Problems solved by technology

Although the toxicity problem has been solved to a certain extent, its production cost is still high, resulting in low market profits. The elimination and prohibition of the use of organic solvent-based spray glue is an inevitable trend in the development and improvement of the industry. Low toxicity, non-toxic, green and environmental protection are The development direction of spray glue
[0003] At present, the water-based neoprene spray glue on the market has defects such as low initial viscosity and slow drying speed, which cannot meet the requirements of production operations, and its application range is limited.

Abstract

The invention provides double-component aqueous neoprene spray glue, aiming at overcoming the defect of the existing aqueous neoprene spray glue. The double-component aqueous neoprene spray glue is characterized in that water is used as a solvent, the total volatile substances account for zero percentage, and the initial adhesive strength is high. The double-component aqueous neoprene spray glue is prepared by two steps: dissolving chloroprene rubber adhesive emulsion, polyurethane emulsion, polymethyl methacrylate emulsion, aqueous tackifying resin and zinc oxide to deionized water to obtain composite emulsion, and then adding aqueous tackifying resin, a stabilizer, a thixotropic agent and an ultraviolet light absorber to the composite emulsion to obtain the finished product of aqueous neoprene spray glue. In spraying, a water-based curing agent is added to the obtained finished product of aqueous neoprene spray glue and uniformly agitated, and the purpose of mixing and using is reached. The double-component aqueous neoprene spray glue has the advantages of being low in toxicity, green, environment-friendly, free of organic volatile substances, fast to dry, high in final adhesive strength, resistant to heat, convenient to construct, high in working efficiency, simple in production process, convenient in operation, and low in cost, and does not pollute the environment during production, so that the requirement on environment protection is met.

Description

technical field [0001] The invention relates to a spray glue in the field of decoration, which is a two-component water-based neoprene spray glue which is composed of a composite emulsion and a water-based curing agent and can be used in the fields of furniture, cloth art, decoration, light-weight materials and the like. Background technique [0002] Spray glue is a commonly used adhesive in the production of upholstered furniture, and is widely used in furniture, fabric, decoration, light-weight materials and other fields. At present, most of the spray glues used in China are organic solvent type. Solvent type spray glue is mainly composed of high polymer and solvent. The high polymer is generally chloroprene rubber (CR) and styrene copolymer (SBS), and the solvent is Butanone, toluene, chlorinated olefins, ethyl acetate, n-hexane. Solvent-based spray glue is volatile and causes waste and environmental pollution, and it is easy to cause damage to operators during use. More...
