Abstract

The invention relates to anti-fingerprint stain-resistant PMMA resin and a preparation method thereof. The anti-fingerprint stain-resistant PMMA resin comprises the following components in parts by weight: 45-80 parts of PMMA, 5-25 parts of anti-fingerprint master batches, 15-30 parts of a toughening agent, 0.1-1 part of an antioxidant, 0.1-1 part of a lubricating agent and 0.1-1 part of a weather-resistant agent. Compared with the prior art, the anti-fingerprint stain-resistant PMMA resin and the preparation method thereof provided by the invention have the benefits that a fluorosilicone polymer is introduced into PMMA resin and is made into the anti-fingerprint master batches together with the PMMA and a compatilizer, so that the compatibility of the polymer with the PMMA resin is improved, the fluorosilicone polymer is better dispersed in the PMMA, the surface tension of the PMMA resin is greatly reduced, the fingerprint resistance and the anti-fouling property of the PMMA resin are improved, and meanwhile, the low temperature toughness is also improved; the anti-fingerprint stain-resistant PMMA resin can meet the requirements of a host plant for fingerprint resistance to the surface of an automotive exterior part and can be used in automotive rearview mirrors, B-pillars, grilles and other automotive spraying-free exterior parts.

Description

technical field [0001] The invention relates to a modified PMMA resin, in particular to an anti-fingerprint and stain-resistant PMMA resin and a preparation method thereof. Background technique [0002] Polymethyl methacrylate (PMMA) has excellent weather resistance, high surface hardness, good high temperature performance, excellent coloring performance and transparency, and is widely used in aviation, automobile, electronics, medical, chemical, building materials, sanitary and Billboards and other industries have been widely used, but ordinary PMMA has limited its further application due to its low elongation, cracking and fragility. [0003] With the enhancement of people's awareness of green environmental protection, the application of spray-free materials in the interior and exterior of automobiles is becoming more and more extensive. Due to its special high gloss and high blackness, scratch resistance and weather resistance, toughened PMMA has gradually become an autom...
