AI Technical Summary

Problems solved by technology

However, quite a lot of UV monomers or oligomers are still harmful to the operators, and the curing must have UV curing equipment
Due to the advancement of environmental protection, thermosetting peelable adhesives have gradually abandoned phthalate plasticizers and adopted environmentally friendly plasticizers, but the general requirements for curing are 120°C-150°C, 20min-60min, and there is energy consumption The shortcomings of high and low efficiency also require heating equipment to meet production requirements
The traditional self-drying peelable adhesive has been criticized by people because it contains a large amount of volatile solvents. After all, the evaporation of a large amount of organic solvents is very harmful to the health of operators and the working environment.

Abstract

The invention provides air-drying packaging protection peelable blue glue which comprises, by weight, 100 parts of thermoplastic elastomer, 0-10 parts of chloroprene rubber, 10-20 parts of tackifyingresin, 60-100 parts of environment-friendly solvent, 1-3 parts of flatting agent, 3-5 parts of defoamer and 1-5 parts of pigment. The invention puts forward a novel packaging protection method, and the air-drying packaging protection peelable blue glue can be used for packaging protection of special-shaped members and overcomes the defects of conventional packaging protection means. The packagingprotection method is simple in construction, a protection film is high in toughness, surface scratching can be avoided, and the protection film is easy to remove without residue.

Description

technical field [0001] The invention belongs to the technical field of peelable glue, and in particular relates to a self-drying peelable blue glue for packaging protection and a preparation method thereof. Background technique [0002] At present, OPP, PET, PVC and other film materials are generally used for the surface packaging protection of articles. Adhesive can be attached to the surface of the item. These protection methods all have certain disadvantages: the winding protection method can be used for the protection of special-shaped parts, but it is not beautiful enough and does not conform to the modern packaging concept; both electrostatic adsorption and self-adhesive surface bonding require the protection surface to be flat, if When there are hollows, grooves, protrusions, etc. on the protective surface, it will not be able to play a protective role; if the item is irregularly shaped and the protective surface has hollows, grooves, or protrusions, etc., the conven...
