Rubber toughened SBS aldehyde removed all-purpose adhesive and preparation method thereof

Abstract

The invention relates to a rubber-toughened SBS formaldehyde-free universal adhesive and the preparation method thereof. The rubber-toughened SBS formaldehyde-free universal adhesive is characterized in that the adhesive is composed of linear butadiene-styrene thermoplastic elastomer 3% to 5%, star-shaped butadiene-styrene thermoplastic elastomer 7% to 9%, styrene-butadiene rubber 2.7% to 3.7%, petroleum resin 20.8% to 24.8%, formaldehyde-removing additive 1.4% to 2.6%, antioxidant 1.2% to 1.8%, petroleum ether 37% to 43%, oil solvent 16.5% to 19.5% and essence 0.4% to 0.6%. The preparation method comprises the following steps: (1) weighting the above materials according to the ratio; (2) adding styrene-butadiene rubber in the step (1) into a mixing roll machine for plasticizing, thin-passing and discharging sheets, adding the sheet material into a vertical high-speed stirring kettle, adding the oil solvent in the step (1) into the high-speed stirring kettle, dissolving, and stirring until the sheet material is dissolved completely to obtain the semi-product; and (3) respectively adding the residual material components into the stirring kettle implementing step (2), stirring and dissolving to obtain the final product. The rubber-toughened SBS formaldehyde-free universal adhesive can remove free formaldehyde released from boards and has the remarkable effects on protecting environment and maintaining human health during house decoration.

Description

technical field [0001] The invention relates to an adhesive, in particular to a rubber-toughened SBS aldehyde-removing universal adhesive and a preparation method thereof. It belongs to the technical field of chemical products. Background technique [0002] All-purpose adhesive is a multi-purpose solvent-based synthetic adhesive. Because the universal adhesive has many advantages such as high initial adhesion, room temperature curing, high bonding strength, wide range of uses, and convenient use, it has developed rapidly and is widely used in aviation, automobiles, construction, shoemaking, furniture, machinery, leather goods, Electrical appliances, transportation, shipbuilding, arts and crafts and other fields. At present, there are two main types of universal glue: one is based on rapidly crystallizing neoprene rubber, and the other is based on SBS (styrene-butadiene thermoplastic elastomer). In addition to neoprene, resin and other components, neoprene adhesives often ...

Problems solved by technology

[0005] The first object of the present invention is to overcome the shortcomings of existing adhesives, such as high content of harmful substances, poor adhesion, and lack of aldehyde removal function, to provide a rubber-toughened SBS aldehyde-removing universal adhesive. Low substance content, better adhesion, and at the same time, it can remove free formaldehyde released from the board, and play a role in purifying indoor air
