Oxidation resisting calcium carbonate filler and preparation method thereof

Abstract

An oxidation resisting calcium carbonate filler is prepared from the following raw materials in parts by weight: 1-2 parts of ammonium polyphosphate, 1-2 parts of ASA, 1-2 parts of cyclohexanone, 0.4-0.8 part of epoxy soja bean oil, 0.8-1.1 parts of zinc diricinoleate, 1.5-1.8 parts of dimethyl maleate, 1.5-1.8 parts of bismaleimide resin, 0.1-0.2 part of lauric acid polyoxyethylene esters, 2.6-2.9 parts of dibutylhydroxytoluene, 3-5 parts of alcohol, 20-30 parts of modified wood meal, 180-200 parts of light calcium carbonate, and 60-80 parts of water. The oxidation resisting calcium carbonate filler provided by the invention has excellent oxidation resistance, and can reinforce oxidation resistance and weather resistance of a plastic; through adoption of the modified wood meal, the oxidation resisting calcium carbonate filler is compatible with PVC, and can reinforce heat preservation performance, shock resistance and coloration properties of the plastic; the oxidation resisting calcium carbonate filler is suitable for manufacturing of doors and windows of PVC and other plastics, can reduce the cost, improve machining property, and prolong service life, is recycled easily, and can protect the environment.

Description

technical field [0001] The invention belongs to the field of calcium carbonate fillers, in particular to an oxidation-resistant calcium carbonate 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.

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
