Embodiment 3

[0031] Preparation method of weather-resistant polyester powder coating modified by inorganic nanocomposite material:

[0032] 1. Weigh the nanocomposite material with a particle size of 10-100nm;

[0033] 2. Mix the nanocomposite material weighed above with filler, polyester resin, curing agent, auxiliary agent, etc. in a high-speed mixer;

[0034] 3. The mixed material is transported to the screw extruder by a feeder for melting and mixing, pressed into thin slices by a tablet press, cooled, crushed by a crusher, and then transported to an air classifying mill (ACM) for fine grinding. The cyclone separator collects most of the crushed semi-finished products, and then the finished powder coating is obtained after the sundries and coarse powder are removed by the sieving machine, and then packed.

Abstract

An inorganic nano composition modified weatherable polyester powder paint is prepared from nano-class inorganic composition, solidifying agent, assistant, filler and polyester resin through premixing, fusing-extruding-mixing, cooling, breaking, pulverizing and sieving. Its advantages are high anti-ageing power, hardness, adhesion and impact strength.

Description

1. Technical field [0001] The invention relates to a weather-resistant polyester powder coating modified by an inorganic nanocomposite material and a preparation method thereof, belonging to the field of powder coating preparation. 2. Background technology [0002] US Patent No. 5759746, Fabrication process using a multi-layer antireflective layer, reports the preparation of an assembly antireflective coating technology with nano-silicon dioxide added on semiconductor integrated circuit boards. This technology is mainly to prevent some semiconductor integrated circuit boards from For example, a kind of protective layer provided by the influence of ultraviolet rays on the etching performance of circuit boards in semiconductor memory and lithography technology; Japanese patent 10-330937, Formation of substantially flat coating has reported the preparation of a super-smooth coating used on superconducting integrated circuit boards Coating technology, a small amount of nano oxid...
