Abstract

The invention discloses a preparation method of a green latex type rubber based adhesive. In order to overcome shortcomings of an existing adhesive, the green latex type rubber based adhesive is prepared from a rubber body, resins, chlorinated polyvinyl chloride, polyether polyol, sulphur, packing, a preservative, a dispersing agent, an accelerant, a plasticizer and a modifier by a certain method. The green latex type rubber based adhesive prepared by the method not only has good stability, but also is good in stretching strength and good in oxidative brittleness resistance when used, and further has quite high durability; all raw materials are environmentally friendly and non-toxic; an intermediate cannot harm human health and environments in a preparation process; and the latex type rubber based adhesive is used quite conveniently, defects on environmental protection of the traditional adhesive are overcome, and practical value is quite high.

Description

technical field [0001] The invention relates to a preparation of an adhesive, in particular to a preparation method of a green latex type rubber adhesive. Background technique [0002] Despite the tackiness of natural rubber, the bond strength is insufficient for many applications in adhesives derived from rubber alone, and most commercially available synthetic elastomers lack tack, either to themselves or to other surfaces, so there is no way to increase their Viscosity, to add resin tackifier or a large amount of latex and solvent system. [0003] Many organic compound raw materials used in the development process of traditional rubber adhesives, especially toxic and harmful solvents and thinners, are more harmful to environmental pollutants and human bodies. How to find an environmentally safe and stable, stretchable adhesive? Rubber adhesives with good strength and good resistance to oxidation and embrittlement have become a technical problem to be solved urgently in th...
