Description
Technical Field
The invention relates to the technical field of coated abrasive product compound glue, in particular to super-leveling abrasive paper compound glue and a preparation method thereof.
Background
The sand paper is a common polishing tool in the coated abrasive industry, and has low price and convenient use. The common production flow of sandpaper is: base paper → primer coating → sand planting → predrying → laminating → drying → rewetting → finished product. The base glue and the compound glue are generally prepared by adding auxiliary materials such as filler and the like into synthetic resin. The abrasive paper using the method as the compound adhesive has poor leveling performance, the compound adhesive is easy to remain on an abrasive, the sharpness and roughness of the abrasive paper are seriously affected during use, the grinding efficiency is low when the metal or paint surface is polished, and scratches are easily caused, so that further improvement is needed.
CN110938399A relates to the technical field of grinding tools, in particular to a high-toughness phenolic resin binder for sand paper and a preparation method and an application method thereof. The high-toughness phenolic resin binder for the sand paper is prepared by mixing A, B, C and D, wherein the A component comprises phenolic resin, polyurethane and a multifunctional amine auxiliary agent, the B component is water, the C component comprises a silane coupling agent, a penetrating agent, a defoaming agent and a leveling agent, and the D component is a filler. Compared with the sand paper adhesive in the prior art, the high-toughness phenolic resin adhesive for sand paper only adopts water as a solvent and does not add any organic solvent, so that no organic solvent volatilizes in the curing process, and the pollution to the environment is reduced to the greatest extent. The preparation method has the characteristics of simple process, low production cost and suitability for large-scale production. The adhesive is made into sand paper for polishing, and the grinding test result shows that compared with the existing adhesive, the prepared sand paper has better flexibility and higher grinding efficiency. However, polyurethane has a poor leveling effect and is easily sticky, so that the polyurethane is difficult to be flatly laid on sandpaper and is easily left on abrasives, and the grinding amount and the roughness of the sandpaper are affected.
CN103692366A discloses a super-hydrophobic anti-blocking abrasive paper compound adhesive, which comprises four components of A, B, C and D; the component A consists of an adhesive and a solvent; the component B consists of a filler and a solvent; the third component consists of a slipping agent and a solvent; the component D consists of pigment and hydrophobic promoter. A preparation method of a super-hydrophobic anti-blocking sand paper compound adhesive comprises the steps of respectively preparing an adhesive and a filler according to the adhesive in a component A and the filler in a component B, respectively preparing the adhesive of the component A, the filler of the component B, a slipping agent of a component C and a solvent according to a weight ratio, respectively preparing a pigment of the component D and a hydrophobic accelerant according to a weight ratio, and finally mixing the four components according to the proportions of the component A, the component B, the component C and the component D and uniformly stirring. The invention improves the hydrophobic property of the sand paper, and leads the sand paper to have the characteristics of static resistance, blockage resistance and long service life. However, the addition of the slipping agent in the compound adhesive can reduce the strength of the compound adhesive and influence the sharpness of the abrasive paper, and the formula is only suitable for an oily compound adhesive system and is not suitable for aqueous compound adhesives.
Disclosure of Invention
Aiming at the existing defects, the invention provides the super-leveling sand paper compound adhesive and the preparation method thereof.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the super-leveling sand paper compound adhesive is prepared by mixing A, B, C, D four components in a weight ratio of 100: 1-40: 10-40: 0.3 to 3; the component A is 100 parts of aqueous adhesive; the component B is 1-40 parts of solvent; the component C is 10-40 parts of filler; the component D comprises 0.2-2 parts of polyether modified organic silicon and 0.1-1 part of hyperdispersant.
In the technical scheme, the water-based adhesive is one or more of phenolic resin, amino resin, epoxy resin or acrylic resin. The water-based adhesive disclosed by the invention is more environment-friendly in laminating and high in resin strength.
