Abstract

The invention belongs to the technical field of adhesives, and discloses an anti-yellowing water-based adhesive as well as a preparation method and application thereof. The anti-yellowing water-based adhesive comprises the following components: a water-based polyurethane emulsion, a defoaming agent, a plasticizer, a cross-linking agent, a thickening agent and a surfactant. By adding the organic silicon defoaming agent and the surfactant, the problem of wettability of the existing sewing machine flanging adhesive is solved; by adding the cross-linking agent, the binding power and the strength of the adhesive are changed; and the viscosity is increased through the thickening agent.

Description

Technical field[0001]The present invention belongs to the technical field of adhesive, and more particularly to 黄 黄 黄 水性 胶黏 and the preparation method thereof and application thereof.Background technique[0002]The adhesive that is often used in the sucks of shoes and bags in the market is oily chloroprene and water-based chlorophenyl. Oil chloroprene contains high TVOC (total volatile organic compound), organic solvent emissions can cause waste of resources, environmental pollution and damage to direct contact people. Oil-resistant neoprene adhesive resistance, there is a stimulating solvent odor, with flammable risk.[0003]With the price of raw materials such as neoprene, organic solvents, the cost of oil-resistant causing glue is getting higher and higher. When the oily needle is plastic, stirring is required for 2 to 4 hours, heating heating, 60 ~ 90 ° C for 4 to 6 hours, the total length of production is 8 ~ 12 hours, long production time, large energy consumption, low production ...
