Water-based graphene metal rustproof primer with good anti-cracking and insulating properties and production method of water-based graphene metal rustproof primer

Abstract

The invention discloses water-based graphene metal rustproof primer with good anti-cracking and insulating properties. The water-based graphene metal rustproof primer is prepared from the following raw materials in parts by weight: 44 to 45 parts of acrylate emulsion, 6.6 to 6.9 parts of waste polystyrene foam, 4.5 to 4.7 parts of graphene, 8 to 9 parts of glass fiber, 6 to 8 parts of tributyl citrate, 11 to 12 parts of potassium feldspar, 2 to 4 parts of xanthan gum, 2 to 3 parts of dimethyl silicone oil, 0.1 to 0.2 part of ylang-ylang essential oil, 1.7 to 1.9 parts of perfluorooctyltriethoxysilane, 19 to 22 parts of a pigment and a proper amount of de-ionized water. According to the water-based graphene metal rustproof primer, the waste polystyrene foam-modified acrylate emulsion is used as a film forming substance, and performance including the hardness, chemical resistance, water resistance, pulverization resistance and the like of a coating film is improved, and a proper amount of grapheme is creatively added to modify the coating film, so that the anticorrosion and rustproof properties of a coating are improved; the rustproof primer prepared by matching auxiliary materials including modified potassium feldspar and the like has good anti-cracking and insulating properties, is environmentally friendly and has no pollution, and has remarkable utilization effect.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based graphene metal antirust primer with good crack resistance and insulation performance and a preparation method thereof. Background technique [0002] With the development of the paint industry and painting towards low pollution, water-based paints are increasingly emerging. The loss caused by metal corrosion is very serious, and the anti-corrosion coating of metal materials has attracted attention at home and abroad. Solvent-based antirust coatings have several problems such as air pollution, toxicity and fire hazard. Therefore, the development of water-based antirust primer has been paid attention to. Water-based anti-rust paint is formulated with water as the dispersion medium, using multiple anti-rust mechanisms such as physics and chemistry, and formulated according to chemical principles such as chemical transformation, network and reaction. It is...
