Plastic-steel doors and windows

Abstract

The invention provides plastic-steel doors and windows. The plastic-steel doors and windows are prepared from the following components of 75 to 100 parts of polyvinyl chloride resin, 15 to 25 parts of active calcium carbonate, 3 to 10 parts of plant fiber, 5 to 10 parts of flame-retardant agent, 5 to 7 parts of methacrylate-butadiene-styrene copolymer, 20 to 30 parts of water, 3 to 5 parts of nanometer barium sulfate, 5 to 7 parts of MBS (methyl methacrylate) emulsion, 2 to 3 parts of methyl (3,5-di-tert butyl-4-hydroxyphenyl)propionate, 3 to 4 parts of 2-butyne-1,4-diol, 6 to 9 parts of nanometer calcium carbonate, 2 to 3 parts of zinc laurate, 11 to 14 parts of shell powder, 1 to 2 parts of dioctyl adipate, 2 to 4 parts of lubricant, 1 to 2 parts of azodicarbonamide, 1 to 2 parts of sodium bicarbonate, 0.5 to 1 part of sodium bicarbonate, 5 to 15 parts of chlorinated polyethylene, 0 to 10 parts of acrylate anti-impact modifier, 3 to 5 parts of stabilizer and 0 to 1 part of plasticizer. The plastic-steel doors and windows have the advantages that the strength, toughness and anti-aging property are enhanced, the support is convenient, the application range is broad, the size adaptability is strong, the deformation is avoided, and the waterproof property and anti-corrosive property are greatly improved.

Description

technical field [0001] The invention relates to the technical field of door and window materials, in particular to a plastic-steel door and window. Background technique [0002] The materials used to prepare doors and windows in the prior art mainly include several types such as aluminum alloy, stainless steel, and glass fiber composite materials, but the door and window profiles such as aluminum alloy and stainless steel are not corrosion-resistant, and their high heat transfer coefficient makes their comprehensive performance Poor, average energy-saving effect and heavy weight. Although the heat transfer coefficient of glass fiber composite doors and windows is lower, the corrosion resistance and aging resistance of glass fiber composite door and window profiles are poor. Improper use of materials will lead to structural design problems, such as: complex structure, high cost, easy damage and wear between parts, and during the installation process, additional installation ...

[0002] The materials used to prepare doors and windows in the prior art mainly include several types such as aluminum alloy, stainless steel, and glass fiber composite materials, but the door and window profiles such as aluminum alloy and stainless steel are not corrosion-resistant, and their high heat transfer coefficient makes their comprehensive performance Poor, average energy-saving effect and heavy weight

Although the heat transfer coefficient of glass fiber composite doors and windows is lower, the corrosion resistance and aging resistance of glass fiber composite door and window profiles are poor.

Improper use of materials will lead to structural design problems, such as: complex structure, high cost, easy damage and wear between parts, and during the installation process, additional installation tools are required for assembly, the assembly process is cumbersome and stable Poor performance and other issues
