Composite material for producing PVC plastic steel section and preparation method thereof

Abstract

The invention belongs to the technical field of door and window materials, and provides a composite material for producing PVC plastic steel sections and a preparation method thereof, wherein the composite material comprises the following raw materials in parts by weight: 160-190 parts of PVC, 2-6 parts of magnesium stearate, 11-13 parts of Phenolic Resin, 15-25 parts of polyethylene wax,-2-9 parts of sodium silicate, 1-4 parts of basalt fiber, 1.2-3.5 parts of forsterite powder, 2-4 parts of an anti-aging agent, 0.2-3.1 parts of a plasticizer, 0.4-2 parts of an additive and 1-2 parts of nano silver. The composite material uses the PVC as a main material, the anti-aging agent is compounded to improve the anti-aging properties of the material, the nano silver is compounded to improve the mildew resistance of the material, the basalt fiber is compounded to improve the mechanical properties and the anti-aging properties of the material, the forsterite powder is compounded to improve the high-temperature resistance, the plasticizer is compounded to make the mechanical properties of the material good, and the aging rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of door and window materials, and in particular relates to a composite material for producing PVC plastic-steel profiles and a preparation method thereof. Background technique [0002] Plastic-steel profiles are referred to as plastic-steel profiles, and the main chemical component is PVC, so it is also called PVC profiles. It is a new type of building material that is widely used. The material has excellent performance, convenient processing and wide use. It is usually used in housing construction for sliding, casement doors and windows, guardrails, pipes and ceiling materials. [0003] The reason why plastic-steel profiles can be widely applied and gradually replace wooden and aluminum doors and windows is inseparable from its unique advantages. It has the following advantages: [0004] 1. Durable: It has the effect of shock resistance, wind erosion resistance and long service life. The addition of anti...
