Abstract

The invention discloses a glass fiber reinforced PMMA composite material and a preparation method thereof, and belongs to the technical field of high polymer materials. The composite material comprises PMMA resin, modified glass fibers and a compatilizer; the surface of the modified glass fiber is coated with an impregnating compound, and the impregnating compound is composed of a silane coupling agent, a bisphenol A epoxy resin emulsion, an unsaturated polyester resin emulsion, a surfactant, a pH regulator and deionized water; the silane coupling agent is a mixture of methacrylic acid chromium tetrachloride, gamma-methacrylic acid propyl trimethoxy silane and divinyl triamine propyl triethoxy silane in a mass ratio of 1: (0.3-0.7): 0.2; and the surfactant is a mixture of fatty alcohol-polyoxyethylene ether and dodecyl dimethyl amine oxide in a mass ratio of (1-1.5): 0.5. According to the invention, the modified glass fiber is added into PMMA, so that the prepared composite material has higher mechanical properties.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced PMMA composite material and a preparation method thereof. Background technique

[0002] The Ministry of Industry and Information Technology requires that the fuel consumption target of 5L / 100km be achieved by 2020. However, in 2015, about a quarter of enterprises failed to meet the target of that year. At present, automobile manufacturers are under great pressure to save energy and reduce consumption, and automobile lightweight is an important way to achieve energy conservation and consumption reduction.

[0003] The lightweight of automobiles is a concern of both consumers and car companies. In order to achieve the goal of lightweight, in addition to optimizing the structure and process design, the selection of materials is also very critical. In order to reduce the weight of cars, car companies use a large number of engineering plastics, espe...
