High-temperature-resistant flame-retardant glue solution and preparation method of automobile air filter paper using glue solution

Abstract

The invention discloses a high-temperature-resistant flame-retardant glue solution and a preparation method of automobile air filter paper applying the glue solution and relates to the field, and the automobile air filter paper comprises the following components in percentage by mass: 54-65% of acrylic resin, 30-35% of a flame retardant A, 3.0-8.0% of a flame retardant B and 2.0-6.0% of a water repellent agent. The flame retardant A is a self-crosslinking halogen-free acrylic emulsion, the decomposition temperature is greater than or equal to 270 DEG C, and the filter paper treated by the flame retardant has lower pressure drop and air permeability; when the flame retardant A and the flame retardant B are matched for use, various action mechanisms act together, so that the use amount of the flame retardants is reduced, and the filter paper can have a more excellent flame-retardant effect and a higher-temperature-resistant effect; and the water repellent agent is BASF acrylate resin 950aL, is formaldehyde-free environment-friendly high-strength water-based resin compared with melamine resin commonly used in the market, has excellent thermal stability and mechanical properties, and obviously improves the processability of paper.

Description

technical field [0001] The invention relates to the technical field of filter paper, in particular to a glue with high temperature resistance and flame retardancy and a method for preparing automobile air filter paper using the glue. Background technique [0002] As we all know, the engine is called the "heart" of the car, and the air filter acts as the "lung" of the car, which can effectively filter the impurities in the inhaled air, thereby reducing the probability of car "heart attack" and prolonging the use of the engine life. [0003] Air filter paper for vehicles is one of the main materials for preparing air filters. The most commonly used one is resin-treated microporous filter paper, which has the advantages of light weight, low cost, stable performance, and good filtering effect. The main component of porous filter paper is cellulose, and high temperature pyrolysis will cause the filter paper to burn, often causing the car engine to catch fire, and even the tragedy...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the flame retardant series existing on the market all reduce the air permeability of the filter paper to varying degrees, and the strength drops seriously at high temperatures, does not have high temperature resistance, and the filter paper is brittle after carbonization at high temperatures. Flame-retardant filter paper is easy to absorb moisture and deform, which affects the filtration performance. Provide a high-temperature-resistant flame-retardant glue and a method for preparing automotive air filter paper using the glue
