Embodiment 1

[0020] In a four-necked flask with a condenser, a dropping device, a stirring rod and a thermometer, add 210 grams of water, 2 grams of OP-10, 4 grams of dodecylsulfuric acid, 1 gram of ammonium persulfate, and 1 gram of sodium bicarbonate , slowly warming up to 75°C±5°C, using a separatory funnel, add dropwise 6 grams of acrylic acid, 15 grams of vinyltriethoxysilane, 60 grams of methyl methacrylate, 60 grams of butyl acrylate, N-hydroxyacrylamide 4 g, dropwise added in 2 hours, reacted at 80°C±5°C for 2 hours, cooled to below 30°C, filtered through 200 mesh to obtain a silicone-modified acrylic resin for paper with blue light.

[0021] Take the synthesized paper with blue light and apply 50 grams of diluted silicone-modified acrylic resin on the surface of ordinary filter paper, put it in an oven, and gradually increase the temperature of the oven from 60°C to 200°C.

Embodiment 2

[0023] Just change the amount of methyl methacrylate and butyl acrylate, of which 80 grams of methyl methacrylate and 40 grams of butyl acrylate, the ratio of methyl methacrylate and butyl acrylate is 2 to 1, other specific methods And process is identical with embodiment 1.

Embodiment 3

[0025] Just change the consumption of ammonium persulfate, ammonium persulfate is 0.6 gram, and other specific methods and technology are identical with embodiment 1.

Abstract

The invention relates to a paper used organosilicone modification acrylate emulsion and a preparation method thereof. An emulsion for heat-resisting paper and a preparation method of the emulsion are provided. The emulsion is pasted on a surface of common paper, heat-resistant performance of the paper is led to be improved under the condition that tensile strength and bursting strength of the paper are slightly improved. The emulsion is prepared by using raw materials, by weight, of 1-10% of unsaturated double bond organosilicone monomer, 1-5% of unsaturated acid, 10-35% of hard monomer, no less than 10% of soft monomer, 1-5% of emulgator, 0.1-1% of initiator, 0.1-1% of buffer agent, 1-8% of N-hydroxy acrylamide and 35-40% of solid content. And the raw materials are reacted in water to obtain the paper used organosilicone modification acrylate emulsion.

Description

technical field [0001] The invention relates to a silicone-modified acrylate emulsion for paper, which is especially suitable for the production of heat-resistant paper. Background technique [0002] Under high temperature conditions, due to the breakage of hydrogen bonds and the degradation of fibers, the heat resistance of paper will decrease. Both require paper to have good heat resistance, so heat-resistant paper came into being. However, the traditional method is mostly to change the ratio of fiber raw materials, and at the same time add heat-resistant additives during the papermaking process to improve the heat-resistant performance of paper. Or use mineral fiber and use a large amount of adhesive to produce special fiber paper, such as mica paper, stone paper, asbestos paper, etc. Although the heat resistance of this type of paper has been greatly improved, the production process is complicated and the energy consumption is high. The cost is high, and the overall ...
