Problems solved by technology

[0009] The length and width of the buckle cloth are easy to change during processing or use. During the production process, there will be machine shrinkage, dyeing and finishing shrinkage, washing shrinkage and relaxation recovery shrinkage. The size of each production process changes. Dimensions are very unstable, it is very difficult to make a coated substrate
[0010] The gap between the loops of the buckle cloth is large, and the adhesive is very thin during the subsequent sand planting process. If the adhesive penetrates the bottom structure of the buckle, the buckle and the bottom structure will stick together, and it will not be able to play a role. The role of the buckle Product scrap
[0011] Due to the above unfavorable factors, the buckle cloth cannot be used as the base of the emery cloth so far.

Embodiment 1

[0044] 1. Choose ll0g / m 2 The buckle cloth is coated with a layer of polyacrylic acid containing 60% water on the non-buckle surface of the buckle cloth, and maintained on the setting machine at 170 ° C for 35 seconds to form a stiff layer to make the buckle cloth hard and loss of flexibility;

[0045] 2. Apply a mixture of nitrile latex, phenolic resin and thickener in a mass ratio of 7:2:1 to the buckle cloth that forms a stiff layer on one side, and coat the above materials with a sizing machine with a scraper. For the anti-seepage plugging layer, when the buckle cloth passes through the sizing roller, use the bottom surface of the lower scraper to scrape the waterproof adhesive on the bottom cloth, and at the same time, the adhesive fills the upper holes of the bottom cloth, and the bottom surface of the lower scraper scrapes Pulp protects the buckle on the front;

[0046] 3. Put the buckle cloth forming the anti-seepage plugging layer into the dryer, set the temperature...

Embodiment 2

[0050] 1. Choose ll0g / m 2 The buckle cloth is coated with a layer of polyacrylic acid containing 30% water on the non-buckle surface of the buckle cloth, and maintained on the setting machine at 160 ° C for 40 seconds to form a stiff layer to make the buckle cloth hard and loss of flexibility;

[0051] 2. Apply a mixture of styrene-butadiene latex, phenolic resin and thickener in a mass ratio of 7:2:1 to the buckle cloth that forms a stiff layer on one side, and coat the above materials with a sizing machine with a scraper to form For the anti-seepage plugging layer, when the buckle cloth passes through the sizing roller, use the bottom surface of the lower scraper to scrape the waterproof adhesive on the bottom cloth, and at the same time, the adhesive fills the upper holes of the bottom cloth, and the bottom surface of the lower scraper scrapes Pulp protects the buckle on the front;

Embodiment 3

[0056] 1. Use l20g / m 2 The buckle cloth is coated with a layer of polyacrylic acid containing 70% water on the non-buckle surface of the buckle cloth, and maintained on the setting machine at 180°C for 30s to form a stiff layer to make the buckle cloth hard and loss of flexibility;

[0057] 2. Apply a mixture of nitrile latex, phenolic resin and thickener in a mass ratio of 8:3:1 to the buckle cloth that forms a stiff layer on one side, and coat the above materials with a sizing machine with a scraper. For the anti-seepage plugging layer, when the buckle cloth passes through the sizing roller, use the bottom surface of the lower scraper to scrape the waterproof adhesive on the bottom cloth, and at the same time, the adhesive fills the upper holes of the bottom cloth, and the bottom surface of the lower scraper scrapes Pulp protects the buckle on the front;

Abstract

The invention discloses a fabric matrix of buckled abrasive cloth and a preparation method thereof, and belongs to the technical field of coated abrasive tool matrixes, and in particular relates to a fabric matrix of a coated abrasive tool. The matrix is characterized in that a stiffening agent is coated on a buckle-free surface of the buckled cloth (1), and a stiffening layer (2) is sized and formed on a sizing machine at 160-180 DEG C for 30-40s. A waterproof adhesive is adopted outside the stiffening layer (2). An anti-seepage leakage preventing layer (3) is formed through coating by a starching machine with a scraper which scraps the adhesive on bottom cloth and fills meshes on the bottom cloth. The scraper of the starching machine scraps slurry by a lower scraper in a bottom slurry-scraping manner, and then the bottom cloth is dried, pressed and polished. The common buckled cloth is manufactured to the stiffening, level and anti-seepage fabric matrix without damaging the buckling structure of the buckled cloth, so that the original matrix is omitted. A grinding material is directly binded on the fabric matrix of the buckled cloth to plant grit, so that the adhering and compounding steps are omitted.

Description

technical field [0001] A fabric base of buckle emery cloth and a preparation method thereof belong to the technical field of coated abrasive bases, and in particular relate to a fabric base of coated abrasives. Background technique [0002] In modern industry, a large number of pneumatic disc sandpaper machines are used in die-casting, musical instruments, automobiles, metal and plastic furniture, shipbuilding, and electronic products to polish various materials and eliminate small scratches and defects on the working surface. The pneumatic disc sandpaper machine is combined with a chemical fiber buckle disc sandpaper (cloth) for polishing. Chemical fiber buckle disc sandpaper (cloth), also known as back fleece disc sandpaper, is a conversion product of sandpaper (cloth), which is a product of ordinary sandpaper 5 (such as Figure 4 ) on the back of the chemical fiber buckle cloth 1 (such as Figure 5 ), the preparation of the ordinary sandpaper 5 of the complete process ne...
