Example Embodiment

[0020] Example 1

[0021] 60g of maleic anhydride, phthalic anhydride, and propylene glycol with a molar ratio of 1:1:2.2 were subjected to melt polycondensation reaction, and 40g of styrene and 0.05g of p-benzene were added during the cooling process of the obtained unsaturated polyester prepolymer Diphenol, if mixed evenly, is unsaturated polyester resin.

[0022] 80g of the above unsaturated polyester resin, 9g of resorcinol bis(diphenyl phosphate), 5g of butanol etherified amino resin, 5g of methyl phenyl silicone resin (molar of organic group and silicon atom) The ratio is 1.1, the phenyl group accounts for 80% by mole percent of the organic group), 1g of dicumyl peroxide is stirred and mixed at 40°C for 0.5 hours, which is a halogen-free flame-retardant transparent unsaturated polyester insulating coating.

Example Embodiment

[0023] Example 2

[0024] Melt polycondensation reaction of 60g of maleic anhydride, phthalic anhydride, terephthalic acid, propylene glycol, and diethylene glycol with a molar ratio of 2:1:1:2.2:2 to obtain unsaturated polyester During the cooling process of the prepolymer, 40g vinyl toluene and 0.1g hydroquinone are added, and the mixture is evenly mixed to form an unsaturated polyester resin.

[0025] 50g of the above unsaturated polyester resin, 5g of oligomeric bisphenol A bis(diphenyl phosphate), 13g of butanol etherified amino resin, 30g of methyl phenyl silicone resin (organic group and silicon atom The molar ratio is 1.6, and the phenyl group accounts for 30% by mole percentage of organic groups.), 2g of 1,1-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane are stirred and mixed at 10°C 3 hours, it is halogen-free flame-retardant transparent unsaturated polyester insulating coating.

Example Embodiment

[0026] Example 3

[0027] 60g of maleic anhydride, phthalic anhydride, propylene glycol, and dipropylene glycol with a molar ratio of 1:1:1.2:1 were subjected to melt polycondensation reaction, and 40g of the obtained unsaturated polyester prepolymer was added during cooling. Methyl methacrylate, 0.2g hydroquinone, mixed evenly, becomes unsaturated polyester resin.

[0028] 66g of the above-mentioned unsaturated polyester resin, 15g of triphenyl phosphate, 5g of methanol etherified amino resin, 13.5g of methyl phenyl silicone resin (the molar ratio of organic groups to silicon atoms is 1.3, phenyl accounts for organic The base mole percentage is 50%), 0.5g parts of ethyl-3,3-bis(tert-butylperoxy)butyrate are stirred and mixed for 1 hour at 20°C, which is a halogen-free flame-retardant transparent unsaturated polyester Insulating paint.

Abstract

The invention discloses insulating paint of non-toxic fire retardant transparent unsaturated polyester and process for preparation. The paint is composed of the following components which are based on quanlified latex, including 50-80 parts of unsaturated polyester, 5-30 parts of methyl phenylsilicone resin, 5-30 parts of phosphate flame retardant, 5-30 parts of etherified amino resins and 0.5-4 parts of evocating agent. The insulating paint of non-toxic fire retardant transparent unsaturated polyester can be achieved by stirring and mixing the components for 0.5-3 hours under 10 DEG C to 40 DEG C. The external appearance of the insulating paint of fire retardant unsaturated polyester of the invention is transparent, the oxygen index of the solidifying product can be increased to 27% from 19%, and the vertical flame passes UL-94 V-0 level. The heat-resistant property and the weather ability of the paint are remarkably improved, and the paint can be used for the insulating treatment of various dry-type transformer windings and machine windings.

Description

technical field [0001] The invention relates to an unsaturated polyester coating, in particular to a halogen-free flame-retardant transparent unsaturated polyester insulating coating and a preparation method thereof. Background technique [0002] Unsaturated polyester resin (Unsaturated Polyester Resins, referred to as UPR) is a linear prepolymerization of glycol and unsaturated dibasic anhydride or unsaturated dicarboxylic acid, saturated dibasic anhydride or saturated dicarboxylic acid melt polycondensation Under the action of heating, light, high-energy radiation and initiators, it is copolymerized with vinyl monomers, cross-linked and cured into a thermosetting resin with a network structure. Unsaturated polyester resin has been favored by people for a long time because of its excellent formability and good comprehensive performance. It is widely used in the fields of construction, shipbuilding, automobile industry, chemical equipment, electronic appliances and sporting ...
