Thermally vulcanized chloroprene mortar and preparation method thereof

Abstract

The invention provides heat curing chloroprene rubber adhesive cement and a preparation method of the heat curing chloroprene rubber adhesive cement. Raw materials of the adhesive cement comprise, by weight part, chloroprene rubber adhesive, domestic No. 1 smoke plastic, accelerating agents, indirect process zinc oxide, light magnesium oxide, anti-aging agents, antiscorching agents, white carbon black, thickening agents and mixed solvents. A traditional formula is improved, the toxic property is reduced, health of workers is protected, process operation performance in the production processing process is improved, preparation processes and operation steps are simplified, processing and making efficiency is improved, the adhesive force between the adhesive cement and the fabrics is improved for finished products, the impervious cement performance and the invariant color performance are met, the comprehensive performance of the adhesive cement is improved, the yield of the finished products is improved, the purposes of saving energy and reducing consumption are achieved, and economical cost is saved.

Description

technical field [0001] The invention relates to a kind of glue, in particular to a neoprene glue used for making hot-vulcanized molded footwear by lamination and a preparation method thereof. Background technique [0002] Neoprene glue is widely used in the production of shoes, and there have been the following problems for a long time: 1. Most of the neoprene glue uses organic solvents containing triphenyls (benzene, toluene, xylene). The toxicity is very high, and it is very harmful to the operators in the process of production and use. Although various protective measures have been taken, the harm to long-term contacts cannot be ignored; 2. Most neoprene glues are only suitable for cold bonding. Compression molding, there are few types that can be used for thermal vulcanization molding, but for the mixed rubber or molded parts (mainly used for oil-resistant rubber shoes) that use non-polar rubber such as neoprene and nitrile rubber as the main material Neoprene and other...

Problems solved by technology

[0002] Neoprene glue is widely used in the production of shoes, and there have been the following problems for a long time: 1. Most of the neoprene glue uses organic solvents containing triphenyls (benzene, toluene, xylene). The toxicity is very high, and it is very harmful to the operators in the process of production and use. Although various protective measures have been taken, the harm to long-term contacts cannot be ignored; 2. Most neoprene glues are only suitable for cold bonding. Compression molding, there are few types that can be used for thermal vulcanization molding, but for the mixed rubber or molded parts (mainly used for oil-resistant rubber shoes) that use non-polar rubber such as neoprene and nitrile rubber as the main material Neoprene and other non-polar rubbers must be used for bonding between them, and between them and the fabric, so as to ensure the adhesion index of the finished product; 3. The processability of neoprene mixing production is usually poor, and mixing The heat generated is large, the temperature rises quickly, it is easy to stick to the roller, and it is easy to burn; 4. Neoprene glue, especially the large-package finished neoprene glue purchased from outside, in the process of use, due to poor connection of production rhythm and other reasons Often it cannot be used up at one time, and the glue after parking is easily scrapped due to the excessive loss of burning time. Even if the vulcanization performance is normal, it usually leads to changes in concentration and high concentration, which makes it difficult to apply glue and easily causes glue damage. Slurry particles, such as using solvents, thinners, etc. for blending, can easily lead to low concentration, and it is easy to cause the inside of the fabric to see through after gluing, both of which will affect the appearance of the finished product and cause product quality loss
