Door and window sealing material and preparation method thereof

Abstract

The invention discloses a door and window sealing material which is prepared from the following raw materials in parts by weight: 30 to 50 parts of PVC resin, 15 to 25 parts of epoxy resin, 5 to 13 parts of polyisobutene, 2 to 8 parts of fumed silica, 7 to 18 parts of dibutyl phthalate, 5 to 10 parts of filler, 2 to 4 parts of paraffin, 1 to 2 parts of magnesium oxide, 3 to 5 parts of zinc oxide, 1.5 to 2.5 parts of ultraviolet absorbent, 0.1 to 0.5 part of light stabilizer, 0.3 to 0.7 part of stearic acid, 0.2 to 0.6 part of carbon black, 0.5 to 4 parts of titanium dioxide and 0.2 to 3 parts of photocatalyst. The door and window sealing material has no toxicity or odor, has good high temperature resistance, good low temperature resistance and excellent sound insulation effect and has functions of removing formaldehyde, deodorizing, resisting pollution, purifying air and the like.

Description

technical field [0001] The invention belongs to the technical field of doors and windows, and in particular relates to a door and window sealing material and a preparation method thereof. Background technique [0002] At present, most of the sealing materials used in automobiles, aluminum alloys, and plastic steel doors and windows are traditional materials. The deficiencies of these sealing materials are more obvious: short service life, poor high temperature resistance and low temperature performance, fast aging speed, and peculiar smell, easy to crack, etc. For this reason, those skilled in the art have developed multiple improved materials, but, after The trial effect is still not good, especially in the situation that people's living standards are constantly improving and environmental protection requirements are gradually increasing. The market for sealing materials for high-end cars, high-grade aluminum alloys, and plastic steel doors and windows is in urgent need of ...

Problems solved by technology

The deficiencies of these sealing materials are more obvious: short service life, poor high temperature resistance and low temperature performance, fast aging speed, and peculiar smell, easy to crack, etc. For this reason, those skilled in the art have developed multiple improved materials, but, after The trial effect is still not good, especially in the situation that people's living standards are constantly improving and environmental protection requirements are gradually increasing. The market for sealing materials for high-end cars, high-grade aluminum alloys, and plastic steel doors and windows is in urgent need of a non-toxic, tasteless, high-temperature resistant And sealing material with good low temperature resistance and good sound insulation effect
