Abstract
The invention relates to PRTV durability anti-pollution flashover paint, which comprises the following components by part by weight: 40 to 50 parts of dihydric polydimethylsiloxane, 2 to 6 parts of nano Si02, 2 to 6 parts of cross-linking agent, 0.02 to 1 part of catalyst, 20 to 30 parts of aluminum hydroxide, 5 to 8 parts of decabromodiphenyl, 40 to 50 parts of solvent and 1 to 2 parts of pigment. The paint uses dihydric polydimethylsiloxane as base rubber and has the good properties of ageing resistance, corrosion resistance, water resistance, moisture prevention, no toxin, insulation, shake resistance, excellent simulation, demolding, extremely low contractibility rate and the like. Because nano Si02 is added to the paint, the weather fastness, the ultraviolet resistance and the ageing resistance of a coating are improved. The aluminum hydroxide and the decabromodiphenyl are used as excellent composite fire retardants for the paint, thereby remarkably enhancing the arc resistance of the paint and helping to increase the thickness of the coating. Therefore, inflaming retarding and ageing resistance become more stable.
Description
Technical field
The invention belongs to insulation compound, particularly relate to a kind of PRTV persistence antifouling flush paint.
Background technology
Ambient cure Zylox is affirmed by department of State Grid as the insulator dirt-proof coating, and has been formulated industry standard i.e. " power system is with ambient cure Zylox antifouling flush paint technical qualification " (DL/T627-2004).Can find out that from technical qualification the key technical indexes of PRTV persistence antifouling flush paint is hydrophobic nature, flame retardant resistance and stability to aging.
In the known technology of ambient cure Zylox, generally adopting hydroxy-terminated polysiloxane is major ingredient, and its content reaches 20-40%.
Yet, adopt the existing silicon rubber insulation coating meet the antifouling flush paint technical qualification to have still that sag resistance is relatively poor, thickness is owed uniform defective, particularly be unfavorable for the stable of fire-retardant and ageing-resistant performance than shallow layer.
Summary of the invention
The present invention exists still in order to solve in the known technology silicon rubber insulation coating that sag resistance is relatively poor, thickness is owed uniform technical problem, and discloses a kind of PRTV persistence antifouling flush paint.
PRTV persistence antifouling flush paint of the present invention comprises each component of following weight part:
Dialkyl polydimethylsiloxane 40-50; Nanometer Si0
22-6; Linking agent 2-6; Catalyzer 0.02-1; White lake 20-30; Decabromodiphenyl oxide 5-8; Solvent 40-50; Pigment 1-2.
Said dialkyl polydimethylsiloxane range of viscosities is 15000-40000cs
The invention has the beneficial effects as follows:
1, dialkyl polydimethylsiloxane is a kind of straight chain shape high-molecular weight organopolysiloxane synthetic materials, has ageing-resistant, corrosion-resistant as the basic glue of this coating; Anti-water is moistureproof, and is nontoxic, insulation; Antidetonation, excellent emulation property, release property and extremely low premium propertiess such as shrinking percentage.
2, dialkyl polydimethylsiloxane and nanometer Si0
2Combining makes this coating have good thixotropy, applies the coating thin and thick uniformity that the back forms, and weathering resistance, Ginkgo Biloba Leaf Extract and the resistance to deterioration of coating are improved.
3, white lake and decabromodiphenyl oxide are the good composite fire retardant of this coating property, have not only obviously improved the anti-electric-arc performance of this coating, also help to increase the thickness of coating, make fire-retardant more stable with ageing-resistant performance.
