Publication No. CN101428404A Chinese Patent Application for Consolidated Abrasive Grinding Polishing Pad and Preparation Method thereof discloses a consolidating abrasive polishing pad. Small, affecting service life
The Chinese patent with the publication number CN101817172A based on thermally induced solidified abrasive polishing pads and its preparation method discloses a preparation process for thermally induced solidified abrasive pads, but the preparation of such abrasive pads is mainly carried out in an oven. Heated and baked, the efficiency of this method is low, and it is easy to cause uneven distribution of solid materials inside the prepared grinding pad, and pores are prone to appear in the grinding pad, with low density and poor mechanical strength, which affects its own mechanical properties. Performance and pad life

Embodiment 1

[0049] The thermosetting resin polishing pad has a structure such as figure 1 shown. It is manufactured by the following method: Weigh 100 grams of diamond abrasives with a particle size of 40 to 50 microns and 540 grams of silicon carbide with a particle size of 320 mesh (also can be replaced by silicon dioxide and aluminum oxide abrasives), 180 grams Particle size is 400 mesh copper powder (can also be replaced by iron powder, silver powder, aluminum powder, nickel powder, lead powder, titanium powder, zinc powder, tin powder), 30 grams of particle size is 8000 mesh graphite (also can be replaced by carbon black , molybdenum disulfide, replaced by cryolite), 180 grams of polyurethane acrylate (also can use bisphenol A epoxy acrylate, novolac epoxy acrylate ethylamine modified epoxy acrylic acid, utilize oleic acid, linoleic acid to carry out Chain-modified long aliphatic epoxy acrylate, polyester acrylate, polyether acrylate or acrylated polyacrylate instead), 8 grams of az...

Embodiment 2

[0056] Increase the copper powder content in Example 1 to 300 grams, weigh 500 grams of silicon carbide with a particle size of 320 mesh, and other compositions are the same as the preparation process, see Table 2, which shows the composition and the mass percentage of each component. The grinding pad prepared by the above method has a higher density, and it can be seen from the cross section of the grinding pad that the pores in the grinding pad are less and denser; the produced grinding pad does not have delamination. It can also be found in the experiment of grinding crystal hanging chains with the fully automatic crystal grinding equipment produced by Hangzhou Fuyang Mihong Machinery Co., Ltd. During the grinding process, the grinding pad will have a small amount of decomposed odor of the resin matrix, and there will also be a small amount of smoke. The average wear amount of grinding once is 4.06um.

[0058]

Embodiment 3

[0060] The copper powder content in Example 1 was increased to 600 grams, and 380 grams of silicon carbide with a particle size of 320 mesh was weighed. The other compositions were the same as the preparation process. See Table 3, which shows the composition and the mass percentage of each component. The grinding pad prepared by the above method has a relatively high density. As can be seen from the cross-section of the grinding pad, the pores in the grinding pad are less and denser; The solid material distribution is relatively uniform. It can also be found in the experiment of grinding crystal hanging chains with the fully automatic crystal grinding equipment produced by Hangzhou Fuyang Mihong Machinery Co., Ltd. During the grinding process, the grinding pad will have a small amount of decomposed odor of the resin matrix, and there will also be a small amount of smoke. The average wear amount of one grinding is 3.00um.

Abstract

The embodiment of the invention discloses a thermosetting resin grinding pad and a preparation method thereof. The thermosetting resin grinding pad comprises a diamond, a grinding material and a resin base body and contains the following components in percentage by mass of: 4 to 7 percent of diamond with the particle size being between 40 and 50 microns, 9 to 40 percent of grinding material with the particle size being between 20 and 70 microns, 10 to 55 percent of metal powder with the particle size being between 20 and 70 microns, 10 to 60 percent of polyacrylic prepolymer, 0.1 to 1 percent of radical / anion / oxidation-reduction thermal initiator, 0 to 0.7 percent of metal compound / tertiary amine / quaternary amine promote accelerator, 0.5 to 5 percent of antifriction composition, 0 to 4 percent of grinding material surface modifier and dispersing agent, 0 to 20 percent of system crosslinking density adjustment additive and 5 to 40 percent of acyclic acid esterification reactive diluent. According to the thermosetting resin grinding pad, the density, the mechanical strength and the abrasion resistance of the thermosetting resin grinding pad are improved.

Description

technical field [0001] The invention belongs to the technical field of grinding, and in particular relates to a thermosetting resin grinding pad and a preparation method thereof. Background technique [0002] Crystal (decorative glass) is widely used in daily life such as lamps and clothing, while optical glass is a key component of optical instruments and household digital products. In the global industrial adjustment, China undertakes most of the world's production and processing of crystal and optical glass. The crystal glass industry in Pujiang, known as the "Crystal Glass Capital of China", has become one of the three pillar industries in Pujiang after 25 years of development. By the end of 2011, the industry's output value exceeded 30 billion yuan, there were more than 23,000 production and processing sites, and 15 enterprises with an output value exceeding 100 million yuan. There are tens of thousands of products in seven series including lighting pendants, lamps, h...
