AI Technical Summary

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 solvent-resistant high-gloss spraying-free PMMA (polymethyl methacrylate) alloy material and a preparation method of the alloy material. The solvent-resistant high-gloss spraying-free PMMA alloy material is prepared from the following ingredients in parts by weight: 85-95 parts of PMMA resin, 1-5 parts of a compound flexibilizer, 5-10 parts of AS resin with ultrahigh molecular weight, 0.1-0.2 parts of a light stabilizer, 0.1-0.2 parts of an antioxidant, 0.1-0.2 parts of a lubricant and 1 part of toner, wherein the compound flexibilizer is compounded by surlyn and organic silicon resin at a mass ratio of 1:1. The prepared PMMA alloy material has better toughness, solvent resistance, thermal oxidative aging resistance and processability and is high-gloss and spraying-free.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a solvent-resistant high-gloss spray-free PMMA alloy material and a preparation method thereof. Background technique [0002] PMMA (polymethyl methacrylate) resin is an important synthetic resin. PMMA resin is by far the most excellent and cost-effective variety of synthetic transparent materials. It is widely used in instrumentation parts, automobile lights, and optical lenses. , Transparent pipeline. PMMA is lighter in weight and has a lower density than glass; PMMA has higher mechanical strength, with a relative molecular mass of about 2 million. It is a long-chain polymer compound, and the chain that forms 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 material with a visible light trans...
