Abstract

The invention discloses a heat-resistant saline-water-erosion-resistant chloroprene spray adhesive and a preparation method and application thereof. The heat-resistant saline-water-erosion-resistant chloroprene spray adhesive is prepared from the following raw materials in parts by weight: 120-140 parts of chloroprene rubber, 10-25 parts of chlorinated rubber, 90-120 parts of phenolic resin and the like. The chloroprene spray adhesive resistant to heat and saline water erosion can meet the requirements of spray adhesives for ocean containers for temperature and saline water resistance, the high temperature resistance can reach 70-100 DEG C, and the requirement for continuous high-temperature sailing of the ocean containers in a high-temperature sea area is met; and a uniform film can be formed on the metal plate through glue spraying, salt in seawater is prevented from making contact with the metal plate, the metal plate is prevented from being corroded and rusted, the obtained glue film is not degummed within 20 days after being soaked in saline water with the mass concentration being 5%, the saline water cannot permeate the glue film to corrode the alloy aluminum plate, and the salt water resistance is excellent.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a heat-resistant and salt-water corrosion-resistant chloroprene spray adhesive and its preparation method and application. Background technique [0002] Spray-type neoprene adhesives are low-viscosity adhesives. Because of their high bonding strength and durability, they can be used in a wide range of applications. At present, the spray-type neoprene mainly includes sulfur-adjusted neoprene spray glue and neoprene spray glue adjusted by regulator D; among them, sulfur-adjusted neoprene spray glue is made of sulfur-adjusted neoprene rubber, zinc oxide and light magnesium oxide. Mix on the rubber mixer, then dissolve in the solvent, and then mix the phenolic resin with the glue, and the chloroprene rubber spray glue adjusted by the regulator D generally dissolves the chloroprene rubber directly in an oxygen-containing organic solvent. Then add the solution of phenolic resin and ...
