Abstract

The invention discloses a bar inserting type heat insulation section material. Raw materials for the section material comprise polyvinyl chloride, high-heat-resistant resin, an impact modifier, a heat stabilizer, a lubricant, a processing aid, an anti-oxidant and a filler. The invention also discloses a preparation method for the bar inserting type heat insulation section material. The bar inserting type heat insulation section material provided in the invention is a novel environment-friendly material and can be used as a heat insulation section material to substitute imported glass fiber reinforced nylon 66. According to the invention, through the procedures of tooth punching, bar inserting and rolling, a bar-like heat insulation material is inserted into a bar inserting groove of an aluminum alloy section and is made to be firmly engaged with the aluminum alloy section, and performances of the bar inserting type heat insulation section material fully satisfy national standard performance requirements on heat insulation sections.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a strip-type heat-insulating profile material and a preparation method thereof. Background technique [0002] The energy-saving broken bridge type aluminum-plastic composite window uses plastic profiles to separate and tightly connect the two layers of aluminum alloys indoors and outdoors into a whole, forming a new heat-insulating plastic-aluminum profile. Using this profile to make doors and windows, Its thermal insulation is at the same level as plastic (steel) windows - the national standard level, which completely solves the fatal problem of aluminum alloy conduction and heat dissipation and does not meet the energy-saving requirements. Alloy push-pull windows are not tightly sealed". The two sides of the product are made of aluminum, and the middle is made of a plastic profile cavity as a thermal insulation material. This innovative structural design takes int...
