CN104387968A - Flame retardant coating used for solar panels - Google Patents

Abstract

The invention relates to a coating used for solar panels and in particular relates to a flame retardant coating used for solar panels. The coating is prepared from the following raw materials in parts by weight: 15-35 parts of octamethyl cyclotetrasiloxane, 20-40 parts of ethylchlorosilane, 3-5 parts of methyl trifluoropropyl silicone oil, 1-6 parts of phenyl silicone oil, 0.3-1.5 parts of methyl ethyl ketone, 30-50 parts of asbestos powder and 5-10 parts of plasticizer. The flame retardant coating used for solar panels is resistant to high temperature, has good flame retardance and self-extinguishment and also maintains good electrical property, mechanical property and sealability.

Description

Fire-retardant solar panels coating

Technical field

The present invention relates to solar panels coating, especially fire-retardant solar panels coating.

Background technology

Due to the property of functional paint in fire-retardant and high-low temperature resistant, it is made to be widely used in fields such as aerospace, electric, power transmission and mechanical parts.The functional paint being applied to the aspects such as aerospace, electric and transmitting line at present often will work under the conditions such as high temperature, heating, high-voltage and electric discharge, to the thermotolerance of coating and flame-retardancy requirements also more and more higher, although common coating has flame retardant resistance and self-extinguishing, but when temperature is higher than 200 DEG C, use properties can be lost because of degradation with aging very soon.

Octamethylcyclotetrasiloxane 15 ~ 35 parts;

Ethyl chlorosilane 20 ~ 40 parts;

Methyl trifluoro propyl silicone oil 3 ~ 5 parts;

Phenyl silicone oil 1 ~ 6 part;

Methyl ethyl ketone 0.3 ~ 1.5 part;

Asbestos powder 30 ~ 50 parts;

5 ~ 10 parts, softening agent.

The preferred scheme of technique scheme is: obtained according to parts by weight by following raw material,

Octamethylcyclotetrasiloxane 25 parts;

Ethyl chlorosilane 30 parts;

Methyl trifluoro propyl silicone oil 4 parts;

Phenyl silicone oil 3 parts;

Methyl ethyl ketone 0.9 part;

Asbestos powder 42 parts;

7 parts, softening agent.

Due to the utilization of technique scheme, the present invention compared with prior art has following advantages and effect:

Fire-retardant solar panels coating of the present invention is high temperature resistant, flame retardant resistance and self-extinguishing good, maintain good electrical property, mechanical property and stopping property simultaneously.
