Embodiment 1

[0017] A preparation method for a plastic door frame, wherein the preparation method comprises: mixing 100g polyvinyl chloride, 40g polyethylene, 20g polyamide, 10g phenolic resin, 10g filler, 1g plasticizer and 1g anti-aging agent to form a mixture M ; The mixture M was melted (the melting temperature was 200°C, and the time was 10 minutes) and added into a molding mold, water-cooled (the temperature of the cooling water was 5°C) and molded to obtain the plastic door frame A1.

Embodiment 2

[0019] A preparation method for a plastic door frame, wherein the preparation method comprises: mixing 100g polyvinyl chloride, 60g polyethylene, 30g polyamide, 20g phenolic resin, 15g filler, 5g plasticizer and 3g anti-aging agent to form a mixture M ; Melt the mixture M (the melting temperature is 250°C, the time is 20min) and add it into the molding mold, water cooling (the temperature of the cooling water is 10°C) and then molding to obtain the plastic door frame A2.

Embodiment 3

[0021] A preparation method for a plastic door frame, wherein the preparation method comprises: mixing 100g polyvinyl chloride, 50g polyethylene, 25g polyamide, 15g phenolic resin, 12g filler, 3g plasticizer and 2g anti-aging agent to form a mixture M ; Melt the mixture M (the melting temperature is 220°C, and the time is 15 minutes) and add it into the molding mold, water cooling (the temperature of the cooling water is 7°C) and molding to obtain the plastic door frame A3.

Abstract

The invention discloses a plastic doo frame and a making method thereof. The method comprises the following steps: mixing polyvinyl chloride, polyethylene, polyamide, phenolic resin, a filler, a plasticizer and an antioxidant to form a mixture M; and melting the mixture M, adding the molten mixture M into a molding die, and carrying out cooling molding to obtain the plastic doorframe. The problems of yellowing, cracking and easy deformation caused by long-time sunlight irradiation of common plastic doorframes are solved in the invention.

Description

technical field [0001] The invention relates to the preparation of a door frame, in particular to a plastic door frame and a preparation method thereof. Background technique [0002] Among all kinds of building windows, plastic windows have outstanding advantages in saving energy consumption in profile production, reusing recycled materials and using energy consumption, and have excellent performance-price ratio in terms of heat preservation and energy saving. Plastic door frames have excellent wind pressure resistance, water tightness and air tightness, but ordinary plastic door frames will turn yellow and crack after prolonged exposure to the sun, and are easily deformed. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a plastic door frame that will not appear yellowing and cracking after long-term exposure to the sun, and is not easily deformed and its preparation method. Contents of the invention [0004] The technical prob...
