Problems solved by technology

However, the traditional water-resistant sandpaper uses solvent-based alkyd resin as an adhesive, and the waste gas generated in the production process pollutes the environment. At the same time, there are great safety hazards in the production, storage and transportation process.

specific Embodiment

[0018] Example 1, consists of six layers, from top to bottom are abrasive layer 1, adhesive layer 2, basic adhesive layer 3, sand surface treatment layer 4, sandpaper base paper layer 5 and waterproof treatment layer 6. The adhesive layer is a mixture of 100 parts of urea-formaldehyde resin, 6 parts of iron red and 0.5 part of ammonium chloride. The base adhesive layer is a mixture of 70 parts water-soluble acrylic resin, 30 parts amino resin, 5 parts flour and 5 parts iron red. The sand surface treatment layer is a mixture of 50 parts of nano-sized styrene-butadiene latex, 30 parts of modified starch solution, 20 parts of water and 1 part of penetrant JFS. The waterproof treatment layer is a mixture of 100 parts of nano-styrene-butadiene latex and 1 part of penetrant JFS.

[0019] Example 2, the same example 1, the difference is that the adhesive layer is a mixture of 90 parts of urea-formaldehyde resin, 8 parts of iron red and 2 parts of ammonium chloride. The base adhesiv...

Abstract

The invention relates to full-resin water-resistant paper, which is composed of six layers including an abrasive material layer, an adhesive layer, a basic adhesive layer, a sand surface processing layer, a sand paper base paper layer and a waterproof processing layer from top to bottom, wherein the adhesive layer is the mixture of a urea-formaldehyde resin, iron red and ammonium chloride; the basic adhesive layer is the mixture of a water-soluble acrylic resin, an amine resin, flour and iron red; the sand surface processing layer is the mixture of nanometer-sized styrene-butadiene latex, modified starch solution, water and a penetrating agent JFS; the waterproof processing layer is the mixture of the nanometer-sized styrene-butadiene latex and the penetrating agent JFS. The invention abandons a solvent alkyd resin and uses the water-soluble resin adhesive with environmental performance, such as the urea-formaldehyde resin, the water-soluble acrylic resin, the amine resin, the nanometer-sized styrene-butadiene latex and the like. As the invention completely uses the water-soluble resins, the environmental pollution is nearly zero. The full-resin water-resistant paper has no environmental pollution and has safe transport and use.

Description

technical field [0001] The invention relates to a water-resistant sandpaper. Background technique [0002] Water-resistant sandpaper is a traditional product in my country's coated abrasives industry. It has been widely accepted by the market, and the market usage is very large. It is suitable for grinding and fine processing of plastics, leather, precision instruments, ships, aircrafts, automobiles, national defense industry, machine tool machinery, etc., or for grinding the bottom layer and putty before spraying and baking paint, and can also be used for Fine grinding and polishing of bamboo and rattan products. However, the traditional water-resistant sandpaper uses solvent-based alkyd resin as an adhesive, and the waste gas generated during the production process pollutes the environment. At the same time, there are great safety hazards in the production, storage and transportation process. [0003] Traditional water-resistant sandpaper consists of six layers, from top...
