Abstract

The invention discloses a polyethylene material for thermoplastic powder coating, which mainly consists of 70-90 parts of linear low-density polyethylene, 5-15 parts of ethylene-octene copolymer and 5-15 parts of ethylene-vinyl acetate copolymer. The invention also discloses a preparation method of the polyethylene material. The polyethylene material has the characteristics of good resistance to environmental stress cracking, good leveling effect, and strong adhesion. The powder coating of the powder coating produced by it is smooth and can be used in outdoor environments for a long time.

Description

technical field [0001] The invention relates to a polyethylene modified material, in particular to a polyethylene material used for thermoplastic powder coatings. The invention also relates to a method for preparing the polyethylene material. Background technique [0002] Polyethylene powder coating is an environmentally friendly coating with non-toxic and anti-corrosion characteristics. At present, the most used raw material for domestic thermoplastic powder coatings is low-density polyethylene produced by high-pressure tubular method. The low-density polyethylene produced by this low-density polyethylene Powder coatings have poor resistance to environmental stress cracking, and are prone to cracking in outdoor environments, which affects the performance of the coating. [0003] Linear low density polyethylene (LLDPE) is non-toxic, tasteless, odorless milky white particles with a density of 0.918-0.935g / cm 3 . Compared with LDPE, it has a higher softening temperature and...
