Embodiment 1

[0029] The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system Materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.2 parts of isobutylpropylamino-POSS is dissolved in 197.8 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.

Embodiment 2

[0031] The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.4 parts of isobutylpropylamino-POSS are dissolved in 197.6 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.

Embodiment 3

[0033]The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system Materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.6 parts of isobutylpropylamino-POSS is dissolved in 197.4 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.

Abstract

The invention provides rubber anti-aging paint, and a preparation method and application thereof. The rubber anti-aging paint comprises the following ingredients in parts by weight with the total weight being 1000 parts: 200 to 350 parts of resin, 0.2 to 3.5 parts of auxiliary agents, 0 to 5 parts of POSS (polyhedral oligomeric silsesquioxane) and 641.5 to 799.8 parts of water. The paint can be used as a rubber coating. The rubber anti-aging paint provided by the invention comprises the POSS; the POSS can improve the intensity of the coating after film forming; through a cage-shaped three-dimensional structure, the self molecular dimension is larger; potential physical cross linking points are formed in the coating; the curing crosslinking of the paint is facilitated, so that the coating inside structure stability is improved; the sealing performance and the thermal stability of the coating are effectively increased. When the addition of the POSS is 0.2 percent, the improvement effect of the coating on the rubber is most obvious; the stretch intensity is 9.2 MPa; the break elongation rate is 620 percent.

Description

technical field [0001] The invention relates to a rubber anti-aging coating technology, in particular to a rubber anti-aging coating and a preparation method and application thereof, belonging to the field of coatings. Background technique [0002] Nitrile rubber is one of the seven major types of rubber in the world today. It is widely used in military, automobile, aerospace, shoemaking and other industries. It has excellent oil resistance, low temperature and high temperature resistance, wear resistance, and compression deformation resistance. Under the action of environmental factors such as ozone, ultraviolet light, and humidity, the surface structure of rubber products changes, showing aging phenomena such as loss of light, discoloration, hardening, chalking, and cracking, which leads to a decline in rubber performance. Usually, delaying the occurrence of rubber aging reaction is mainly achieved by adding various chemical substances, such as antioxidants, ultraviolet li...
