Problems solved by technology

[0003] The Chinese patent with publication number 106497464A discloses an anti-wear and anti-aging SBS adhesive, which consists of the following components: 15-40 parts of SBS, 5-12 parts of acrylic resin, 1-3 parts of epoxy modified phenolic resin, methyl ethyl ketone 0.1-0.5 parts of oxime, 3-5 parts of nano fumed silica, 8-10 parts of rutile titanium dioxide, 0.5-4 parts of silane coupling agent, a mixture of ethyl acrylate and ethyl acetate at a weight ratio of 2:1 38-45 parts of solvent, the SBS adhesive has good yellowing resistance, but its elongation at break and tensile shear strength are poor, which cannot meet the needs of practical applications
[0004] The Chinese patent whose publication number is 105153986 A discloses a polyurethane modified SBS adhesive, which is modified by a terminal NCO-based polyurethane prepolymer to enhance the elongation at break and tensile shear strength of the adhesive, but its elongation at break The improvement of elongation and tensile shear strength is not obvious, and it still needs to be further improved to enhance exercise elongation and tensile shear strength. In addition, the polyurethane modified SBS adhesive in this patent cannot improve its yellowing resistance

Embodiment Construction

[0027] The following examples are provided below to specifically describe the present invention. It is necessary to point out that the following examples are only used to further illustrate the present invention, and cannot be interpreted as limiting the protection scope of the present invention. Some non-essential improvements or adjustments made by the embodiments to the present invention still belong to the protection scope of the present invention.

[0028] The preparation of SBS adhesive in embodiment 1-7 and comparative example 1-2:

[0029] According to the formula in Table 1, first add the solvent to the reaction kettle with a temperature of 14-20°C, and then add thermoplastic styrene-butadiene rubber, tackifying resin, silane coupling agent, calcium-containing compound, iron-containing compound and anti-aging agent to the reaction kettle in sequence And stir for 2-3 hours until uniform, then pour out and filter to obtain the SBS adhesive.

[0030] Wherein, the presen...

Abstract

The invention discloses an SBS (styrene butadiene styrene block copolymer) adhesive which comprises the following ingredients in parts by weight: 25-30 parts of thermoplastic styrene-butadiene rubber,20-25 parts of tackifying resin, 0.2-3 parts of a silane coupling agent, 0.2-3 parts of an anti-aging agent and 40-50 parts of a solvent, wherein based on the total weight of the SBS adhesive, the weight content of an element calcium is 5-50ppm, the weight content of an element iron is 40-200ppm, the element calcium is derived from calcium-containing compounds, and the element iron is derived from iron-containing compounds. The SBS adhesive disclosed by the invention has obviously improved elongation at break and tensile shear strength and good resistance to yellowing.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an SBS adhesive and a preparation method thereof.
