Abstract

The invention discloses thermoplastic fiber elastic plastic doors and windows. The thermoplastic fiber elastic plastic doors and windows are composed of the following raw materials by weight: 400 to 420 parts of polyvinyl chloride, 7 to 10 parts of sisal fibers, 60 to 70 parts of a sodium hydroxide solution with a concentration of 20 to 30%, 30 to 41 parts of dimethyl carbonate, 2 to 3 parts of op-10, 20 to 30 parts of n-butyl acrylate, 0.4 to 0.6 part of ammonium persulfate, 60 to 70 parts of vinyl acetate, 36 to 40 parts of benzyl chloride, 3 to 4 parts of potassium zirconium carbonate, 4 to 5 parts of alkenyl succinic anhydride, 7 to 10 parts of poly(1,2-propylene glycol adipate), 50 to 60 parts of wollastonite powder and 1 to 2 parts of tea saponin. According to the invention, through microwave treatment of the sisal fibers, dispersibility of cellulose is improved, and accessibility of benzyl chloride to the cellulose is increased; the number of hydroxyl groups is reduced after etherification treatment, and a crystal structure of the cellulose is destroyed, so that thermoplasticity is obtained; meanwhile, since the number of the hydroxyl groups is reduced, fiber is correspondingly enhanced in size stability, weather resistance, corrosion resistance, etc.

Description

A kind of thermoplastic fibre plastelast door and window

Technical field

The present invention relates generally to plastic door-window field, particularly relates to a kind of thermoplastic fibre plastelast door and window.

Background technology

Plastic door-window can be divided into PVC plastic door and window and glass filament reinforced plastics (glass reinforced plastic) door and window by material, wherein in all kinds of building window, PVC plastic window repeats there is outstanding advantage in recycling and Energy in use at saving section bar production energy consumption, reclaimed materials, has the excellent ratio of performance to price in heat preservation energy-saving.For increasing the rigidity of window, in the stressed member of window frame, sash, stile's section bar, according to the design of wind pressure resistant strength and other service requirements, should determine to use which kind of enhanced type steel.By the coextrusion of UPVC resin and painted polymethylmethacrylate (PMMA) or acrylonitrile-styrene-acrylic ester copolymer (ASA), and overlay film, spraying can obtain the decorative effect of multiple texture and kinds of surface color on white section bar.In addition the mass coloration technology adding coloring material for mixing and extrude in UPVC resin-oatmeal is also had.But different views are still had to this technology, therefore should be prudent especially when selecting, the colour-change situation of this kind of section bar after artificial accelerated aging test be checked.Suggestion covers same color film to improve its weathering resistance on mass coloration section bar.

At global energy growing tension, under the pressure that environment constantly worsens, biological material is due to the feature of environmental protection and functional outstanding great attention also more and more causing people, reproducible biomass resource is converted into the important trend that consumption that novel material carrys out alternative Nonrenewable resources is nowadays social construction and development, the present invention is then with the additive of sisal fibers as plastic door-window, can play and economize on resources, and the good net effect of reinforced plastics door and window overall performance.
