Preparation method of heat-resistant latex abrasive paper raw paper

Abstract

The invention discloses heat-resistant latex abrasive paper raw paper. The heat-resistant latex abrasive paper raw paper contains the following raw materials in parts by weight: 14 parts of a hydroxypolyacrylate emulsion, 5 parts of a cellulose acetate butyrate solution, 30 parts of bleached sulfate softwood pulp, 26 parts of broad-leaf blenched chemical wood pulp, 5 parts of a PVM/MA copolymer,6 parts of diacetone alcohol, 2.5 parts of an aqueous polyisocyanate solidifying agent, 5 parts of polyacrylamide, 14 parts of a 900-mesh environment-friendly pigment, 6 parts of talcum powder, 5 parts of an aid and 7 parts of a flame retardant. The invention further discloses a manufacturing method of the heat-resistant latex abrasive paper raw paper. The required materials are easily available,and the prepared heat-resistant latex abrasive paper raw paper has good bursting strength, folding strength, water absorption value and heat resistance.

Description

technical field [0001] The invention relates to pulping and papermaking technology, in particular to a method for preparing heat-resistant latex sandpaper base paper. Background technique [0002] Sandpaper is an abrasive tool made by adhering abrasive materials on a soft substrate with adhesives. The main raw materials of sandpaper are base paper, abrasive materials, and adhesives. In order to improve the grinding strength of the sandpaper, the base paper is not only required to be tough, but also wear-resistant and fold-resistant, and has good water resistance. [0003] Water-resistant sandpaper is mainly made of kraft paper after water-resistant impregnation treatment as water-resistant sandpaper base paper. At present, the production of water-resistant sandpaper continues to use the traditional alkyd varnish, alkyd enamel, amino resin paint and alkyd thinner as binders, and is manufactured by a suspended continuous production line. However, the water resistance and fle...

Problems solved by technology

[0004] The existing sandpaper base paper is not only too brittle, but also has low toughness, is not easy to withstand high temperature, and is very easy to be affected by high temperature. Especially in closed factories in summer, it is easy to be damaged and broken, which brings great inconvenience to actual work. Production The process is complicated. With the progress of society, higher requirements are put forward for the bursting strength, folding strength, water absorption value and heat resistance of the existing sandpaper base paper.
