Abstract

The invention discloses a PVC plastic steel profile. The PVC plastic steel profile is prepared from, by weight, 150-200 parts of PVC, 30-50 parts of calcium stearate, 20-35 parts of stearic acid, 15-25 parts of polyethylene wax, 15-20 parts of DOP, 5-15 parts of titanium dioxide, 15-20 parts of paraffin and 6-15 parts of TPP. The preparation method includes the following steps that (1) the PVC, the calcium stearate, the stearic acid, the polyethylene wax, the DOP, the titanium dioxide, the paraffin and the TPP are weighed according to the formula to be evenly mixed; (2) the mixture obtained after even mixing is fed into a parallel twin-screw extruder for melt blending and pelleting, the temperature of a machine cylinder of the extruder is 170-185 DEG C, and the temperature of a die head is 180-200 DEG C; then a conical twin-screw extruder is adopted for extrusion forming, and accordingly formed plastic steel is obtained; the temperature of a machine cylinder of the extruder is 170-185 DEG C, and the temperature of a die head is 180-200 DEG C; (3) the formed plastic steel is cooled and shaped, so that the plastic steel profile is obtained. The PVC plastic steel profile is good in thermal insulation property, durable in use, environmentally friendly, resistant to corrosion and excellent in ageing resistance.

Description

technical field [0001] The invention belongs to the technical field of household production, and in particular relates to a PVC plastic-steel profile and a preparation method thereof. Background technique [0002] Plastic steel profiles are referred to as plastic steel, and the main chemical composition is PVC, so they are also called PVC profiles. It is a new type of building material that is widely used. This material has excellent performance, convenient processing and wide application. Due to its physical properties such as rigidity, elasticity, corrosion resistance, and excellent aging resistance, it is usually used as copper, zinc, aluminum, etc. Good substitute for non-ferrous metals. In housing construction, it is mainly used for push-pull, casement doors and windows, guardrails, pipes and ceiling materials. Plastic steel profiles are made of PVC resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc...
