Abstract

The invention belongs to the field of adhesives, and particularly relates to an environment-friendly neoprene sealant and a preparation method thereof. The environment-friendly neoprene sealant comprises the following components: neoprene, filler, esters solvent, solvent oil, phytoextraction essential oil, softener and antioxygen, wherein the filler is a mixture made of one or more than two of talcum powder, light calcium carbonate, titanium dioxide, magnesium oxide, kaolin and blanc fixe; the esters solvent is the mixture made of one type or a mixture of more than two types of methyl acetate, acetic ether, n-butyl acetate, amyl acetate, isoamyl acetate, dimethyl carbonate, ethoxyethyl acetate and propylene glycol monomethyl ether acetate; and the solvent oil is one type or a mixture of more than two types of 6 # solvent oil, 90 # solvent oil, 120 # solvent oil and 200 # solvent oil. The environment-friendly neoprene sealant has the advantages of environmental protection, innocuity, pressure resistance, good sealing performance and high strippable property.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to an environment-friendly chloroprene sealing adhesive and a preparation method thereof. Background technique [0002] Neoprene sealant is a liquid sealant, also known as liquid sealing gasket and liquid gasket. It is a liquid static sealing material with good air tightness, high pressure resistance, oil resistance, water resistance, and mechanical shock resistance. , and has a wide temperature range. Among them, the semi-dry viscoelastic liquid sealant generally contains organic solvents. The film formed by the solvent volatilization after coating can permanently maintain viscoelasticity, pressure resistance, softness and easy disassembly. It is suitable for the automotive industry and machinery manufacturing. It is the most commonly used liquid sealant for sealing and waterproofing in the industry and construction industry. [0003] Neoprene is produced by emulsion polymerization of ch...
