Abstract
The invention relates to a glass fiber reinforced plastic material for embossment forming. The glass fiber reinforced plastic material is prepared from the following raw materials in parts by weight:100 parts of epoxy modified polypyrazolo [1, 5-A]-1, 3, 5-triazine-2, 4 (1H, 3H)-diketone 3, 3-difluoro-[1, 1-biphenyl]-4, 4-dicarboxylic ester, 6-10 parts of 1, 3, 5, 7-tetra (4-aminophenyl) adamantane, 15-20 parts of glass fiberpowder, 3-6 parts of graphemefiber, 10 to 15 parts of an inorganic filter, and 5 to 10 parts of a release agent. The invention further discloses a preparation method ofthe glass fiber reinforced plastic material for embossment forming. The glass fiber reinforced plastic material for embossment forming is better in comprehensive performance, better in high-temperature resistance and abrasion resistance, more excellent in oxidation resistance, flame retardance, mechanical property and water resistance, higher in toughness, not easily damaged, and long in servicelife.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a glass fiber reinforced plastic material for relief molding and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the progress of society, people's aesthetic concept has gradually deepened, and their pursuit of visual beauty has become more and more intense. There is an increasing demand for reliefs for architectural decoration, garden landscape, especially for large bas-reliefs. Relief not only has the characteristics of hard, wear-resistant and heavy weight of natural stone, but also its texture, strong plasticity and expressiveness, which can make it show various artistic styles. In the decorative space, the natural decorative effect and artistic connotation shown are unmatched by other decorative materials. [0003] At present, the raw materials for making reliefs are usually mud, wood, stone or ...
