Embodiment 1

[0017] A low-odor adhesive made from the following parts by weight:

[0018] 20 parts of chlorosulfonated polyethylene, 10 parts of acrylate monomer, 20 parts of epoxy methacrylate, 10 parts of cumene hydroperoxide, 10 parts of calcium carbonate whiskers, and 10 parts of hydroquinone.

[0019] A low-odor adhesive, the preparation process of which is:

[0020] Plasticize the chlorosulfonated polyethylene on the open kneading machine, thin pass it ten times, and release the sheet for later use; in the reaction kettle, add acrylate monomer, epoxy methacrylate, and chlorosulfonated polyethylene sheet, heat Control the temperature at 40°C, stir until the chlorosulfonated polyethylene is completely dissolved, stir for 2 hours, add cumene hydrogen peroxide and stir for 20 minutes after cooling to room temperature, and finally add calcium carbonate whiskers and hydroquinone and stir until uniformly dispersed, that is Can.

Abstract

The invention relates to a low-smell adhesive and a preparation method of the low-smell adhesive, and belongs to the technical field of daily chemical production. The adhesive is prepared from chlorosulfonated polyethylene, acrylic monomer, epoxy metacrylic acid ester, cumene hydroperoxide, calcium carbonate crystal whisker and hydroquinone. The preparation method comprises the following steps: plasticating chlorosulfonated polyethylene on an open mill; performing thin-passing on the chlorosulfonated polyethylene for ten times and slicing out; adding acrylic monomer, the epoxy metacrylic acid ester and the chlorosulfonated polyethylene into a reaction kettle; heating and stirring until the chlorosulfonated polyethylene is completely dissolved; cooling to be at a room temperature; adding cumene hydroperoxide for stirring; and finally, adding calcium carbonate crystal whisker and hydroquinone for stirring and dispersing uniformly. According to the adhesive, the acrylic monomer and the epoxy metacrylic acid ester are compounded, so that the adhesive has the advantages of the acrylic monomer and the epoxy metacrylic acid ester; the defects are overcome, the fragility problem of the epoxy metacrylic acid ester is solved, the adhesive is low in smell and is free of strong pungent odor on adhesion of leathers.

Description

technical field [0001] The invention relates to an adhesive and a manufacturing method thereof, in particular to a low-odor adhesive and a manufacturing method thereof, belonging to the technical field of daily chemical production. Background technique [0002] Humans began to use adhesives a long time ago, and it is a long process to trace the development of adhesives. More than 6,000 years ago, in order to bond stones, wood, etc. to make living tools, bricks and pottery, humans mixed water and glue to make adhesives. More than 4,000 years ago, raw lacquer was used as paint and adhesive to make utensils with both practical and artistic value. More than 3,000 years ago, humans used animal glue to make caulking sealants for wooden boats. More than 2,000 years ago, the ships sailing in the Mediterranean filled the ships with asphalt, ore, wood resin and other substances similar to adhesives to play the role of bonding and waterproofing. With the rapid development of economy ...
