Abstract

The invention discloses an exterior color-mixed nylon powder coating and a preparation method thereof, belonging to the field of preparation of nylon powder coatings. The exterior color-mixed nylon powder coating is formed by mixing nylon powder, pigments and auxiliaries, and the weight ratio of the nylon powder to the pigments to the auxiliaries is 100:(0.1-15):(0.01-15). The preparation method comprises the following steps: firstly, heating the nylon powder with the need of color mixing to 45-60 DEG C through a high-speed mixing machine, then adding the pigments and the auxiliaries according to the weight ratio, performing high-speed mixing, and adhering the pigments to nylon powder particles to prepare the exterior color-mixed nylon powder coating of a target color. According to the preparation method of the exterior color-mixed nylon powder coating, disclosed by the invention, adverse factors of color mixing of a traditional process are overcome, and the preparation method has the advantages of simplicity, easiness in operation, fast color-mixing speed, convenience in cleaning, mass production and test sample preparation; and the prepared exterior color-mixed nylon powder coating has the advantages of uniform color dispersion, dense and firm coating and good using performances.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to an exterior-colored nylon powder coating and a preparation method thereof. Background technique [0002] Nylon powder coating has the characteristics of wide processing temperature range, good wear resistance, low friction coefficient and good adhesion with metal materials, and is widely used in chemical industry, electronics, machinery, automobile industry and other fields. At the same time, as a thermoplastic powder, it has the advantages of saving resources, easy recycling and easy repair, and has become a promising variety in powder coatings. [0003] Nylon powder coating itself is white or natural color, and the color is monotonous. In order to meet the actual application needs of various industries, the color diversification of nylon powder coating can be realized by adding a certain amount of pigment. Combined with the production process of nylon powder coatings, ...
