The invention discloses an organosilicone reinforced plastic door or window. The organosilicone reinforced plastic door or window comprises, by weight, 300-350 parts of polyvinyl chloride, 60-70 parts of 20-30% sodium hydroxide solution, 36-40 parts of benzyl chloride, 40-42 parts of divinylbenzene, 70-80 part of styrene, 0.3-0.6 part of benzoyl peroxide, 2-3 parts of alpha-bromocinnamaldehyde, 3-4 parts of urea, 10-12 parts of tetraethoxysilane, 6-8 parts of polytetrafluoroethylene wax, 30-45 parts of expanded perlite, 4-7 parts of stearic acid, 2-4 parts of magnesium carbonate, 20-24 parts of superfine barium sulfate, 4-5 parts of pentaerythritol and 1-2 parts of Span 80. Sisal fibers are treated in a freezing swelling mode, the dispersity of cellulose is improved, the accessibility of the benzyl chloride to the cellulose is improved, the number of hydroxyl groups is reduced after etherification treatment is carried out on the cellulose, the crystalline texture of the cellulose is destroyed to obtain thermoplasticity, and the dimensional stability, the weather fastness and the corrosion resistance of the fibers are improved correspondingly.
