A kind of SBS adhesive and preparation method thereof

Abstract

The invention discloses an SBS adhesive and a preparation method thereof. The SBS adhesive contains the following components in parts by mass: 9.9-10.5 parts of combined rubber, 57.1-63 parts of a mixed solvent, 1.2-1.8 parts of fuming sulfuric acid, 2.5-4.5 parts of butadiene styrene rubber, 21-21.9 parts of tackifying resin and 0.1-0.2 part of an anti-aging agent. The preparation method of the SBS adhesive comprises the following steps: (S1) completely dissolving the combined rubber into the mixed solvent at the normal temperature, so as to obtain mixed liquid; (S2) adding fuming sulfuric acid into the mixed liquid obtained in the step (S1) to generate sulfonation reaction for 2-4 hours, and adding a urea methanol solution; (S3) adding the butadiene styrene rubber SBR1502, the tackifyingresin and the anti-aging agent, stirring for uniformly dissolving, and filtering, so as to obtain the SBS adhesive. According to the preparation method, metal wire frames of a colored lamp and colored lamp cloth can be rapidly adhered in low-temperature and high-humidity environment, the bonding strength of the adhesive is reduced after the adhesion, the adhesion speed is low, and the SBS adhesive can meet the demands of the high-temperature environment and long-term exhibition and is low in toxin and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an SBS adhesive and a preparation method thereof. Background technique [0002] The Zigong Lantern Festival has a long history and has formed an artistic feature of large scale, diverse materials and rich connotations. "Zigong Lantern" has become a well-known brand in China's traditional lantern culture industry. The Zigong Lantern Industry has more than 40,000 employees all year round, and more than 80,000 people in the peak period. The annual output value exceeds 2 billion yuan. It has been exhibited in many countries and regions and more than 500 large and medium-sized cities in China, and the cumulative number of viewers has reached more than 1 billion times. [0003] The manual production process and expression techniques of Zigong lanterns include wire frame welding, butt welding modeling, color separation and pasting, internal light transmission, hand-painted p...

Problems solved by technology

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problem that the existing adhesives used in the production of colored lanterns have low viscosity, poor stickiness, fast reduction of adhesive strength after gluing, and pollution in low temperature and high humidity environments. To solve environmental problems, we provide a SBS adhesive, which can quickly bond the wire frame and the color lamp cloth of the colored lights under low temperature and high humidity environment, and the stickiness is enhanced. After bonding, the adhesive strength of the adhesive decreases slowly, which can Meet the needs of high-temperature environments and long-term exhibitions, and are low-toxic and environmentally friendly
