Embodiment Construction

[0016] A water-based graphene metal antirust primer that can resist electromagnetic radiation is made of the following raw materials in parts by weight: acrylate emulsion 37, waste polystyrene foam 7.7, graphene 4.4, tea alkaloid 2.2, triglycerol mono Stearate 8, polyester fiber 5, nano barium ferrite magnetic powder 2, dandelion powder 9, bagasse 15, vinyl triethoxysilane 0.8, pigment 17, deionized water in proper amount.

[0017] A kind of preparation method of described anti-electromagnetic radiation waterborne graphene metal antirust primer may further comprise the steps:

[0018] (1) Dry and grind dandelion powder and bagasse through a 120-140 mesh sieve, add triglycerol monostearate and stir in a high-speed mixer for 10-15 minutes, then heat treatment at 550-610°C for 20 -30 minutes, cooled to room temperature and added nano-scale barium ferrite magnetic powder for ultrasonic grinding for 40-50 minutes to obtain modified mixed powder;

[0019] (2) Stir and mix the tea a...

Abstract

The invention discloses anti-electromagnetic-radiation water-based graphene metal rust-inhibitive primer. The primer is prepared from the following raw materials of, by weight, 37-40 parts of acrylate emulsion, 7.7-8.5 parts of waste polystyrene foam, 4.4-5.6 parts of graphene, 2.2-2.5 parts of tea alkaloid, 8-10 parts of tripolyglycerol monostearates, 5-7 parts of polyester fibers, 2-4 parts of nano-barium ferrite magnetic powder, 9-11 parts of dandelion powder, 15-18 parts of bagasse, 0.8-1.4 part of vinyl triethoxysilane, 17-20 parts of pigments, and appropriate amount of deionized water. According to the anti-electromagnetic-radiation water-based graphene metal rust-inhibitive primer, the acrylate emulsion is modified into film forming matter by using the waste polystyrene foam, so that the hardness, the water resistance, the chalking resistance and other performance of a coated film are improved; in addition, the appropriate amount of graphene is added innovatively and is modified, so that the corrosion resistance and rust resistance of a coating are improved; and meanwhile, the rust-inhibitive primer prepared by adding modified mixed powder and other auxiliaries can be used as LED bulb primer and has the advantage of being resistant to electromagnetic radiation.

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 capable of resisting electromagnetic radiation 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 the be...
