Embodiment 1

[0046] 10g of silane coupling agent KH570 was dissolved in deionized water with a pH value of 5 adjusted with glacial acetic acid, and stirred for 30 minutes to fully hydrolyze it; then, under stirring conditions, 110g of nano-SiO 2 Add it to the above solution, stir it well for 1 hour, and then ultrasonically disperse it for 30 minutes; filter the above mixture and wash it with deionized water and absolute ethanol; dry the obtained precipitate at 70°C for 12 hours; 2 Crush and grind to a particle size of less than 500nm to obtain modified nano-SiO 2 . The modified nano-SiO prepared above 2 Dispersed into the plasticizer for acetate fiber molding, formulated to contain 2.5wt% modified nano-SiO 2 Plasticizer, used for forming and processing of acetate tow, modified nano-SiO 2 The amount is 2wt‰ of the weight of the formed acetate tow.

Embodiment 2

[0048] Adopt silane coupling agent vinyltriethoxysilane (A151), all the other are the same as embodiment 1.

Embodiment 3

[0050] According to the preparation method described in Example 1 and Example 2 respectively, prepare silane coupling agent KH570 and silane coupling agent vinyltriethoxysilane (A151) modified nano-SiO 2 , modified nano-SiO with KH570 and A151 at a weight ratio of 1:1 2 Repeat the mixing to make it uniform, and then the composite modified nano-SiO prepared above 2 Dispersed into the plasticizer for acetate fiber molding for molding and processing of acetate fiber tow, modified nano-SiO 2 The amount is 2wt‰ of the weight of the formed acetate tow.

Abstract

The invention relates to a cigarette filter up additive and the preparation and application method thereof. The invention relates to a preparation and application of the silane coupling agent finished and modified nanometer of SiO2 and belongs to the cigarette filter up preparation technique field, wherein the additive is the nanometer SiO2 finished and modified by the silane coupling agent and the content of the silane coupling agent is 4-15 % of the nanometer SiO2; during the shaping of the filter up, a plasticizer containing the modified nanometer SiO2 is directly used to prepare the modified filter up. The invention has the advantages that: the silane coupling agent finished and modified nanometer SiO2 can effectively lower the poisonous substances; the coke tar, phenol, and hydroxybenzene substances in the cigarette smoke are separately lowered by 27.4 %, 59.1 % and 38.2 %; the invention has simple process, low cost and good utility.

Description

technical field [0001] The invention belongs to the technical field of cigarette filter preparation, and relates to a cigarette filter additive, its preparation and its application in forming cellulose acetate tow. Background technique [0002] The harmful substances produced by cigarette combustion mainly include tar, carbon monoxide, hydrocyanic acid, volatile aldehydes, ammonia, nitrosamines, benzo[α]pyrene and phenols. There are cancer-inducing substances in tar, which can change the genetic structure of cells, turning normal cells into cancer cells, or stimulating stimulated cells, leading to the formation of tumors. Phenolic compounds are a kind of cell protoplasm poison. Its toxic effect is to chemically react with the protein in the cell protoplasm to form denatured protein and make the cell inactive. The pathological changes it causes mainly depend on the concentration of the poison. It can denature cells and coagulate proteins at high concentrations. Although the ...
