Abstract

The invention provides a composite thermal insulating strip for building doors and windows and a preparation method of the composite thermal insulating strip, and relates to the field of thermal insulation strips. The composite thermal insulating strip comprises the following raw materials in parts by weight: 75-80 parts of nylon resin, 10-15 parts of epoxidized soybean oil, 5-9 parts of epoxidized fatty acid methyl ester, 5-9 parts of a propylene-ethylene grafted copolymer, 15-20 parts of glassfiber, 15-20 parts of sepiolite fiber, 8-15 parts of basalt fiber, 7-12 parts of nanometer titania,8-12 parts of nano mica powder, 3-7 parts of color master batch, 3-7 parts of phosphate ester, 2-5 parts of sub phosphate ester, 1.8-2.8 parts of an antioxidant, 2.5-4.2 parts of a lubricant, and 1.2-2.5 parts of a silane coupling agent. Through the synergistic effect of raw material components, the composite thermal insulation strip has the advantages that the mechanical toughness is high, the tensile resistance and the break resistance are high, the heat conductivity coefficient is low, and the composite thermal insulating strip has high thermal insulation resistance and durability.

Description

technical field [0001] The invention belongs to the field of heat insulation strips, in particular to a composite heat insulation strip for building doors and windows and a preparation method thereof. Background technique [0002] Designing a house with good thermal insulation is the goal of all architectural designs, whether domestic or industrial, not only for the comfort of people, but also to comply with the legal requirements for energy conservation in the country in which they are located. The heat insulation of doors and windows in building insulation is the focus of energy-saving design. [0003] According to the statistics of the 2012 year-end report of the my country Construction Metal Structure Association, at present, aluminum alloy doors and windows still occupy a dominant position in the market in the country. The above is the use of strip-type heat-insulating aluminum profiles. The strip-threaded heat-insulating aluminum profiles are compounded through the pro...
