Problems solved by technology

Early asphalt used as anti-corrosion coatings was mainly based on coal tar pitch epoxy resin coatings. However, due to poor adhesion, poor impermeability, complex construction technology, and relatively high quality requirements for construction personnel, this coating has not been widely promoted. In the later period, people began to study petroleum asphalt anti-corrosion coatings, but due to the long curing time and uneven coating film, they were only used as base coatings.

Embodiment Construction

[0013] (1) Prepare resin solubilizer: put the measured toughening agent and diluent into the reaction kettle in turn, shear at high speed for 8 minutes, stir well, and let it stand for later use.

[0014] (2) After measuring the epoxy resin, slowly add the resin solubilizer prepared in step (1), shear at a high speed evenly, and set aside.

[0015] (3) Raise the temperature of the base asphalt to 140-145°C, slowly add the product of step (2), stir evenly, keep the temperature constant for 1 hour, then add the curing agent and filler, mechanically stir evenly, keep the temperature at 140-145°C, keep the constant temperature for 2 hours , that is, the finished corrosion-resistant coating is obtained.

[0016] Reagents with different components were tested, and the prepared corrosion-resistant coatings all met the requirements, as shown in Table 1.

Abstract

The invention relates to a corrosion-resistant coating and a processing method thereof and belongs to the technical field of reprocessed raw materials. The corrosion-resistant coating is prepared from components in percentage by weight as follows: 40%-60% of asphalt, 22%-43% of resin, 15%-25% of a curing agent and 2%-3% of filler. The processing method is applicable to processing of the corrosion-resistant coating, and the corrosion-resistant coating has the advantages of high corrosion-resistant effect and the like.

Description

technical field [0001] The invention relates to a corrosion-resistant coating and a processing method thereof, belonging to the technical field of recycled raw materials. Background technique [0002] Asphalt is a mixture of various polymers with complex chemical composition. It has unique rheology, good adhesion, anti-aging and waterproof and anti-corrosion capabilities. Early asphalt used as anti-corrosion coatings was mainly based on coal tar pitch epoxy resin coatings. However, due to poor adhesion, poor impermeability, complex construction technology, and relatively high quality requirements for construction personnel, this coating has not been widely promoted. In the later stage, people began to study petroleum asphalt anti-corrosion coatings, but due to the long curing time and uneven coating film, they were only used as base coatings. Based on this, this application is made. Contents of the invention [0003] Aiming at the above-mentioned defects existing in conv...
