Electronic brace paper and manufacturing process thereof

The invention provides electronic bracing paper and a manufacturing process thereof, and the manufacturing process comprises the following steps: mixing 70-85wt% of unbleached sulfate softwood pulp and 15-30wt% of unbleached sulfate hardwood pulp, and then sequentially carrying out repulping, defibrination, pulping, pulp proportioning, sizing, net forming, composite squeezing, pre-drying, elastic squeezing and post-drying to obtain the electronic bracing paper, wherein pulp with the concentration of 25-30 wt% is adopted in the grinding step; in the pulping step, pulp with the concentration of 5-6.5 wt% is adopted, and a fiber swelling agent is added to assist the pulping; a water absorbent is added in the sizing process. According to the manufacturing method of the electronic brace paper used during processing in the electronic industry, the obtained product is uniform in fiber distribution, has good strength, elasticity and the like, is uniformly glued, does not have wire drawing, and can meet the packaging
