Problems solved by technology

[0002] The main components of the existing transfer printing rubber are: isobutyraldehyde, polyvinyl butyral, and methanol. Because methanol is flammable and has a high volatile concentration, it produces toxic and irritating gas. Restrain the damage of artificial hematopoietic system, but isobutyraldehyde has a strong irritating smell, is poisonous and flammable, and has caused damage to the environment and human body, and the film-forming property of the modified rubber is poor, which is easy to cause waste and high production cost

Embodiment Construction

[0007] To produce 100kg of transfer rubber, 10kg of epoxy acrylate; 90kg of tap water; 2kg of 36% hydrochloric acid; 1kg of 10% sodium hydroxide; 3.4kg of 36% formaldehyde; 5kg of calcium chloride; 2kg of urea; 8.5kg of ethanol.

[0008] 1 Add 90kg of water to the reaction kettle, heat to 60°C, add 10kg of epoxy acrylate and stir evenly, then continue to heat up to 85°C, keep warm until the epoxy acrylate in the water is completely dissolved;

[0009] 2 Cool down to 75°C, then add 2kg of 36% hydrochloric acid, stir evenly, so that the pH value of the solution is between 1-2;

[0010] 3. After adding 3.4kg of 36% formaldehyde, stirring evenly, the viscosity increases continuously. After 60 minutes of reaction, when the glue solution slowly becomes cloudy and then white, accompanied by water precipitation, stop heating, and cool the glue solution through cold water. Cool to room temperature;

[0011] 4 Add 1kg of 10% sodium hydroxide to the glue for neutralization, so that the ...

Abstract

The invention discloses transfer size, comprising the following components in percentage by weight: 5-20% of epoxy acrylic ester or polyurethane acrylic ester, 80-97% of running water, 0.3-3% of 36% hydrochloric acid, 0.4-3% of 10% sodium hydroxide, 1.2-8% of 36% formaldehyde, 1-15% of calcium chloride, 1-3% of urea and 6-80% of ethyl alcohol. The transfer size disclosed by the invention has good film-forming property, is difficult to burn and is non-toxic and tasteless; raw material can be saved and requirements of environmental protection and human health are reached.

Description

technical field [0001] The invention relates to the technical field of printing rubber, and specifically designs a transfer printing rubber material. Background technique [0002] The main components of the existing transfer printing rubber are: isobutyraldehyde, polyvinyl butyral, and methanol. Because methanol is flammable and has a high volatile concentration, it produces toxic and irritating gas. To restrain damage to the artificial hematopoietic system, isobutyraldehyde has a strong pungent smell, is toxic and flammable, and has already caused damage to the environment and the human body, and the modified rubber has poor film-forming properties, which is easy to cause waste and high production costs. Contents of the invention [0003] The purpose of the present invention is to provide a transfer printing rubber material which has good film-forming properties, is not suitable for burning, has low cost, and conforms to environmental protection and human health against t...
