Problems solved by technology

[0004] Although the above-mentioned patents have prepared a high-gloss black, high-hardness, and weather-resistant PMMA / ASA alloy material, the high-gloss black itself belongs to the chemical properties of the PMMA polymer itself, and ASA itself has weather resistance, so there is no need to add a weather-resistant agent separately, which increases the cost of raw materials put in

Abstract

The invention discloses a spraying-free metal weather-resistant PMMA / ASA alloy material. The spraying-free metal weather-resistant PMMA / ASA alloy material comprises the following formula components in parts by weight: 30-35 parts of PMMA resin, 25-30 parts of ASA resin, 10-12 parts of quartz powder, 2-4 parts of an active agent, 1-10 parts of color master batch and 0.8-1.2 parts of an antioxidant. And 5-8 parts of paraffin with the content of 2%-3%. The quartz powder is added into the PMMA resin and the ASA resin, the PMMA resin has good high brightness, so that the surface of the alloy material is bright, the surface roughness, the surface wear resistance and the weather resistance are improved through the quartz powder, the liquid paraffin can be used as a lubricant and a surface protective agent, and the service life of the alloy material is prolonged. And the wax layer is used for sealing, oxygen is isolated, oxidability is reduced, and the alloy material further achieves good weather resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer alloy material production, and in particular relates to a metal weather-resistant PMMA / ASA alloy material without spraying. Background technique [0002] ASA resin is made of acrylonitrile (A), styrene (S), acrylate (A) ternary graft copolymer (also known as AAS), which is widely used in electronic appliances, automobile industry, outdoor products and other fields. With the improvement of people's aesthetics, the pursuit of different colors is different. In addition to the good weather resistance and colorability of ASA itself, it can be dyed into colorful without fading, and it can be directly processed and injected into colorful products without painting. Therefore, ASA materials can be used as outdoor products; PMMA materials are one of the directions of high-gloss extrusion products, so an appropriate proportion of PMMA can be added to prepare high-gloss, high-surface-hardness ASA materials, i...
