Problems solved by technology

However, none of these studies mentioned research on antifreeze performance and low-temperature storage stability, so the application of corresponding products in low-temperature environments will also be limited
[0004] In addition, the currently commercially available neoprene latex adhesives are water-based adhesives, which generally have the disadvantages of poor antifreeze performance, unstable storage at low temperatures, easy freezing, and difficulty in normal use especially at low temperatures.

Abstract

The invention provides neoprene latex adhesive and a preparation method thereof. The adhesive comprises the following main components: neoprene latex, tackifier, zinc oxide water dispersing solution, promoting agent water dispersing solution, 2,6-di-tert-butyl paracresol, thickener, composite antifreezing agent, di(propylene glycol)butyl ether, defoaming agent and penetrating agent JFC. The invention has the advantage as follows: 1. the low temperature adhesive force is increased, xylene modified resin with cold resistant property can be used along with the neoprene latex adhesive so as to greatly increase the low temperature adhesive force and broaden the low temperature application field; 2. the antifreezing property is good, the low temperature storage of the neoprene latex adhesive isstable, composite antifreezing agent and di(propylene glycol)butyl ether are added so as to improve the antifreezing property and the low temperature storage stability; and 3. the water-based environmental protection system is adopted so as to reduce the pollution to the environment.

Description

technical field [0001] The invention relates to the field of water-based neoprene latex adhesives. More specifically, the present invention relates to a kind of neoprene latex adhesive that may be used in furniture industry and decoration industry and its preparation method. technical background [0002] At present, most of the commercially available adhesives used in the furniture industry and decoration industry are solvent-based adhesives, whose main components are rubber, mixed solvents, and tackifying resins. However, due to the need for environmental protection, as well as considerations for the hygiene and safety of production workers and consumers, the organic solvents contained in solvent-based adhesives are greatly restricted. Therefore, people began to pay more attention to non-solvent adhesives. Neoprene latex adhesive is one of them. It is characterized by low toxicity and environmental protection, non-flammable, no fire hazard, no explosion hazard, easy to use...
