Relay1 case material is based on plastics, because the relay1 case of metal quality easily produces electric leakage, the problem such as to puncture; But the problem that existing plastics relay1 case exists, and mechanical strength is not high, decay resistance is not good, electrical insulation properties is not enough, humidity resistance has much room for improvement, awaits improving or develop more excellent material further.
Summary of the invention
The object of the present invention is to provide a kind of composite relay1 case and preparation method thereof, existing plastics relay1 case can be overcome and there is the problem that mechanical strength is not high, decay resistance is not good, electrical insulation properties is not enough, humidity resistance has much room for improvement.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of composite relay1 case, comprise insulation flexible layer and metal rigidity layer, described insulation flexible layer is two-layer, and described metal rigidity layer is between two-layer described insulation flexible layer; Described insulation flexible layer comprises the composition of following ratio of quality and the number of copies: metaphenylene polyester 60 parts, talcum powder or mica powder 70 ~ 120 parts, polystyrene 60 parts, peroxidized t-butyl perbenzoate 1 ~ 4 part, 2 ~ 4 parts, magnesia, zinc stearate 6 parts.
As the composite relay1 case that the present invention improves further, described metal rigidity layer is silicon steel sheet, and the ratio of quality and the number of copies of described silicon steel sheet is 50 ~ 200 parts.
The preparation method of above-mentioned composite relay1 case comprises the steps:
(1) by metaphenylene polyester 60 parts, talcum powder or mica powder 70 ~ 120 parts, polystyrene 60 parts, peroxidized t-butyl perbenzoate 1 ~ 4 part, 2 ~ 4 parts, magnesia, zinc stearate 6 parts, uniform pasty mixture is made with high speed crushing, stirring equipment;
(2) pasty mixture that step (1) obtains evenly is coated on the both sides of stamping metal rigidity layer, obtains composite relay1 case semi-finished product;
(3) composite semi-finished products of step (2) is dried at least 24 hours as in the environment of 40 ~ 50 DEG C, composite relay1 case finished product can be obtained.
Composite relay1 case provided by the present invention, adopts the two-layer insulation flexible layer of clamping metal rigidity layer to make, therefore has higher mechanical strength, can bear certain deformation simultaneously; Efficiently solve the deficiency existing for conventional plastic relay1 case, have good electric property and decay resistance, insulating properties is high, and moisture effect is good, and can effectively prevent electric leakage accident from occurring, security performance is high, and long service life, applied widely.
