Problems solved by technology

At present, the adhesives used in the filter industry have various defects and deficiencies in terms of high bonding strength, oil resistance, high temperature resistance, aging resistance and no stimulation: either they need to be heated to achieve curing strength; or The bonding strength cannot reach the service life of the product; either the brittleness is too high, it is easy to age and crack and cause the seal to fail; there is a pungent smell, etc... In short, it is inconvenient to use and the bonding effect is not ideal. It is used for filtration Device products will affect the quality and reputation of the product

Abstract

This invention discloses a bi-component adhesive and its preparation method thereof, which belongs to the field of adhesive technology. The adhesive contains a component A and a component B. The Component A therein contains components calculated in parts by weight as follows: 30-35 parts of amilan; 4-5.5 parts of benzyl alcohol; 100-132 parts of calcite in powder; 3-5.5 parts of coupling reagent. The Component B contains components calculated in parts by weight as follows: 80-100 parts of epoxy resin; 6-8.5 parts of benzyl alcohol; 18-29 parts of aluminum hydroxide and 4.4 parts of accelerant. The Component A and Component B are restored separately. When used, the ration of preparing Component A and Component B is 1-8:1. By screening adhesive components according to the component ratio, the preparation method effectively enhances the adhesive strength and endows the adhesive with the advantages of oil resistance, high temperature resistance and aging resistance which has effectively increased the service life of a filter. The technology of its preparation method is quite simple and the operation is quite convenient. The bi-component adhesive and the preparation method thereof are also clean and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a two-component adhesive and a preparation method thereof. Background technique [0002] Air filters, oil filters, and oil-gas separation filters are used to filter out impurities in the air and oil when the air compressor is in use, and to separate the oil-air mixture, so that the economic indicators, power indicators, An important accessory for the normal performance of reliability and emission indicators. With the improvement of the use efficiency of air compressors and the gradual implementation of emission regulations, the technological progress of air compressors has put forward new and higher requirements for filter products, which shows the importance of filters for air compressors. importance. When the product with unqualified original filtration efficiency is used, the dust and impurities entering the air compressor cannot be effectively filtered out, and the oil an...
