Insulated environment-friendly neoprene sealant and preparation method thereof

Abstract

The invention provides an insulated environment-friendly neoprene sealant and a preparation method thereof and relates to the technical field of production of neoprene sealants. The neoprene sealant is prepared from the following raw materials in parts by weight: 100-110 parts of neoprene, 10-14 parts of sodium hydroxide, 4-6 parts of zinc oxide, 4-6 parts of magnesium oxide, 130-140 parts of acetic ether, 22-24 parts of phenolic resins, 18-20 parts of calcium carbonate, 10-12 parts of ammonium chloride, 8-12 parts of white carbon black, 12-16 parts of mica powder, 6-10 parts of talcum powder,12-16 parts of alumina, 6-10 parts of beryllia, 150-170 parts of solvent oil, 2-4 parts of an anti-ageing agent and 2-4 parts of an accelerant. The defects of the prior art are overcome, the adhesiveness of the sealant can be effectively improved, the sealing property is excellent, the insulating property of the sealant can be effectively improved, and the condition that the sealant is conductiveso as to damage internal electronic components and other parts is avoided. Meanwhile, the sealant is prevented from being heated to melt after conduction, the safety is high, the adopted raw materials are environment-friendly and harmless, the preparation process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of neoprene sealant production, in particular to an insulating and environment-friendly neoprene sealant and a preparation method thereof. Background technique [0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the configuration gap and seal it. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. There are many types of sealants, and neoprene sealants are one of them. Neoprene sealant is mainly made of neoprene rubber as the main raw material, together with other auxiliary materials. Neoprene sealant is widely used in the sealing of construction, transportation, electronic instruments and parts. [0003] At present, the formula composition and production process of neoprene sealant are unreasonable, resulting in poor i...
