Embodiment 1

[0027] A kind of glue solution with high temperature resistance and flame retardancy and the preparation method of the automobile air filter paper using the glue solution, the automobile air filter paper comprises the following components according to the mass distribution ratio: acrylic resin 55%, flame retardant A 37.0%, flame retardant A Flame retardant B 3.0%, water resistant agent 5.0%; described flame retardant A is Hycar NH3069 halogen-free flame retardant acrylic emulsion, described flame retardant B is BASFMelapur 200 efficient halogen-free flame retardant, described water resistant agent It is BASF acrylate resin 950aL;

[0028] Its preparation method comprises steps as follows:

[0029] Step (1) Base paper preparation: Weigh mixed fibers composed of mercerized pulp, coniferous pulp fibers, broadleaf pulp fibers, and PET fibers and soak for 45 minutes to disintegrate. In the mixed fibers, 15.0% of mercerized pulp, needle Leaf pulp fiber accounts for 50%, broadleaf p...

Embodiment 2

[0033] With the dip coating glue solution described in embodiment 1, the difference is that raw material components and weight percentages thereof are composed as follows:

[0034] Acrylic resin 55%, flame retardant A 35.0%, flame retardant B 5.0%, water resistant agent 5.0%.

Embodiment 3

[0036] With the dip-coating glue solution described in Example 1, the difference is that the raw material components and their weight percentages are as follows: 55% of acrylic resin, 32.0% of flame retardant A, 8.0% of flame retardant B, and 5.0% of water resistant agent %.

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...
