Problems solved by technology

[0017] One of the technical problems to be solved by the present invention is to provide a solvent-based adhesive rich in thermoplastic elastomers, which can solve the common problem of existing adhesives that cannot solve the overall flexibility of the bonded assembly. The adhesive can take into account both viscosity and resilience, and can be well used in occasions that require high resilience

preparation example Construction

[0086] The present invention also discloses a preparation method of the solvent-based adhesive rich in thermoplastic elastomer, which includes the following steps:

[0087] Step 1) Mix the first thermoplastic elastomer styrenic block copolymer and mineral oil in a blade mixer for about 10 minutes or until the mineral oil is completely absorbed by the styrenic block copolymer, and set aside for later use;

[0088] Step 2) in the mixing chamber of the mixer with carbon dioxide gas protection, add the first solvent;

[0089] Step 3) Put all the remaining thermoplastic elastomers, tackifying resins, reinforcing resins, and additives into the mixing chamber described in step 2), start the propeller stirring device of the mixer to mix, and stir until each component is melted;

[0090] Step 4) Heat the mixing chamber to a temperature range of 100-120°C, stir for about 8 hours or until a transparent glue is obtained, then lower the temperature of the mixing chamber, and cool to close ...

Embodiment 1

[0103] The solvent-based adhesive of the present invention is prepared by adopting the following ingredients and mixing process, and each part of adhesive is prepared with a total of 40kg, and is mixed in a mixer with a propeller in the experiment under the protection of carbon dioxide gas. The machine consists of an electric motor driven propeller, oil / electric heating jacket, temperature control device and a mixing chamber for a vessel of about 100 liters.

[0104] The composition of the solvent-based adhesive:

Abstract

The present invention relates to a solvent-based adhesive rich in thermoplastic elastomers, comprising 0.1%-27% by weight of styrenic block copolymers, 0.1%-6% by weight of polyolefin block copolymers, 0% to 25% by weight of mineral oil, 0% to 13% by weight of tackifying resin, 0% to 8% by weight of reinforcing resin, 0.01% by weight of additives, 7 to 86% by weight of The first solvent, the second solvent, the third solvent, the total solid content of the thermoplastic elastomer has been kept above 50.9% by weight without calculating the solvent; the present invention also provides the preparation method and application method of the adhesive, the prepared Adhesives can balance viscosity and resilience, and can be well used in occasions that require high resilience, mainly for bonding two or more styrene-based or polyolefin-based thermoplastic elastomer products.

Description

【Technical field】 [0001] The invention relates to a solvent-based adhesive and a preparation method thereof, belonging to the field of chemical materials. 【Background technique】 [0002] At present, science and technology are developing day by day and the complexity of commodities has increased significantly, thus promoting the progress and development of the adhesive industry. Solvent-based TPE-containing adhesives can be used in a wide range of application processes to bond a variety of substrates for a variety of purposes. For example, in the elastomer mattress production industry, the materials involved may be woven fabrics, non-woven fabrics, polymer films, polymer filaments, polymer blocks, and generally elastomeric combinations. The end product of these elastomer combinations, the most important requirement for hot melt adhesives is that the adhesion to each component should be strong and durable; it is equally important that the flexibility of the bonded components ...
