Problems solved by technology

[0004] However, FRP table tennis tables also have many deficiencies. For example, when used in the open air, they are prone to aging and deterioration due to the effects of solar radiation, high temperature, humid air, and wind and rain, causing the resin on the FRP surface to fall off, revealing white threads, and the surface gradually becomes rough.
In addition, FRP has an outstanding shortcoming, that is, once the surface is damaged, the damaged area will expand rapidly, and finally it will fail completely.
In addition, FRP products produce a large amount of organic volatiles in the process of processing, which affects the environment and human health.

Abstract

The invention discloses a polydicyclopentadiene composite material and a preparation method thereof, which belongs to the technical field of the forming of macromolecular material. The composite material mainly consists of raw materials such as polydicyclopentadiene, main catalyst and auxiliary catalyst in the ratio of (2000-4000): 1: (15-40), wherein the main catalyst is di[2,6 tert-butyl-4-methyl phenoxyl] dichloride tungsten, and the auxiliary catalyst is aluminium diethyl monochloride or triethyl aluminum. The polydicyclopentadiene composite material is excellent in comprehensive mechanical property, high in across measure and high in low-temperature impacting strength, the bending-resistant modulus is more than 1500MPa, the minimal notch impact strength is not less than 100J / , and the impact strength is maintained stable at the temperature of minus 40 to 115 DEG C. After being compounded with inorganic filler, the enhanced polydicyclopentadiene composite material is excellent in the comprehensive mechanical property on the basis of maintaining the original performance, the bending-resistant modulus can reach more than 2500MPa, and the hardness can be doubled.

Description

technical field [0001] The invention specifically relates to a polydicyclopentadiene composite material and a preparation method of the composite material, belonging to the technical field of polymer material molding. Background technique [0002] In my country, table tennis is deeply loved by the masses, and has become one of the most extensive sports, known as the national game. With the construction of new rural areas in my country, table tennis will become more popular, and the demand for table tennis equipment will increase. [0003] Traditional table tennis tables are made of wood or plywood, and are only suitable for indoor use because they are not weatherproof. In recent years, there has been a FRP table tennis table made of unsaturated polyester, which is not afraid of water and mildew, can be used outdoors, and has a low cost, especially suitable for rural areas. [0004] However, FRP table tennis tables also have many deficiencies. For example, when used in the ...
