Abstract

The invention discloses a dipping adhesive for flexible industrial canvas and a preparation method of the dipping adhesive. The dipping adhesive comprises raw materials in parts by weight as follows: 20-30 parts of distilled water, 0.035-0.045 parts of sodium hydroxide, 55-65 parts of butadiene-vinyl pyridine latex, 20-30 parts of natural latex, 6-7 parts of ammonium water and 75-85 parts of a phenolic resin solution, wherein the phenolic resin solution comprises raw materials in parts by weight as follows: 150-170 parts of distilled water, 0.15-0.25 parts of sodium hydroxide, 10-11 parts of resorcinol and 12-14 parts of formaldehyde. Compared with the prior art, the dipping adhesive adopts phenolic resin prepared from resorcinol and the formaldehyde solution as well as butadiene-vinyl pyridine latex and natural latex as main raw materials, so that the canvas has better flexibility, the adhesion performance between a framework layer and a rubber layer is improved, the service life of a conveyor belt is prolonged, and the conveying accuracy of the conveyor belt is improved.

Description

technical field [0001] The invention belongs to the field of canvas treatment, and in particular relates to a dipping liquid for flexible industrial canvas and a preparation method thereof. Background technique [0002] The skeleton material of the conveyor belt is polyester dipped canvas. Polyester material has excellent comprehensive properties, such as high breaking strength, high elastic modulus, and moderate resilience. Therefore, polyester dipped canvas is used as the main skeleton material of conveyor belt products. , has replaced the traditional fiber fabrics and has been widely used in the field of conveyor belts at home and abroad. [0003] Polyester dipped canvas is an important part of the conveyor belt. At present, the two-bath method is usually used in the production of polyester canvas dipped. The first bath is pretreated (usually with epoxy or isocyanate compounds), and the second bath is It is a traditional resorcinol-formaldehyde-latex dipping solution. I...
