Heat-preservation plastic door and window filler and preparation method thereof

Abstract

The invention discloses heat-preservation plastic door and window filler. The heat-preservation plastic door and window filler is prepared from the following raw materials in parts by weight: 1-2 parts of tetraoctyl ammonium bromide, 0.5-0.8 part of mercapto carboxylic acid, 1-2 parts of polyethylene glycol, 3-4 parts of nano-level titanium dioxide sol, 3-4 parts of hollow glass micro-spheres, 2-3 parts of hollow borosilicate micro-spheres, 0.7-1 part of nitrilotriacetic acid, 20-30 parts of modified saw dust, 180-200 parts of light calcium carbonate and 60-80 parts of water. Calcium carbonate filler disclosed by the invention is subjected to surface modification, has excellent reinforcing performance, can be well compatible with PVC, and can be used for increasing the strength of plastic doors and windows; the heat preservation performance of the plastic doors and windows can be increased by adopting the hollow glass micro-spheres and the hollow borosilicate micro-spheres; and by adopting the modified saw dust, the filler has good compatibility with PVC, and the heat preservation performance, impact resistance and coloring performance of the doors and windows can be increased.

Description

technical field [0001] The invention belongs to the field of calcium carbonate fillers, in particular to a thermal insulation plastic door and window filler and a preparation method thereof. Background technique [0002] Plastic doors and windows, that is, doors and windows made of U-PVC plastic profiles. Plastic doors and windows have good characteristics such as wind resistance, waterproof, and heat preservation. [0003] The current plastic doors and windows include PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows. Among all kinds of building doors and windows, PVC plastic doors and windows have outstanding advantages in saving energy consumption in profile production, reusing recycled materials and using energy consumption, and have excellent performance-price ratio in terms of heat preservation and energy saving. [0004] When making plastic doors and windows, fillers are needed. At present, calcium carbonate fillers are mostly ...

AI Technical Summary

Problems solved by technology

[0004] When making plastic doors and windows, fillers are needed. At present, calcium carbonate fillers are mostly used, but calcium carbonate has strong hydrophilicity, and its surface properties need to be improved to increase its compatibility with plastics and increase reinforcement performance. , the performance of the current modified calcium carbonate is not good enough; there is also a single calcium carbonate filler that cannot meet the requirements for performance improvement
