Abstract

The invention discloses carrier-free color sand grains and a preparation method thereof, which solves the problem that the dispersity of pigments in a polypropylene material is poorer, the coloring is non-uniform and the visual perception of a folding stool is influenced. According to a key point of the technical scheme, the color sand grains are prepared from the following components in parts by weight: 70 to 80 parts of color powder, 5 to 8 parts of polyethylene wax, 5 to 8 parts of ethylene bis stearamide, 3 to 5 parts of acrylic grafted polypropylene wax, 1 to 3 parts of silane coupling agent, and 1 to 3 parts of hyperbranched polyester. The carrier-free color sand grains are relatively good in compatibility with a polypropylene material and good in color developing degree, so that the color sand grains are uniform in coloring.

Description

technical field [0001] The invention relates to a material for a folding stool, in particular to a carrier-free colored sand grain and a preparation method thereof. Background technique [0002] Furniture is a class of utensils for people to sit, lie or support objects in life, work or social practice. All kinds of furniture products not only have the function to meet people's daily needs, but also have a certain artistry, which makes people have a certain aesthetic and spiritual needs in the process of contact and use, that is, both functional and artistic. Heavy features. [0003] However, the living area of ​​modern people is small, and the folding stool has the characteristics of small footprint and convenient use, so it is widely loved by people. A common folding stool is injection molded from polypropylene with color masterbatch and other additives. By adding color masterbatches, the folding stool can show various colors to meet people's daily aesthetic enjoyment. ...
