Problems solved by technology

However, the disadvantages of water-based adhesives mainly include slow drying speed, poor water resistance, poor freeze resistance, and high temperature resistance, and often need to be modified. For example, the Chinese patent application "a water-based polyurethane adhesive" with the publication number CN 102965060 B uses 2 , 6-toluene diisocyanate, 1,4-butylene adipate, diethylene glycol, and dimethylol butyric acid are used as raw materials to prepare prepolymers, and trimethylolpropane and epoxy resin are added Carry out cross-linking, add triethylamine for neutralization reaction to generate salt, add butyl acrylate and water for emulsification, add an appropriate amount of potassium persulfate to polymerize butyl acrylate, and obtain a modified water-based polyurethane adhesive. After the mixture is formed into a film, it has good thermal stability, chemical resistance and mechanical properties

Abstract

The invention relates to a waterborne adhesive for an automobile filter and a preparation method of the waterborne adhesive. The adhesive comprises the following components in parts by weight: 40-80 parts of hydrophilic polymer emulsion, 10-20 parts of enhancer, 1-3 parts of stabilizer, 1-4 parts of thixotropic agent, 1-2 parts of silyl ether, 20-30 parts of glycerin, 0.05-1 part of zinc oxide and1-3 parts of sodium dodecyl sulfate. The adhesive is curable at normal temperature, high in drying speed, good in water resistance, high in bonding strength, stable in property, few in influences from temperature and humidity, free of releasing solvents, green, environment-friendly, nontoxic and safe in use.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-based adhesive for automobile filters and a preparation method thereof. Background technique [0002] The filter is one of the key components to ensure the durability and reliability of the engine. The engine has three filters of air, oil and fuel, generally called "three filters", plus the air conditioning filter, commonly known as "four filters", which are respectively responsible for the lubrication system, the medium of the combustion system, the engine intake system, and the cabin. Filtration of the air circulation system. The air filter is mainly used in pneumatic machinery, internal combustion machinery and other fields. Its function is to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing the probability of abrasion and damage. Automobile engines are...
