Insulating flame-retardant composite material for relay shell and preparation method of insulating flame-retardant composite material

Abstract

The invention provides an insulating flame-retardant composite material for a relay shell and a preparation method of the insulating flame-retardant composite material, and relates to the technical field of relay production. The composite material is prepared from the following raw materials in parts by weight: 45-55 parts of ABS resin, 15-20 parts of polycarbonate, 6-10 parts of poly(methyl methacrylate), 1.0-1.5 parts of nano magnesium oxide, 0.8-1.2 parts of a coupling agent, 5-7 parts of m-xylylenediamine, 2-4 parts of barium titanate, 4-6 parts of boron oxide, 6-8 parts of potassium bis(trifluoromethylsulfonyl)amide, 3-5 parts of polyazodiphenylene phenylphosphonate, 5-7 parts of butoxyethyl phosphate, 2-4 parts of tin oxide, 4-6 parts of ammonium octamolybdate, 2-4 parts of a plasticizer and 2-4 parts of a dispersant. The defects in the prior art are overcome, the insulating flame-retardant performance of the composite material can be effectively improved, the situation that a prepared relay shell leaks electricity, causes an electric shock or is even ignited is prevented, and the composite material is excellent in overall performance, high in safety and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of relay production, in particular to an insulating and flame-retardant composite material for a relay shell and a preparation method thereof. Background technique [0002] Relay (English name: relay) is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity (excitation quantity) meets the specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] At present, the formula c...

AI Technical Summary

Problems solved by technology

[0003] At present, the formula composition and production process of the relay shell are unreasonable, resulting in poor insulation and flame retardancy

In this way, during the normal use of the relay, electric leakage and electric shock are prone to occur, and at the same time, it is ignited under the influence of the external environment, and the safety is low.
