Problems solved by technology

In order to meet the needs of interior decoration, environmentally friendly all-purpose adhesives with styrene-butadiene rubber (SBS glue) and triphenyl solvents have appeared on the market, as disclosed in Chinese patent ZL 02115077.X (publication date 2003.10.29, publication number CN1451709A) "Multipurpose Universal Decorative Adhesive", Chinese Patent ZL02115167.9 (publication date 2003.11.05, publication number CN1453325A) disclosed "high-viscosity SBS non-toxic universal decorative glue" and Chinese patent ZL200410037322.X (publication date 2005.01. 26. The "Environmentally Friendly Universal Adhesive and Its Production Method" disclosed by Publication No. CN1570006A) is a product made of SBS as the main component and processed with various mixed solvents such as ethyl acetate and solvent naphtha. Although it does not contain Triphenyl is relatively harmful, but the inherent flammability and explosiveness of solvent-based glue has not been really solved. The volatilization of organic solvents in glue will also cause environmental pollution, and the working environment has a strong smell, and organic solvents are also harmful to the human body. Harmful, easy to form occupational diseases, not conducive to the health of workers
[0004] There are also various water-based adhesives in the prior art, such as water-based adhesives such as vinyl acetate homopolymer emulsions and acrylate copolymer emulsions, but all of them can only meet part of the use requirements, and there are deficiencies in one way or another. There is also a lack of a water-based universal adhesive that is widely applicable and easy to use

Abstract

The invention discloses a water-based all purpose adhesive and the preparation method, which belongs to the field of water-based adhesive, the technical proposal is a copolymer emulsion of 120 to 300 portions of vinyl acetate, 15 to 50 portions of organic silicon monomer with unsaturated double bond, 60 to 150 portions of ethylene tertiary carbonate, 80 to 120 portions of butyl acrylate, 90 to 150 portions of iso-octyl acrylate, 5 to 15 portions of acrylic acid; the emulsion also comprises 20 to 80 portions of tackifying resin, 3 to 8 portions of sodium salt decocting mixture, 50 to 150 portions of plasticizer, 15 to 50 portions of polyvinyl alcohol, 2 to 8 portions of silane coupling agent, 8 to 12 portions of hydrochloric acid, 3 to 15 portions of anionic emulsifier and 3 to 12 portions of nonionic emulsifier. The preparation method is that the mixed monomer is dropped by the manner of emulsion polymerization, and should be completed in three to five hours; warming up to 85 to 95 DEG C to cure for 40 to 60 minutes; then discharging and filtering and packaging after cooling down to 45 to 35 DEG C. The water-based all purpose adhesive has the advantages of convenient use, wide applicability, and can be used for the manufacturing of furniture, luggage and construction decoration.

Description

technical field [0001] The present invention relates to a kind of water-based adhesive, more specifically, it relates to a kind of water-based all-purpose adhesive used in furniture, bag manufacturing, building decoration, and the invention also relates to the preparation method of this all-purpose adhesive. Background technique [0002] The universal adhesive we usually refer to refers to a type of solvent-based adhesive commonly used in the architectural decoration and hardware maintenance industries. It is named for its wide bonding range and ease of use. The main component of early universal glue is neoprene, which generally uses benzene, toluene, and xylene as solvents. It is yellow liquid and viscous (commonly known as yellow glue). Bonding of hard and soft materials such as metals. Because benzene, toluene, and xylene are harmful to the body, their use has been banned abroad, but they will not withdraw from the domestic interior decoration market in the short term. ...
