Problems solved by technology

Among them, glass microspheres are an important raw material for the manufacture of reflective films, but in actual production, due to the polar state of "hydrophilic and oleophobic" on the surface, the compatibility and affinity between them and the polymer matrix Poor, the obvious interface effect with the polymer matrix makes the glass beads agglomerate and other phenomena, which affects the performance of the reflective film and leads to a decline in quality

Abstract

The present invention discloses a glass micro-bead for use in a PP reflection film and a method for preparing same. The glass micro-bead is prepared using the following raw materials based on part by weight: 24 to 42 parts of chabazite, 36 to 54 parts of silica fume, 18 to 36 parts of tridymite, 15 to 30 parts of illite, 22 to 44 parts of polyhalite, 26 to 48 parts of gibbsite, 45 to 60 parts of ceramic waste, 14 to 26 parts of sodium nitrate,12 to 16 parts of dipropylene glycol methyl ether acetat, 10 to 15 parts of ammonium polyacryloyldimethyl taurate, 3 to 6 parts of Jojoba acid polyoxypropylene ester, 4 to 8 parts of Acrylic ester of stearic acid ester, and 14 to 18 parts of additive. The glass micro-beads prepared according to the present invention have high qualification rate, good quality, stable properties, high inverse reflection coefficient, good reflection effect, excellent weather resistance, corrosion resistance and thermal resistance, good durability and wide application prospect.

Description

technical field [0001] The invention relates to a glass microsphere for PP reflective film and a preparation method thereof, belonging to the field of glass microsphere manufacture. Background technique [0002] Reflective film is a film with a special structure that uses optical principles to retroreflect light back to the light source. PP reflective film is an emerging high-performance composite reflective material formed by combining the reflective layer formed by glass beads and PP polymer materials by a special process. Among them, glass microspheres are an important raw material for the manufacture of reflective films, but in actual production, due to the polar state of "hydrophilic and oleophobic" on the surface, the compatibility and affinity between them and the polymer matrix Poor, the obvious interface effect with the polymer matrix makes the glass beads agglomerate and other phenomena, which affects the performance of the reflective film and leads to a decline i...
