Embodiment Construction

[0011] A wear-resistant high-toughness polyester nitrile rubber composite powder coating, the powder coating is made of the following raw materials in parts by weight: polyester resin chip 50, liquid nitrile rubber 10, hyperbranched polyester 8, cashew nut shell oil friction Powder 4, polyether modified silicone oil 3, hydroxyalkylamide 3, pigment 5, zinc stearate 1, silane coupling agent kh560 0.4, vulcanizing agent PDM 0.1.

[0012] The preparation method of described a kind of wear-resistant high-toughness polyester nitrile rubber composite powder coating, described preparation method comprises the following steps:

[0013] (1) Mix, grind and disperse the cashew nut shell oil friction powder and silane coupling agent kh560 for 20 minutes, and then set aside;

[0014] (2) Put the material obtained in step (1) into a high-speed mixer together with other remaining raw materials to stir and mix evenly, then send the material into a twin-screw extruder, extrude and granulate at ...

Abstract

The invention discloses a wear-resistant high-tenacity polyester-butadiene acrylonitrile rubber composite powder coating. Polyester resin and liquid butadiene acrylonitrile rubber are compounded, so that hole shrinking and cracking of a coating when hydroxyalkyl amide is used as a curing agent are improved effectively, and adhesive power between the coating and metal materials is improved; by adding hyperbranched polyester, compatibility among macromolecules is effectively improved, and tenacity of a composite material is improved; cashew nut shell oil friction powder after being modified by a silane coupling agent kh560 is higher in dispersibility, friction performance of the coating can be adjusted, and retentivity can be improved; other raw materials are combined, and the composite powder coating having good film forming performance and using performance is prepared finally. The composite powder coating is nontoxic, odorless, skid-resistant, wear-resistant, high in tenacity, cracking-resistant, high in adhesive power with a metal substrate and less prone to scaling and shedding, and using experience in outdoor environment is improved effectively while service life is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of outdoor powder coatings, in particular to an anti-wear and high-toughness polyester-nitrile rubber composite powder coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, fitness and amusement equipment, as a multifunctional equipment integrating fitness and entertainment, can be seen everywhere in residential areas, squares and other places. Most of the equipment itself is made of metal materials, and the surface is sprayed with paint. Since the fitness and amusement equipment directly contacts the human body, and most of the users are the elderly and children, the environmental protection of the paint is also very important. Water-based paint is an environmentally friendly Coatings with high corrosion resistance have been widely concerned, but water is easy to corrode metal, so it is not suitable for coating on metal materials. In addition, fitn...
