Abstract

The invention belongs to the technical field of high-molecular material modification and processing and discloses a flame-retardation enhanced epoxy plastic sheet material and its preparation method. The epoxy plastic sheet material comprises the following ingredients of: by weight, 100 parts of epoxy resin, 5-20 parts of a plasticizer, 3-15 parts of a flexibilizer, 80-150 parts of reinforced fibers, 0-100 parts of a filler, 8-15 parts of a diluent, 15-30 parts of a fire retardant, 3-8 parts of a flame-retardation synergistic agent and 5-18 parts of a curing agent. In comparison with the prior art, the flame-retardation enhanced epoxy plastic sheet material provided by the invention has advantages of strong strength, good toughness, impact resistance, long service life, low cost, flame retardation and good flame resistance, is easy to process, and can meet the criteria at V-0 level of UL-94. The material provided by the invention can be widely applied in many national economical fields such as automobile, building sheet material and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification and processing, and relates to an epoxy plastic plate and a preparation method thereof. Background technique [0002] With the development of the automobile industry, my country's automobile production has grown steadily, and the scale of automobile consumption has become increasingly large. According to data released by the China Association of Automobile Manufacturers, my country's output reached 9.3451 million vehicles in 2008, and the sales volume of automobiles reached 9.3805 million vehicles. Although the global economic crisis has had a serious impact on the auto industries of various countries, domestic auto manufacturers have actively responded, and with the support of government policies, China's auto sales have recently begun to pick up. From the perspective of the overall trend, my country's auto industry will still maintain a stable Sustained rapid growth. While...
