Problems solved by technology

[0009] 7. 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 will occur. The change means that the size is very unstable, and it is very difficult to make a coated substrate
[0010] 8. There is a large gap between the loops of the buckle cloth, 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 work. The product is scrapped due to the action of the buckle
[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 with a water content of 60% 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 temper...

Abstract

The invention discloses a fabric substrate of hasp abrasive cloth and a preparation method of the fabric matrix, belongs to the technical field of coated abrasive tool substrates, and particularly relates to a fabric substrate of a coated abrasive tool. The method is characterized by comprising the following steps of coating a layer of stiffening agent on the hasp-free surface of the hasp cloth, maintaining 25-35-second setting on a setting machine under the condition that the temperature is 160-180 DEG C to form a stiffening layer, adopting a waterproof adhesive outside the stiffening layer,forming an impermeable plugging layer by using a sizing machine with a scraper for coating, scraping the adhesive on base cloth to be flat by using the scraper, meanwhile, filling and leveling up meshes in the base cloth, and adopting the scraper of the sizing machine and a lower scraper to carry out slurry scraping, adopting a bottom surface slurry scraping mode, and performing drying and calendaring to obtain the substrate. According to the fabric substrate of the hasp abrasive cloth and the preparation method of the fabric substrate, common hasp cloth is made into the fabric substrate witha stiff, flat and impermeable surface. The hasp structure of the hasp cloth is not damaged, an original substrate is omitted, the abrasive is directly bonded to the fabric substrate of the hasp clothfor sand planting, and the bonding and compounding process is 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] 1. In modern industry, a large number of pneumatic disc sandpaper machines are used to polish various materials in die-casting, musical instruments, automobiles, hardware and plastic furniture, shipbuilding, and electronic products to 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 velvet disc sandpaper, is a conversion product of sandpaper (cloth), which is added to ordinary sandpaper (such as Figure 4 ) on the back of the chemical fiber buckle cloth (such as Figure 5 ), the preparation of ordinary sandpaper with a complete process needs to be carr...
