Problems solved by technology

All have the following disadvantages: ①Insufficient toughness, easy to crack under thermal stress or impact
②The system contains organic solvents, which are harmful to the human body
③Multiple processes must be adopted, the cycle is long, the efficiency is low, and the pinholes caused by solvent volatilization are easy to infiltrate the corrosive medium
However, there are mainly unreasonable raw material configurations, resulting in complicated material configurations, high requirements for production equipment, and complicated production processes, so it is difficult to be popularized and applied.

Embodiment Construction

[0021] Raw material name

[0022] Its processing and production process is to pour all the materials into the dispersion tank according to the proportion (remove the color paste part), use the disperser to disperse the materials evenly, add the color paste and continue to disperse until uniform, then it can be discharged and packaged. The products prepared in the above examples have the following characteristics: (1) The coating is continuous, dense, seamless, and has outstanding protective properties. ② The organic combination of anti-corrosion and heat preservation technology has greatly improved the quality and progress of the project. ③Brilliant color, can be adjusted at will. The material has high strength and outstanding aging resistance, and its service life is 5 times that of traditional materials. The measured technical parameters are: solid content 100%, gel time 15 seconds, tensile strength 22MPa, elongation at break 35%, tear strength 77KN / m, hardness,...

Abstract

This invention relates to an incubation and anticorrosion protective material of poly-urea elastomer. It is composed of A and B which weight ratio is equal. The component A is isocyanate, and B includes the weight components of following materials: 50-60% of amid-capped propylene oxide compound, 3-5% of diethyl toluenediamine, 4-6% of 2,4-diamido-3,5- methylthio chlorobenzene, 5-7% of N, N'-dialkyl diamine, 6-8% of N, N'- dialkyl methyl diamine, 2-4% of fumed silica, 3-5% of phosphate trimester, 3-7% of organosilicone, 4-6% of silica, 1-3% of zapon. It is suitable for the outside surface of large storage tank wall, overhead pipe or buried pipeline polyurethane foam, EPS foam, rock wool fiber, perlite or tank.

Description

technical field [0001] The invention relates to the field of polymer heat preservation and anticorrosion chemical materials, in particular to a polyurea elastomer heat preservation and anticorrosion protection material. Background technique [0002] Traditional anti-corrosion materials are generally epoxy, chlorinated rubber, and glass fiber reinforced plastics. All have the following disadvantages: ①Insufficient toughness, easy to crack under thermal stress or impact. ②The system contains organic solvents, which are harmful to the human body. ③Multiple processes must be adopted, the cycle is long, the efficiency is low, and the pinholes caused by solvent volatilization are easy to infiltrate the corrosive medium. Chinese Patent (Application No. 200510110358) "A Flame-Retardant Polyurea Anticorrosion Coating for Chemical Steel Structures and Its Manufacturing Process" discloses a new flame-retardant anticorrosion coating, which includes two components A and R , where the ...
