Problems solved by technology

The above patents have great defects in the selection of materials. Due to the conductivity of the fibers, the permeability resistance of the materials is reduced, and the materials are prone to bulging and leakage during use. At the same time, the materials have certain toxicity, which limits the use material development

Embodiment 1

[0033] Prepare polyester polyurethane modified epoxy resin, preparation method is as follows:

[0034] (1) Synthesis of hydroxyl-terminated resin

[0035] Add 12.85kg of trimethylolpropane, 5kg of glycerin, 24.35kg of phthalic anhydride, 4kg of maleic anhydride, and 3kg of xylene into the reaction kettle, start stirring and heat up, when the temperature rises to 120°C, slowly heat up , when the temperature rises to 200°C, keep it warm for 4-6 hours, and measure its acid value and hydroxyl value every 20 minutes. When the acid value is ≤1.0mgKOH / g and the hydroxyl value reaches the specified value of 56±5mgKOH / g, stop heating and start Vacuum to remove the solvent in the resin, cool down and filter to obtain the hydroxyl-terminated resin, which is packaged for later use;

[0036] (2) Synthetic prepolymer

[0037] Add 20kg of TDI into the reactor, start stirring and raise the temperature. When the temperature rises to 40-50°C, add 25kg of hydroxyl-terminated resin and 5kg of N...

Embodiment 2

[0042] The polyester urethane modified epoxy resin is added by the weight listed in table 1, i.e. 15kg, and fillers, auxiliary materials, and auxiliary agents other than glass flakes by the weight listed in table 1 and stirred for 15 minutes, and then The mixing material is ground to 20-30μm by a three-roller mill to obtain the grinding material, and then the grinding material, 15kg polyester polyurethane modified epoxy resin and the weight listed in the glass flakes in Table 1 are added to the high-speed mixer, stirred for 30 minutes and mixed Evenly, get the required A component of the new polymer anti-corrosion coating material, put the A component into the iron bucket for standby, when construction is used, first clean and derust the surface of the equipment that needs to be coated with the anti-corrosion coating material, Then take diaminodiphenylmethane according to the weight listed in the curing agent in Table 1 as component B and component A and stir and mix evenly to ...

Embodiment 3

[0044] The method of Example 1 was repeated at the weights of the various components specified in Table 1, and the test results are listed in Table 1.

Abstract

The invention relates to a novel polymer anticorrosion painting material. The painting material is characterized by consisting of a component A and a component B, wherein the component B is a curing agent and accounts for 10-30 percent relative to the weight parts of the component A; and the component A comprises the following components in parts by weight: 30-50 parts of polyester polyurethane modified epoxide resin which serves as a main material and has the solid content of 100 percent, 30-50 parts of glass flakes with different flake diameters, 3-5 parts of nanoscale titanium dioxide and 10-20 parts of at least one of titanium pigment, mica powder and carbon black in any ratio, 1-5 parts of at least one of asbestos powder, lithopone and talc powder serving as auxiliary materials in any ratio, and 0.3-1 part of at least three of defoaming agent, flatting agent, thixotropic agent and coupling agent serving as aids in any ratio. The coating material has the advantages of convenience and rapidness of construction, high bonding strength, low using cost, high corrosion resistance, high wear resistance, favorable penetration resistance, higher temperature resistance and solid content of 100 percent.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a coating material. Background technique [0002] In nonferrous metals, metallurgy, petrochemical, electric power and other industries, a large number of equipment spare parts operate in the environment of acid, alkali and salt medium. Due to the harsh environment, the service life of equipment and spare parts is greatly reduced, which directly leads to corrosion damage of equipment, and the damage of equipment Reduced operating efficiency, abnormal downtime, etc. lead to a substantial increase in production costs, and the generation of waste equipment and spare parts also leads to a waste of resources. [0003] To solve the above problems, the methods currently used mainly include: lining the interior of the equipment with ceramic tiles, rubber glass fiber reinforced plastics, anti-corrosion coatings, etc., or using anti-corrosion and wear-resistant materials such as stainless...
