PS-ABS (polystyrene-acrylonitrile butadiene styrene) solvent type adhesive

Abstract

The invention relates to a PS-ABS (polystyrene-acrylonitrile butadiene styrene) solvent type adhesive. The PS-ABS solvent type adhesive is prepared from the following raw materials in parts by weight: 250-350 parts of PS resin, 40-60 parts of ABS resin and 600-700 parts of ethyl acetate. The PS-ABS resin co-mixing can greatly improve the hard and crisp performances of an adhesive layer, increase the range of applications of the adhesive disclosed by the invention and be used for adhering wood, ceramic, plastic, cloth, paper and other materials. According to the PS-ABS solvent type adhesive disclosed by the invention, the ethyl acetate is taken as a solvent, the toxicity is low, and the corrosion to a packaging material, namely a flexible aluminum pipe is small. The PS-ABS solvent type adhesive disclosed by the invention has the advantages of good adhesion with an adhered object, high strength, low toxicity, long preservation time, simplicity and convenience for use and the like.

Description

technical field

[0001] The invention relates to a PS-ABS solvent type adhesive. Background technique

[0002] PS is a thermoplastic resin that can be directly dissolved in solvents to make PS solvent-based adhesives. PS solvent-based adhesive is easy to use, fast in positioning, water-resistant and corrosion-resistant. However, PS solvent-based adhesives have the following disadvantages: PS is a non-polar substance, and its bonding ability with polar adherends is poor; PS resin is of average strength and brittle, and the adhesive layer is hard and brittle, which is prone to stress brittle cracking ; PS solvent-based adhesives often use low-cost toluene and xylene as solvents. These solvents are highly toxic and endanger human health; they are also corrosive to soft aluminum tubes, which is not conducive to long-term storage of adhesives. Contents of the invention

[0003] The technical problem to be solved in the present invention is to provide a PS-ABS solvent-based adh...

Examples

Embodiment 1

[0018] The preparation method is as follows: 250 parts of PS resin, 40 parts of ABS resin, and 670 parts of ethyl acetate are mixed and stirred evenly to obtain a transparent glue, which is packaged in a soft aluminum tube for use.

Embodiment 2

[0020] The preparation method is as follows: 280 parts of PS resin, 53 parts of ABS resin, and 630 parts of ethyl acetate are mixed and stirred evenly to obtain a transparent glue, which is packaged in soft aluminum tubes for use.

Embodiment 3

[0022] The preparation method is as follows: 300 parts of PS resin, 50 parts of ABS resin, and 650 parts of ethyl acetate are mixed and stirred evenly to obtain a transparent glue, which is packaged in soft aluminum tubes for use.
