Glass fiber screen cloth immersing glue solution for grinding wheel reinforcement and initial rinsing method

Abstract

The present invention discloses a glass fiber mesh fabric dip solution for reinforcement of grinding wheel and the dipping method, which belongs to the field of composite materials; wherein the dip solution is formed by mixing the industrial alcohol with the liquid phenolic resin, the solid content of which is larger than or equal to 65 percent. The mixing ratio between the liquid phenolic resin against the industrial alcohol ranges from 1:0.15 to 0.20. The presoaking method is realized by utilizing the conventional dipping machine and the specific operating steps are that the glass fiber mesh fabrics are delivered into a dipping groove through a fabric transportation drum and a fabric storage roller so as to be dipped by the dip solution arranged in the dipping groove; then the dipped glass fiber mesh fabrics go into the rubber pressing by a dandy roll and then are fed into an oven to be pre-cured; the dipped glass fiber mesh fabrics are pulled out by a traction device and are trimmed and rolled up after passing through a buffering fabric storage roller and a deviation-correcting device. Two kinds of raw materials are selected as the raw materials of the present invention, thus simplifying the confection process of the present invention; the hydrometer is used to measure and adjust the proportion of the dip solution, thus resulting in that the gum chicle content is effectively controlled and the quality of products is stable; the volatile quantity is lowered from originally 5 percent to 1.5 percent. The glass fiber mesh fabric dip solution for reinforcement of grinding wheel causes few contaminations to the environment, has low cost and is easy to be popularized and put into use.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a glass fiber mesh cloth dipping liquid and a dipping method for a grinding wheel reinforcement. Background technique [0002] In the prior art, after the weaving is completed, the glass fiber mesh cloth for reinforcing the grinding wheel cannot be directly applied to the grinding wheel, and must be dipped in glue before it can be put into use. The traditional dipping solution is made of solid phenolic resin, liquid phenolic resin, and then add an appropriate amount of epoxy resin and auxiliary components, such as plasticizers, colorants, etc., and completely dissolve in a solvent. The solvent can be ethanol, methanol Wait. This kind of dipping solution has many components, the preparation process is complicated, and the production efficiency is low. With 10 mesh 120g / m 2 Take mesh fabric as an example, the average output is 2000m 2 / day or so, and there are many volatiles,...
