Embodiment approach 1

[0017] Embodiment 1: Use the latex paper produced by the French company ARJOWIGGINS as the substrate 1, and coat the substrate 1 with epoxy resin as the primer 2; then plant sand on the primer 2, and plant sand on the primer 2. Brown corundum abrasive 3 that has been calcined at high temperature; compound glue 4 is coated with phenolic resin binder mixed with nano-scale titanium dioxide after sand planting, and further wraps abrasive 3 to prevent it from falling off prematurely and affecting product grinding Lifespan; after regluing, rewind the sandpaper, and then cure the sandpaper, the curing temperature is 115°C, and the curing time is 8 hours; after curing, the sandpaper is flexed and humidified, and the assimilated sandpaper is sprayed with alcohol on the back to humidify Solution, the wetting solution is the aqueous solution that accounts for 10% by weight glycerin as hygroscopic agent and the polyethylene glycol that accounts for 0.5% as plasticizer, to ensure that sandp...

Embodiment approach 2

[0020] Embodiment 2: Use the latex paper produced by ARJOWIGGINS company in France as the substrate 1, and coat the polyurethane resin on the substrate 1 as the primer 2; then plant sand on the primer 2, and the sand planting is on the primer 2 Plant the brown corundum abrasive 3 that has been calcined at high temperature; the reglue 4 is to coat the phenolic resin binder mixed with nano-scale titanium dioxide and potassium fluoroborate after sand planting, and further wrap the abrasive 3 to prevent it from falling off prematurely It affects the grinding life of the product; after regluing, the sandpaper is rolled up, and then the sandpaper is cured, the curing temperature is 120 ° C, and the curing time is 6 hours; after curing, the sandpaper is flexed and humidified, and the back of the cured sandpaper Spray wine humidifying solution, humidifying solution is the aqueous solution that accounts for 15% by weight glycerin as hygroscopic agent and the polyethylene glycol that acc...

Embodiment approach 3

[0023] Embodiment 3: Use the latex paper produced by ARJOWIGGINS company in France as the substrate 1, and coat the polyurethane resin on the substrate 1 as the primer 2; then plant sand on the primer 2, and the sand planting is on the primer 2 Plant the brown corundum abrasive 3 that has been calcined at high temperature; the reglue 4 is to coat the phenolic resin binder mixed with nano-scale titanium dioxide, potassium fluoroborate, and sodium hexafluoroaluminate after sand planting, and further wrap the abrasive 3, so that It avoids premature falling off and affects the grinding life of the product; after regluing, the sandpaper is rolled up, and then the sandpaper is cured, the curing temperature is 125°C, and the curing time is 3 hours; after curing, the sandpaper is flexed and humidified, The backside of the solidified sandpaper is sprayed with a wetting solution, and the wetting solution is an aqueous solution of 25% by weight of glycerin as a hygroscopic agent and 2% of...

Abstract

The present invention relates to the field of grinding tools, in particular to a production method of a super-coating dry abrasive paper widely used to sand and polish the painted surfaces of furniture, musical instruments, etc. The production method of the super-coating dry abrasive paper of the present invention includes the following steps: substrate; primer; sand planting; composite glue; rolling; solidifying; flexing and humidifying; super coating; drying; rolling; cutting; packaging. The abrasive paper produced according to the production method has the advantages of sharpness, wear resistance, non-blocking and high strength, and the super coating of the soft basal body ensures that the abrasive paper can be slowly shed along with wood dust and abraded paint while sanding, thus greatly prolonging the service life of the abrasive paper.

Description

technical field [0001] The invention relates to the field of grinding tools, in particular to a production method of sandpaper widely used for grinding and polishing painted surfaces of furniture, musical instruments and the like. Background technique [0002] Sandpaper is widely used in the market because of its low cost, short process flow and high production efficiency. However, the grinding and polishing of painted surfaces in the furniture and musical instrument industries requires good anti-clogging sandpaper. Due to the certain viscosity of the paint, the existing sandpaper used for paint grinding is very easy to clog during the grinding process, and the clogging of the sandpaper will have no grinding force, lose the usability, and reduce the service life; in addition, the existing Sandpaper will change color when it is cured at high temperature during the production process, so the appearance of the product is monotonous. Contents of the invention [0003] The pu...
