Problems solved by technology

[0002] Most of the existing shoe glues are solvent-based, which is volatile and contains harmful ingredients. During the production process, the harmful ingredients are easy to volatilize into the workshop, which will affect the health of production workers. Volatilization will affect the health of users; some shoe glues are made of hot melt glue, which is relatively hard, which makes the soles poor in air permeability, especially after encountering water during use, it will cause degumming and shorten the service life of the shoes. short

Abstract

The invention relates to the hot melt adhesive field, and especially discloses a soft, air-permeable shoe rubber without pollution and a production method therefor. The shoe rubber is composed of, by weight, 0-5 parts of polyethylene wax, 10-20 parts of naphthenic oil, 5-15 parts of metallocene catalysis polyolefin, 10-25 parts of amorphous-form poly-alpha-olefin, 5-15 parts of hydrogenated ethylene-isoprene-styrene copolymers, 5-10 parts of phenolic aldehyde-terpene resins, 10-20 parts of hydrogenated C5 petroleum resins, 5-10 parts of polyisobutylene, 0.8-1.5 parts of antioxidants and 0.5-1.5 parts of coupling agents. The produced shoe rubber is soft and good air permeability. In seal air permeability tests, sealing is carried out with the shoe rubber under 1.5 barometric pressure, inside and outside air pressure balance is achieved after 1h, the breaking elongation rate of the shoe rubber is more than 300%, the tensile strength is more than or equal to 3 MPa, the viscosity is 3000+ / -1000MPa.S (180 DEG C, a rotary viscosimeter), the C peel strength is more than 40N / 2.5cm ( peeling at the temperature of 180 DEG C), and the softening point is more than 135+ / -5 DEG C.

Description

technical field [0001] The invention relates to the field of hot melt adhesives, in particular to shoe adhesives and a manufacturing method thereof. Background technique [0002] Most of the existing shoe glues are solvent-based, which is volatile and contains harmful ingredients. During the production process, the harmful ingredients are easy to volatilize into the workshop, which will affect the health of production workers. Volatilization will affect the health of users; some shoe glue uses hot melt glue, which is relatively hard, which makes the soles poor in air permeability, especially when it encounters water during use, it will cause degumming and shorten the service life of the shoes. short. Contents of the invention [0003] The object of the present invention is to provide a kind of soft, breathable, non-polluting shoe glue and its production method in order to solve the deficiency of above-mentioned technology. [0004] In order to achieve the above object, t...
