Special wetting agent for reinforcing polyformaldehyde material by using basalt fibers, and preparation method thereof

Abstract

The invention discloses a special wetting agent for reinforcing a polyformaldehyde material by using basalt fibers, and a preparation method thereof, wherein the special wetting agent comprises, by weight, 40-60 parts of a film forming agent, 5-15 parts of a coupling agent, 1-5 parts of a lubricant, 10-20 parts of a modifier, and 30-50 parts of a solvent, and the modifier comprises a hypophosphite and an acid according to a mass ratio of 5-8:1-3. According to the present invention, through the modifier, the wetting is performed while the fiber surface is modified, such that the fiber surface roughness is increased and a large number of the active groups are grafted so as to improve the chemical bonding and mechanical riveting capability between the basalt fibers and the polyformaldehyde material, improve the compatibility between the basalt fibers and the polyformaldehyde material, and promote the promotion application of the basalt fibers in the polyformaldehyde material reinforcement field.

Description

technical field [0001] The invention relates to the field of basalt fiber sizing agent, in particular to a special sizing agent for polyoxymethylene material reinforced basalt fiber and a preparation method thereof. Background technique [0002] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, and it is one of the four high-performance fibers that will be developed in my country in the future. The basalt rock material composed of basalt is melted at high temperature and then prepared by spinning process. Basalt continuous fiber not only has good stability, but also has various excellent properties such as electrical insulation, corrosion resistance, combustion resistance, and high temperature resistance. Moreover, the production process of basalt fiber produces less waste and less environmental pollution. It can be directly transferred to the ecological environment without any harm, so it is a veritable green and environ...
