste powder dispersion. Place the acrylic artificial stone waste powder in step T2 in a dispersion container filled with deionized water, and ultrasonically vibrate for 1 hour to obtain acrylic artificial stone waste powder dispersion. The mass ratio of stone waste powder to deionized water is 1:20;

...

Embodiment 2

[0040] The difference between Example 2 and Example 1 is that (1) the preparation of modified acrylic artificial stone waste powder, the mass ratio of titanate coupling agent solution to acrylic artificial stone waste powder in step T4 is 1:100; (two ) Using acrylic artificial stone waste powder to prepare ABS flame-retardant composite materials, step S2 raw materials are pre-mixed, 100 parts of dry ABS resin, 30 parts of modified acrylic artificial stone waste powder, 3 parts of compatibilizer SMA-800, compatibilizer ABS -2 parts of g-MAH, 15 parts of flame retardant bisphenol A bis(diphenyl phosphate), 0.8 parts of lubricant zinc stearate and 0.7 parts of antioxidant 618 were added to the high-speed mixer in sequence, and stirred and mixed for 10 minutes. A mixture of raw materials was obtained.

Embodiment 3

[0042] The difference between Example 3 and Example 1 is that (1) the preparation of modified acrylic artificial stone waste powder, the mass ratio of titanate coupling agent solution to acrylic artificial stone waste powder in step T4 is 1:150; (two) ) Using acrylic artificial stone waste powder to prepare ABS flame-retardant composite materials, step S2 raw materials are pre-mixed, 100 parts of dry ABS resin, 40 parts of modified acrylic artificial stone waste powder, 4 parts of compatibilizer SMA-700, compatibilizer ABS -5 parts of g-MAH, 20 parts of flame retardant triphenyl phosphate, 0.5 parts of lubricant ethylene bis stearic acid amide, 0.5 parts of lubricant silicone powder, 0.5 parts of antioxidant 168 and 0.3 parts of antioxidant 1076 Sequentially add to a high-speed mixer, stir and mix for 20 minutes to obtain a raw material mixture.

Abstract

The invention discloses an ABS flame-retardant composite material prepared by using acrylic artificial stone waste materials and a preparation method thereof. The ABS flame-retardant composite material comprises (by weight): 100 parts of dry ABS resin, 5-40 parts of modified acrylic artificial stone waste powder, 4-10 parts of a compatilizer, 5-25 parts of a flame retardant, 0.5-1 part of a lubricant and 0.5-1 part of an antioxidant. The modified acrylic artificial stone waste powder is obtained after acrylic artificial stone waste powder undergoes surface treatment by using a coupling agent.It is ensured that the ABS composite material has excellent flame retardant property and mechanical properties. According to the ABS flame-retardant composite material, latent resource attributes of acrylic artificial stone waste materials are fully utilized, and the problem of solid wastes generated by acrylic artificial stone waste materials is solved. The ABS flame-retardant composite materialhas good economic and social meaning. The preparation method comprises the following steps: pretreatment of raw materials, premixing of raw materials, and preparation of the ABS flame-retardant composite material. The preparation method has simple operation steps, has strong practicality, and is easy for industrial implementation and promotion and application.

Description

technical field [0001] The invention relates to the technical field of flame-retardant materials, in particular to an ABS flame-retardant composite material prepared from acrylic artificial stone waste and a preparation method thereof. Background technique [0002] Artificial stone uses resin as binder, natural stone crushed (powder) material, aluminum hydroxide powder, calcium carbonate, quartz sand, etc. It is a kind of artificial stone made by casting, grinding and polishing. Artificial stone has beautiful shape, natural and uniform color, smooth surface without pores, easy to clean and maintain, water-resistant, heat-resistant, oil-proof, anti-corrosion, fire-proof, and has high rigidity, hardness, bending strength, scratch resistance, aging resistance , Dimensional stability and resistance to sudden cold and sudden heat. It is easier to process than natural stone. It can be spliced ​​and bent into various shapes to make a seamless splicing effect. At the same time, it ...
