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:
The invention belongs to a kind of coating and preparation method thereof. be particularly related to a kind of organosilyl ethylene copolymer coating and preparation method thereof that contains.
Background technology:
The present coating that is used for the surface, metallize, the effect of spraying is undesirable, has defectives such as poor, the easy stroke part of visual appearance, wound easy to wear, gloss dimness, thereby has influenced the visual appearance and the image appearance of metal sheet.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and a kind of spraying that is easy to is provided, and scribble effect is good, and sprays the organosilyl ethylene copolymer coating that contains of rear surface light.Technical scheme of the present invention is: the coating weight ratio consists of vinyl compound: vinylbenzene 30%, butyl acrylate 20%, methyl methacrylate 24%, unsaturated organosilicon alkane: vinyl trimethoxy alkane 20%, chain-transfer agent (A-189) polymerization starter: 4%, Diisopropyl azodicarboxylate 2%, the dimethylbenzene requirement.
With the vinyl compound in the prescription, unsaturated organosilicon alkane, chain-transfer agent, polymerization starter are added drop-wise in the 100g dimethylbenzene of 90 ℃ of preheatings, and reaction 10h gets number-average molecular weight 6000 and must contain organic silica-based vinyl copolymer.
Sneak into titanium dioxide with the above-mentioned organic silica-based vinyl copolymer that contains that makes in 1: 1 ratio of solids constituent, get lacquer hundred times with the ball mill decentralized system.
Equally, transparent iron oxide red with above-mentioned multipolymer by 100: 30 mixed of solids constituent, disperse to make enamel paint with ball mill.
Advantage of the present invention is:
1, because the selected raw material of this product is an organic compound, do not contain heavy metal, nontoxic pollution-free.2, the rich texture of paint film, friction can not produce static, and good water tolerance, elasticity, snappiness, chemical resistant properties, wearability are arranged.Product contains 60% admittedly, and hiding rare height, surface covered are big, and unit usage quantity relative cost is low.3, being applicable to the metallic surface spraying, is that safe antistatic protection is with coating with lacquer.
Embodiment:
Vinyl compound: vinylbenzene 30kg, butyl acrylate 20kg, methyl methacrylate 24kg, unsaturated organosilicon alkane: vinyl trimethoxy alkane 20kg, chain-transfer agent (A-189) polymerization starter: 4kg, Diisopropyl azodicarboxylate 2kg, dimethylbenzene requirement.
With the vinyl compound in the prescription, unsaturated organosilicon alkane, chain-transfer agent, polymerization starter are added drop-wise in the 100g dimethylbenzene of 90 ℃ of preheatings, and reaction 10h gets number-average molecular weight 6000 and must contain organic silica-based vinyl copolymer.
Sneak into titanium dioxide with the above-mentioned organic silica-based vinyl copolymer that contains that makes in 1: 1 ratio of solids constituent, get lacquer hundred times with the ball mill decentralized system.
Equally, transparent iron oxide red with above-mentioned multipolymer by 100: 30 mixed of solids constituent, disperse to make enamel paint with ball mill.
This contains organic silica-based vinyl copolymer, endways or have water-disintegrable organic silica-basedly on the side chain, therefore, the ethylene-based polymer characteristic is arranged, and weathering resistance and gloss, tack also is improved.Catalyst-free or solidifying agent exist, and form fine and close reticulated structure according to the particularly atmospheric moisture cold cross-linking of moisture.
Above Pei Fang coating property:
Gloss (%) 90
Pencil hardness F
Stability in storage:
Initial viscosity Pa.s 0.25
50 ℃ of 3 week back Pa.s 0.6
Anti-toluene: good
Anti-thinner: good
25 ℃ of times of pot-life to skinning
Can be by the construction of coating conventional method, the Air drying of filming.
Can be used for the aircraft system thing, applications such as automobile, glass.Also can show processing as sealing agent and various inorganics.
