Abstract

The invention provides an acrylic protective paint for a helmet. The acrylic protective paint comprises 30-40 parts by mass of aqueous acrylic resin A and 10-20% by mass of aqueous acrylic resin B; wherein, the aqueous acrylic resin A has a glass transition temperature of 100 DEG C to 110 DEG C, the aqueous acrylic resin B has THE glass transition temperature of 50 DEG C to 60 DEG C, and the aqueous acrylic resin B is a vinyl chloride / N-substituted maleic amine / acrylic acid copolymer resin. The acrylic protective paint for the helmet has the advantages of fast drying, good adhesion, good impact resistance, good weather resistance, low toxicity and low VOC emission.

Description

technical field [0001] The present invention generally relates to the field of coatings, and in particular, relates to an acrylic protective paint for helmets and a preparation method thereof. Background technique [0002] With the development of modern science and technology and modern industry, environmental pollution has caused a great threat to the earth on which people live and human beings themselves. Traditional coatings emit a large amount of toxic and harmful waste gas and waste water during the manufacturing process, which pollutes the environment, the atmosphere and water resources. Especially for solvent-based coatings, more than 50% of volatile organic compounds (VOC) are discharged into the atmosphere during construction, causing Secondary pollution. [0003] The replacement of polluting materials by non-polluting and low-polluting materials is the need of human existence. Coatings that do not emit VOC or whose emissions are strictly limited below the specifie...
