Problems solved by technology

[0002] Composite resin has many outstanding features, such as good mechanical properties, good thermochemical stability, wide range of resin curing temperature, easy control of crosslinking density, no small molecule by-products during curing, so low shrinkage, It is widely used in the fields of adhesives, electronic instruments and aerospace materials. However, due to the high cross-linking density of pure epoxy resin cured products and the brittleness of the cured materials, its application in some high-tech fields is largely limited.

Abstract

The invention discloses an anti-aging toughing type epoxy resin composition. The anti-aging toughing type epoxy resin composition consists of the following raw materials in percentages by weight: 35-45 parts of dicyclopentadiene type epoxy resin, 8-12 parts of a diluent, 2.5-5 parts of lauryl sodium sulfate, 1-3 parts of fumed silica, 0.5-5 parts of propylene glycol methyl ether acetate and 0.3-2.5 parts of o-hydroxydiphenylketone. The anti-aging toughing type epoxy resin composition has excellent uvioresistant and aging-resistant properties. The product prepared from the epoxy resin composition can meet the requirement for outdoor long-time application.

Description

technical field [0001] The invention relates to the field of epoxy resin compositions, in particular to an anti-aging and toughening epoxy resin composition. Background technique [0002] Composite resin has many outstanding features, such as good mechanical properties, good thermochemical stability, wide range of resin curing temperature, easy control of crosslinking density, no small molecule by-products during curing, so low shrinkage, It is widely used in the fields of adhesives, electronic instruments and aerospace materials. However, due to the high cross-linking density of pure epoxy resin cured products and the brittleness of the cured materials, its application in some high-tech fields is largely limited. . Contents of the invention [0003] The main technical problem to be solved by the invention is that the anti-aging and toughening epoxy resin composition provided has excellent anti-ultraviolet and anti-aging properties, and the products made of the epoxy resi...
