A kind of methacrylate modified reactive resin

Abstract

A methacrylate-modified reactive resin relates to methacrylate resins used in the production of road markings or floor coatings. Aiming at the deficiencies of the existing known technologies, the methacrylic resin is improved, and the formula composition of the resin is adjusted to realize the purpose that the produced coating has environmental protection performance and can improve the corrosion resistance and adhesion of the coating. The basic formula is composed as follows according to the percentage of mass share: 0.1-15% crosslinking agent 35-60% methacrylate monomer or a mixture of methacrylate monomer and acrylate monomer 0-40% can Copolymerized with methacrylate or acrylate monomers with corrosion resistance Other types of monomer substances 10-50% prepolymer 0.5-2% reaction stabilizer N-tert-butyl-a-phenylnitrone. 1-20% methacrylate-modified oligomer, 0-5% accelerator and other additives, the sum of the mass shares of each component is 100%. The prepared floor coatings are superior to the "China Road Marking Paint Standard" indicators in terms of physical and chemical properties such as water corrosion resistance, alkali corrosion resistance, abrasion resistance, adhesion, and impact resistance.

Description

technical field [0001] The present invention relates to methacrylate resins for the production of road markings or floor coatings. Background technique [0002] At present, my country's road marking or floor coatings can be divided into two categories, one is traditional oil-based coatings, and the other is water-based coatings. During the film-forming process of oil-based paint, a large amount of organic gas will be released to pollute the environment, and its use is now restricted. Although water-based coatings greatly reduce the release of organic gases, their aging resistance and corrosion resistance are far inferior to oil-based coatings, which reduces the functional quality of coatings. The technical key to how to solve the problem of environmental protection and maintain or improve the functional quality of coatings is to solve the performance of resin, the basic raw material for the composition and production of coatings. [0003] In order to improve the performanc...

Problems solved by technology

Experiments have proved that the patent's selection of vinyl chloride and ethyl acetate copolymers instead of methacrylate copolymers will make the coatings less compatible and less dispersible to special pigments such as carbon black, which affects the composition of the coatings. film quality

Another example is another patent CN101501085B of Evonik, Germany, which does not add corrosion-resistant and solvent-resistant monomer substances, so the coating made of this resin has poor corrosion resistance; in addition, more than 30% The mass proportion of methyl methacrylate, the experiment proves that although the resin share of methyl methacrylate exceeds 30%, although it will increase the rigidity of the coating, it will obviously reduce the toughness and impact resistance of the coating after film formation. The adhesion performance of the invented resin to the substrate is not outstanding
