Embodiment 1

[0017] The present invention proposes a kind of preparation method of continuous glass fiber rubber prepreg, comprises the steps:

[0018] S1. Surface modification of continuous glass fiber cloth: burn commercial glass fiber cloth at 400°C for 25 minutes to remove surface paraffin to obtain surface heat-treated glass fiber cloth a, and then mix 88% EtOH with 8% The H2O was made into an alcoholic aqueous solution. After adding a coupling agent and stirring for 4 minutes under magnetic stirring, the treatment solution b was prepared. Then, the glass fiber cloth a was soaked in the treatment solution b for 10 minutes until it was completely saturated, and then dried at 85°C for 22 hours. , that is, a surface-modified glass fiber cloth is obtained;

[0019] S2. Preparation of natural rubber glue: dissolve natural rubber in two or more mixed solvents with a solid content of 25%, stir at 900r / min for 1.5h under the action of mechanical stirring until a stable and uniform glue is for...

Abstract

The invention discloses a preparation method for continuous glass fiber rubber prepreg. The preparation method comprises the following steps that commercialized glass fiber cloth is combusted for 30 min at 450 DEG C to prepare glass fiber cloth a with the surface subjected to heat treatment; an alcohol-water solution of a certain concentration is prepared, and a coupling agent is added under magnetic stirring to be uniformly stirred to prepare treating fluid b; the glass fiber cloth a is immersed into the treating fluid b till being fully soaked; natural rubber is dissolved into two or more mixed solvents according to a certain solid content and stirred under the effect of mechanical stirring till a stable and uniform glue solution is formed to obtain a natural rubber glue solution; the surface-modified glass fiber cloth is orderly spread out through a homemade prepreg machine and orderly arranged; the rotating speed of guide rollers is controlled, and under the effect of squeeze rollers, redundant glue solutions are scraped and recycled; and the glass fiber cloth enters a drying oven to be dried and rolled to obtain continuous glass fiber rubber prepreg cloth. According to the preparation method, gradual heating is adopted for removing the solvents, preparation efficiency is improved, and unnecessary waste is avoided.

Description

technical field [0001] The invention relates to the technical field of glass fiber rubber, in particular to a preparation method of a continuous glass fiber rubber prepreg. Background technique [0002] Prepreg is a sheet or strip product made by impregnating one or several resin matrices in fibers in a certain way. It is a transition material in the preparation process of fiber composites. Reinforcement materials mainly include glass fiber, carbon fiber, boron fiber, Kevlar fiber, etc., and matrix materials mainly include natural rubber, epoxy resin, polyester resin, thermoplastic resin, etc. Fiber-reinforced resin-based composite materials have many characteristics such as high strength, hardness, corrosion resistance, wear resistance, impact resistance, light weight, and integrated structure and function, and have been widely used in aerospace, transportation, construction, shipbuilding and social various fields of life. With the demand and development of the market, pr...
