Abstract
The invention discloses high-strength paper-based sand paper, which consists of base paper, an impregnating agent, a coating reagent and an under adhesive. The manufacturing method of the sand paper includes the following steps of unwinding, impregnating, coating, calendaring setting, winding, identification marking, under adhesive coating, high pressure electrostatic sand planting, pre-drying, glue coating, main drying, rolling, solidifying, unrolling and warehousing. The high-strength paper-based sand paper and the manufacturing method thereof have the advantages that the base paper which adopts the high-density material of 250g/m2 is high in tensile strength and the produced finished abrasive belt products can replace the similar abrasive cloth products; the sand paper is high in smoothness and can be used for manufacturing sand paper with ultra-fine particle sizes and the thinnest size can reach 1200 model; a new radiating wave type electrostatic sand planting technology is adopted with the voltage of 36 kv and frequency of 60Hz, and the gaps between compression rollers are kept between 1 and 6cm (micro adjustment can be made according to the particle sizes of the abrasive fillers that go through the compression rollers) so as to ensure the uniform distribution of the sand planting density; the cryolite is adopted as a filling agent in the under adhesive coating in order to ensure the thickness of the under adhesive and the bond force and to prevent adhesive penetration; the upper sands are evenly distributed, and the sand particles and work pieces are kept on the same plane and are attached closely in the grinding, and the consumption of the sand particles is synchronous and the ground wood work pieces have smooth surfaces; the antistatic function is provided.
