Embodiment 1

[0032] A preparation process of pressure-sensitive adhesive for high-viscosity masking tape:

[0033] Step 1: According to each group of formulas, it is made of the following raw materials in parts by weight: 60 parts of main rubber, 2 parts of antioxidant, 3 parts of rosin resin, 4 parts of emulsifier, 9 parts of acrylic acid, 3 parts of sodium polyacrylate, propylene butyl 30 parts of acid ester, 2.5 parts of degassing agent, 4 parts of chitosan, 15 parts of acrylamide, 8 parts of propylene glycol methyl ether, 10 parts of dimethyl succinate, 7 parts of crosslinking agent, first take 60 parts of main rubber and propylene Add 15 parts of amide into the reaction kettle for mixing and kneading. The reaction kettle is closed and filled with nitrogen protection, so that the temperature in the reaction kettle rises slowly to 50°C, with an average of 1°C / h, so that the main rubber and acrylamide Perform a mixing reaction, then add 3 parts of sodium polyacrylate and 30 parts of prop...

Embodiment 2

[0043] A preparation process of pressure-sensitive adhesive for high-viscosity masking tape:

[0044] Step 1: According to each formula, it is made of the following raw materials in parts by weight: 80 parts of main rubber, 4 parts of antioxidant, 5 parts of rosin resin, 6 parts of emulsifier, 9 parts of acrylic acid, 3 parts of sodium polyacrylate, propylene butyl 25 parts of acid ester, 1.5 parts of degassing agent, 4 parts of chitosan, 12 parts of acrylamide, 8 parts of propylene glycol methyl ether, 8 parts of dimethyl succinate, 5 parts of crosslinking agent, first take 80 parts of main rubber and propylene Add 12 parts of amide into the reactor for mixing and kneading. The reactor is closed and filled with nitrogen protection, so that the temperature in the reactor rises slowly to 55°C, with an average of 1°C / h, so that the main rubber and acrylamide Perform a mixing reaction, then add 3 parts of sodium polyacrylate and 25 parts of propylene butyrate into the reaction ke...

Embodiment 3

[0054] A preparation process of pressure-sensitive adhesive for high-viscosity masking tape:

[0055] Step 1: According to each formula, it is made from the following raw materials in parts by weight: 70 parts of main rubber, 3 parts of antioxidant, 4 parts of rosin resin, 5 parts of emulsifier, 8 parts of acrylic acid, 2 parts of sodium polyacrylate, propylene butyl 28 parts of acid ester, 1.5 parts of degassing agent, 3.5 parts of chitosan, 13 parts of acrylamide, 7 parts of propylene glycol methyl ether, 9 parts of dimethyl succinate, 6 parts of crosslinking agent, first take 70 parts of main rubber and propylene Add 13 parts of amide into the reaction kettle for mixing and kneading. The reaction kettle is closed and filled with nitrogen protection, so that the temperature in the reaction kettle rises slowly to 53°C, with an average of 1°C / h, so that the main rubber and acrylamide Carry out mixing reaction, then add 2 parts of sodium polyacrylate and 28 parts of propylene b...

Abstract

The invention relates to a tape and a preparation process thereof, in particular to a high-viscosity masking paper tape and a preparation process thereof. The invention provides the high-viscosity masking paper tape with the advantages of no toxicity, no harm, high viscosity and good use performance, and the preparation process thereof. A high-viscosity masking paper tape glue formula comprises the following raw materials in parts by weight: 60 to 80 parts of main body rubber, 2 to 4 parts of antioxidants, 3 to 5 parts of rosin ester, 4 to 6 parts of emulsifiers, 7 to 9 parts of acrylic acid, 1 to 3 parts of sodium polyacrylate, 25 to 30 parts of propylene butyrate and 1.5 to 2.5 parts of degassing agents; the preparation process comprises five steps. The prepared high-viscosity masking paper tape has high viscosity and can be used in life and industry; the condition that the falling phenomenon occurs within a short time is avoided; ageing resistance, water resistance and solvent resistance are realized; the isolation performance of base paper is improved.

Description

technical field [0001] The invention relates to an adhesive tape and a preparation process thereof, in particular to a high-viscosity masking tape and a preparation process thereof. Background technique [0002] With the development of the economy and the advancement of science and technology, China has become a processing factory and a big consumer in the world's adhesive industry.
