Environment-friendly high-polymer board with oil resistance and high temperature resistance performances and preparation method thereof

Abstract

The invention relates to an environment-friendly high-polymer board with oil resistance and high temperature resistance performances. The environment-friendly high-polymer board consists of the following components as raw materials in parts by weight: 30-35 parts of waste residues of a power plant, 20-30 parts of asphalt, 35-45 parts of chlorinated polyvinyl chloride resin and the like. According to the environment-friendly high-polymer board disclosed by the invention, blast furnace steel slag, pulverized fuel ash, flue gas desulfurization gypsum and other industrial solid wastes and cement are taken as main raw materials and are blended with wollastonite powder and slaked lime, so that the environment-friendly high-polymer board not only has the capabilities of reducing the pollution of emission of the industrial solid wastes to the environment and realizing heat insulation and heat preservation, but also has economic and social benefits of changing wastes into valuables. The environment-friendly high-polymer board can be used for effectively overcoming the defects of low-temperature embrittleness, high temperature flowing and the like after film formation, and meanwhile, has the advantages of relatively high elastic recovery rate, good stability, long storage time, fire resistance, flame retardance and the like. Polyurethane elastomer added to the board has excellent wear resistance and oil resistance, belongs to a polar polymer which can be organically combined with polypropylene, and has the capability of effectively improving the mechanical property of a polypropylene cable material; added fluororubber has the properties of high temperature resistance, oil resistance and the like; added other filler has the capability of enhancing other physical properties and processability of cables.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an environment-friendly plate material with high polymer oil resistance and high temperature resistance. Background technique [0002] Asphalt is an important building waterproof material, which is widely used because of its excellent waterproof performance and low price. Polymer-modified asphalt waterproofing membrane has become a building waterproof material that has attracted much attention because of its excellent high and low temperature performance. However, polymer-modified asphalt waterproofing membranes, like ordinary organic materials, are susceptible to aging due to factors such as ultraviolet light, heat, and oxygen, resulting in hardening and brittle waterproofing membranes, and rapid reduction in low-temperature flexibility. It is difficult to adapt to the cold shrinkage of the roof base layer and cracks occur, resulting in damage to the waterproof lay...

Problems solved by technology

Chinese patent CN102190957A proposes to add magnesium-aluminum-based layered double hydroxide to asphalt, and utilize the physical shielding effect of magnesium-aluminum-based layered double hydroxide on ultraviolet rays to improve the anti-ultraviolet aging ability of elastomer-modified asphalt, but asphalt is used In the process, in addition to the aging caused by ultraviolet light, thermal and oxygen aging will also occur under the action of heat and oxygen, and the effect of magnesium-aluminum-based layered double hydroxide on improving the thermal and oxygen aging resistance of asphalt is not obvious

In addition, when ultraviolet rays pass through the LDHs multi-level laminate, multi-level reflection and refraction will occur on the laminate interface, and the energy will also be weakened.
