Problems solved by technology

However, if the acrylic toughening agent is used alone, the weather resistance of the material will be lost more, and the toughening efficiency will not be high, and as the addition of the toughening agent continues to increase, the gloss of PMMA resin will decrease significantly.

Abstract

The invention discloses a spraying-free, heat-resistant and weather-resistant high-brightness PMMA alloy material and a preparation method thereof. The spraying-free, heat-resistant and weather-resistant high-brightness PMMA alloy material is prepared from the following components in parts by weight: 70 to 75 parts of PMMA resin, 5 to 20 parts of a compound flexibilizer, 0 to 5 parts of a heat resisting agent, 0.2 to 0.5 part of a light stabilizer, 0.3 to 0.5 part of an antioxidant, 0.2 to 0.3 part of a lubricating agent and 0.5 to 1.0 part of a toner, wherein the compound flexibilizer is prepared by compounding acrylate and organic silicon resin according to a mass ratio of 3 to 1; the heat resisting agent is customized LMPB-g-MAH. By the adding of the crylic acid and organic silicon compound flexibilizer into the PMMA resin, the PMMA resin material is high in impact strength and weather resistance; the heat resisting agent is added into the PMMA resin, the PMMA material is high in heat resistance; therefore, the PMMA material can be molded through one-time injection, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a spray-free, heat-resistant, weather-resistant high-gloss PMMA alloy material and a preparation method thereof. Background technique [0002] PMMA (polymethyl methacrylate) resin is an important synthetic resin. PMMA resin is the most excellent and relatively affordable variety of synthetic transparent materials so far. It is widely used in instrumentation parts, automobile lights, and optical lenses. , Transparent pipeline. PMMA is light in weight, and its density is lower than that of glass; PMMA has high mechanical strength, and its relative molecular mass is about 2 million. It is a long-chain polymer compound, and the chain forming the molecule is very soft, so its strength is relatively high. It has high tensile and impact resistance, better impact resistance than polystyrene and is not easily broken. PMMA is currently the most excellent polymer transparent mat...
