Abstract

The invention discloses impregnation emulsion for air filtration paper and a preparing method thereof. The purpose is to overcome the defects of low filtration efficiency, small dust capacity and poor water resistance of existing impregnation emulsion. The impregnation emulsion is prepared from, by mass, polymerization components including 10-30% of octamethylcyclotetrasiloxane, 1-5% of sodium dodecyl benzene sulfonate, 3-10% of dodecylbenzene sulfonic acid, 1-5% of OP-10 and 50-80 parts of deionized water. The preparing process of the impregnation emulsion for the air filtration paper includes the steps that octamethylcyclotetrasiloxane, sodium dodecyl benzene sulfonate, OP-10 and the deionized water are mixed uniformly and homogenized to obtain A, sodium dodecyl benzene sulfonate is added into A, the mixture is heated to the reaction temperature of 70-90 DEG C, reacts for 5-10 h and is discharged.

Description

technical field [0001] The invention relates to an impregnation emulsion for air filter paper, in particular to an impregnation emulsion for air filter paper in the automobile industry. Background technique [0002] The air filter paper in the automotive industry has been treated with oil for a long time. Oil can provide filter paper with many good properties, such as better filtration efficiency, better water resistance, better interception of re-diffused solid particles, etc. As early as the early nineties, oil-treated filter paper has been used in air filtration systems due to its excellent filtration efficiency and service life. Although the oil is used to treat the filter paper, although the effect is obvious, there are many problems in the production and use of the oil, such as difficulty in large-scale production, flammable and explosive, and poor stability of the finished product. Contents of the invention [0003] The present invention overcomes the above existin...
