Light plastic door and window

Abstract

The invention discloses a light plastic door and window which is prepared from the following raw materials in parts by mass: 6-10 parts of sisal fiber, 60-70 parts of a 20-30% sodium hydroxide solution, 30-41 parts of dimethyl carbonate, 2-3 parts of op-10, 20-30 parts of n-butyl acrylate, 0.4-0.6 part of ammonium persulfate, 60-70 parts of vinyl acetate, 36-40 parts of benzyl chloride, 400-430 parts of polyvinyl chloride, 2-4 parts of polyvinyl butyral, 6-8 parts of dibutyl maleate, 2-4 parts of chitosan, 4-7 parts of boron, 0.4-1 part of hexabromocyclododecane, 2-4 parts of sodium antimonate, 10-17 parts of scolecite, 3-5 parts of potassium pyrophosphate, 31-40 parts of light calcium carbonate and 3-5 parts of palm wax. According to the light plastic door and window disclosed by the invention, the sisal fiber is treated by microwaves to improve the dispersibility of cellulose, so that the accessibility of benzyl chloride to cellulose is increased; after etherification treatment, the quantity of hydroxyl is reduced, and cellulose crystalline texture is damaged to obtain thermoplasticity.

Description

technical field [0001] The invention mainly relates to the field of plastic doors and windows, in particular to a lightweight plastic door and window. Background technique [0002] Plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (glass fiber reinforced plastic) doors and windows according to the material. Among all kinds of building windows, PVC plastic windows are outstanding in saving energy consumption in profile production, reusing recycled materials and using energy consumption. Advantages, excellent performance-price ratio in terms of heat preservation and energy saving. In order to increase the rigidity of the window, in the stressed members of the window frame, sash, and stile sections, it should be determined which reinforced steel to use according to the design of the wind pressure resistance and other service requirements. Through the co-extrusion of UPVC resin and colored polymethyl methacrylate (PMM...
