Problems solved by technology

However, it is not an easy task to replace gasoline with water. There are many polymer emulsions with water as the carrier, such as various synthetic latexes: styrene-butadiene latex, neoprene latex, cyanide-butadiene latex, VAE latex, etc. Common natural rubber latex, but generally have poor adhesion, low initial adhesion and holding strength, which cannot meet the requirements of use

Abstract

The invention discloses an ultra-micro-emulsion high-viscosity resin, its preparation method and application. The ultra-micro-emulsion high-viscosity resin comprises tackifying resin, rosin acid, water, alkali, and polyol. According to the invention, by adding rosin acid in tackifying resin to react rosin acid with alkali to produce a primary soap, emulsification is generated, and because of good tackifying capacity of rosin acid, the stability of the emulsion is increased, and the tackness is not affected; then an ultrasonic emulsifier is used for preparing an emulsion having small particles, tiny dispersity and good stability; and finally polyol is added based on ultrasonic processing to obtain a interface tension force range suitable for emulsification, and a transparent gel emulsion can be prepared in the range, thus the ultra-micro-emulsion high-viscosity resin having good tackifying effect can be obtained. A water-emulsion adhesive for shoes prepared by using ultra-micro-emulsion high-viscosity resin, latex and the like has a primary adhesion of larger than 1000 Pa / N, and a permanent adhesion of larger than 2000 Pa / N.

Description

technical field [0001] The invention relates to an adhesive, a processing technique and an application thereof, in particular to an ultramicroemulsion high-viscosity resin, a preparation method and an application thereof. Background technique [0002] At present, China produces more than 380 million pairs of rubber shoes annually, with an output value of more than 10 billion yuan. In the production process, various adhesives are used in large quantities. Among them, the traditional gasoline glue adhesive is used in the bandage adhesive and disulfide outsole adhesive, and each pair of rubber shoes uses 50 grams of gasoline glue (actually far from far more than this number) to calculate, need to use more than 2000 tons of gasoline mortar, in the composition of gasoline mortar, the gasoline content exceeds 80%, so converted, it will consume more than 1600 tons of gasoline, and this 1600 tons of gasoline is calculated according to Converted at the current price, it is worth at ...
