Novel table tennis bat base plate of basalt composite material

Abstract

The invention belongs to the technical field of table tennis bats, and particularly relates to a novel table tennis bat base plate of a basalt composite material. The novel table tennis bat base plate is mainly formed by processing multi-layer basalt fiber cloth through a technique of resin and rubber mixed liquid soaking and integral mold pressing, wherein the basalt fiber cloth is subjected to degreasing treatment before being soaked by resin and rubber mixed liquid. The basalt fiber cloth is firstly dried and degreased, a basalt fiber and a resin fiber are crosslinked through a combining bond through resin and rubber mixed liquid soaking to form relatively high tenacity and strength. After the table tennis bat base plate is processed, the whole table tennis bat is uniform in density; the force reaction speeds in various directions are the same; the novel table tennis bat base plate has relatively high stability, high strength and sufficient tenacity and also has excellent properties of electric insulating property, corrosion resistance, combustion resistance, high temperature resistance and the like; the service life of the table tennis bat is prolonged; meanwhile, the production cost is relatively low; the problems that a carbon fiber product is overhigh in price and the market share is over-low are solved; and the economic benefits are significant.

Description

technical field

[0001] The invention belongs to the technical field of table tennis rackets, and in particular relates to a novel table tennis racket bottom plate made of basalt composite material. Background technique

[0002] The table tennis rackets currently on the market are mainly solid wood rackets and carbon fiber rackets. The density of solid wood rackets is uneven due to the annual rings of wood, and the force response speed in each direction is slightly different, so that its elasticity is different. It is not determined by the way the athlete hits, there is a certain chance, even if the density of the composite board is as uniform as possible in all directions, there are still differences, and the cost of carbon fiber is too high, and imports are restricted; so a new type is needed Substitute products to meet market demand.

Embodiment 1

[0013] A new type of table tennis racket bottom plate made of basalt composite material, which is mainly processed by the process of multi-layer basalt fiber cloth soaked in resin mixture and molded as a whole. The resin mixture is prepared from the following raw materials in parts by weight: Shuangma 50 parts of modified phenolic resin, 35 parts of polyaryl acetylene resin, 0.5 part of benzotriazole, 7 parts of dialkyl diphenylamine, 8 parts of dodecyltrimethylammonium bromide, 2 parts of sodium fatty alcohol sulfate , 3 parts of potassium dichloroisocyanurate, 2 parts of fatty alcohol polyoxyethylene ether, 5 parts of zinc naphthenate, 4 parts of terephthaloyl chloride, 3 parts of the reaction product of quaternized ammonium chloride, polyamide wax powder 10 copies;

[0014] Wherein, the elongation at break of the resin mixed glue liquid matrix is ​​2.9-3.4%, the viscosity of the resin mixed glue liquid is 0.65-0.8Pa·s, and the mass percentage of the glue is 22.6%;
