Embodiment Construction

[0009] Vinyl compound: 30 kg of styrene, 20 kg of butyl acrylate, 24 kg of methyl methacrylate, unsaturated organosilane: 20 kg of vinyltrimethoxyalkane, chain transfer agent (A-189), polymerization initiator: 4 kg, azobisiso Nitrile 2kg, xylene required.

[0010] Add the vinyl compound, unsaturated organosilane, chain transfer agent, and polymerization initiator in the formula dropwise to 100 g of xylene preheated at 90°C, and react for 10 hours to obtain a silicone-based vinyl copolymer with a number average molecular weight of 6,000.

[0011] The silicone-based ethylene copolymer prepared above is mixed with titanium dioxide at a solid ratio of 1:1, and dispersed by a ball mill to obtain a hundred-time paint.

[0012] Similarly, mix transparent iron oxide red with the above-mentioned copolymer according to the solid ratio of 100:30, and disperse it with a ball mill to make enamel.

[0013] The organosilicon group-containing vinyl copolymer has a hydrolyzable silicone group...

Abstract

The present invention relates to an ethylene copolymer coating containing organosilicone and a preparation method thereof. The ethylene copolymer coating is prepared by mixing the following ingredients in percentage by weight: vinyl compound: 30 % of styrene, 20 % of butyl acrylate, and 24 % of methyl methacrylate; unsaturated organosilane: 20 % of vinyltrimethoxysilane; and chain transfer agent (A-189): 4 % of polymerization initiator, 2 % of azobisisobutyronitrile and a defined amount of dimethylbenzene. The coating prepared from the ingredients is formed by organic substances. The end or side chain of the ethylene copolymer containing organosilicone is polymerized with water-disintegrable organosilicone. Therefore, the coating has polyvinyl characteristic, and weatherability, luster and adhesiveness of the coating are improved. No catalyst or solidified agent exists in the coating. The coating is capable of cross-linking by utilizing moisture, especially moisture in atmosphere to form a polybrochats structure under the atmospheric temperature. The coating can be applied according to a conventional application method and is dried at normal temperature. The coating is applicable to the application of aircraft structures, automobiles glass and the like and can be used as a sealant and for surface treatment of various inorganic substances.

Description

Technical field: [0001] The invention belongs to a coating and a preparation method thereof, in particular to an organic silicon-containing ethylene copolymer coating and a preparation method thereof. Background technique: [0002] The current coatings used for spraying metal surfaces have unsatisfactory spraying effects, and have defects such as poor appearance quality, easy division, easy wear damage, dull luster, etc., thereby affecting the appearance quality and appearance image of the metal plate. Invention content: [0003] The object of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a kind of ethylene copolymer coating containing organosilicon which is easy to spray, has good application effect, and has a bright surface after spraying. The technical scheme of the present invention is: coating weight ratio is composed of vinyl compound: 30% of styrene, 20% of butyl acrylate, 24% of methyl methacrylate, unsaturated ...
