Problems solved by technology

However, the process of applying the adhesive during use also brings a lot of inconvenience and quality problems to the entire rubber lining operation.
For example: 1. Adhesives are mostly flammable and explosive substances. There are safety hazards in transportation, storage and painting. They are flammable, explosive, toxic and harmful; Human health and the environment will cause certain damage; 3. The adhesive performance and corrosion resistance of the adhesive will be affected by the formulation technology and painting process, resulting in unstable performance, poor adhesive performance, and even rubber linings that cannot stick

Embodiment 1

[0021] Example 1: A self-adhesive rubber anti-corrosion lining (parts by weight): 100 parts of corrosion-resistant rubber, 200-280 parts of tackifier, 280-380 parts of softener, 50-80 parts of reinforcing aid, 0.5 parts of vulcanizing agent -1.0 parts, 1.5-2.5 parts of anti-aging agent A, 1.5 parts of anti-aging agent B, 0.5-2.0 parts of accelerator, the error range of the above ingredients is controlled within 5%.

[0022] The corrosion-resistant rubber refers to butyl rubber.

[0023] The tackifier refers to phenolic resin.

[0024] The softener refers to polyisobutylene.

[0025] The reinforcing agent is carbon black.

[0026] The vulcanizing agent refers to sulfur.

[0027] The anti-aging agent A refers to ketamine.

[0028] The anti-aging agent B refers to polyphenols; the accelerator refers to a thiuram accelerator.

Embodiment 2

[0029] Example 2: A method of making a self-adhesive rubber anti-corrosion lining, 1) 100 parts of corrosion-resistant rubber, 200-280 parts of tackifier, 50-80 parts of reinforcing aid, 0.5-1.0 parts of vulcanizing agent, anti-aging Add 1.5-2.5 parts of agent A, 1.5 parts of anti-aging agent B, and 0.5-2.0 parts of accelerator according to a certain order of addition (rubber→tackifier+reinforcing agent→anti-aging agent+vulcanizing agent+tackifier→accelerator) Mix evenly in the rubber internal mixer, unload and park, then add 280-380 parts of softener to the rubber intermeshing mixing equipment, stir and mix evenly to make semi-finished products for use; 2) Semi-finished products pass through the extruder Applied on one side of the qualified rubber lining film and rolled up, it becomes a single-sided self-adhesive rubber anti-corrosion lining film. The tackifier is added twice and the total amount added does not exceed 280 parts.

[0030]

Embodiment 3

[0031] Example 3: A new construction process for self-adhesive rubber anti-corrosion lining

[0032] 1) For the acceptance of sand blasting and derusting equipment, the surface of the equipment to be lined with rubber should meet the technical requirements for rubber lining;

[0033] 2) Lofting: cutting and lofting according to the surface shape of the rubber-lined equipment and the rubber-lined process, the lofting requires accurate, reasonable, and even arrangement of materials, and minimizes seams;

[0034] 3) Lining: Align the placed film with the lining part of the equipment, then slowly pull out the release paper on the film, and press the film while pulling the release paper, so as to complete the lining of the entire film;

[0035] The seam direction of the film lining should be determined according to the equipment structure: the seam direction of the equipment connection pipe or the inner wall should follow the flow direction of the medium; the seam direction of the ...

Abstract

The invention relates to a new construction process of a self-adhesive rubber anticorrosive lining, wherein the self-adhesive rubber anticorrosive lining can be directly applied on the surface of a protected iron and steel metal without the brushing of an adhesive during rubber lining pasting operation, and the components comprise: 100 parts of a corrosion-resistant rubber, 200-280 parts of a tackifier, 280-380 parts of a softener, 50-80 parts of a reinforcing aid, 0.5-1.0 part of a vulcanizing agent, 1.5-2.5 parts of an anti-aging agent A, 1.5 parts of an anti-aging agent B and 0.5-2.0 partsof an accelerant. According to the invention, the adhesive is not required to be brushed, so that the potential safety hazards of transportation, storage and brushing in the manufacturing process of the rubber anticorrosive lining are solved, and the inflammable, explosive, toxic and harmful conditions are avoided; the flammable and harmful gas volatilization is avoided, and it is guaranteed thathuman health and the environment cannot be polluted; and the bonding strength of the rubber sheet of the anti-corrosion rubber lining equipment manufactured by adopting the process and the iron and steel metal reaches the bonding performance of the original adhesive, and the anti-corrosion performance meets the actual application requirements.

Description

technical field [0001] The invention relates to a new construction technology of the self-adhesive rubber anti-corrosion lining, which can directly apply the self-adhesive rubber anti-corrosion lining to the protected steel and metal surface without applying adhesive during the rubber lining lining operation. Background technique [0002] Rubber anti-corrosion lining has excellent chemical corrosion resistance, high temperature resistance, wear resistance, flexibility and high elasticity. Therefore, it is widely used in petrochemical, nonferrous metallurgy, power desulfurization, steel refining, industrial flue gas emission, food, medicine and corrosion protection of environmental protection facilities. Such as various acid and alkali storage tanks, reactors, and floor isolation layers in the chemical and petrochemical industries; ships, trains, and automobile tanks for transporting acid and alkali; electrolytic cells in the hydrometallurgical industry and the chlor-alkali i...
