Problems solved by technology

[0005] The technical problem to be solved by the present invention: the current common polypropylene sheet has poor wear resistance, low impact strength, poor aging resistance, and is easy to burn. The compatibility of inorganic fillers is poor, which limits its application as raw materials or special materials for injection molding, fibers, films and other products, and provides a preparation method for nano-modified polypropylene sheets

Embodiment Construction

[0024]Weigh 75-85g of polypropylene and heat up to 165-175°C to soften it, add 2-4g of antimony trioxide and 3-5g of red phosphorus to the softened polypropylene in turn, continue to keep warm and mix and stir for 35-45min to obtain Modified polypropylene melt; Weigh 11-13g sycamore leaves and place them in a beaker with 40-45mL deionized water, and place the beaker in an ultrasonic oscillator at a temperature of 65-70°C and a frequency of 10- Under the condition of 12kHz, ultrasonically extract for 16-20min, remove the filter residue by filtration, collect the filtrate, and distill the filtrate under reduced pressure for 8-10min to obtain the self-made plant extract. The extracts were mixed and placed in an ultrasonic disperser, and ultrasonically dispersed for 16-20 minutes under the conditions of power 85-100W and frequency 4-6kHz to obtain a modified polypropylene dispersion; measure 16-20mL butyl titanate and dissolve in Put in a beaker with 75-80mL of absolute ethanol an...

Abstract

The invention relates to the technical field of polymer composite materials, in particular to a preparation method of a nano modified polypropylene board. The preparation method has the advantages that the nano modified polypropylene board is prepared by using molten modified polypropylene as the base material, modified nano mixed powder dispersion liquid and modified basalt fibers as the modifiers and maleic anhydride grafted polypropylene, calcium carbonate, citric acid and the like as auxiliaries; the polypropylene is modified first, then the maleic anhydride grafted polypropylene is addedinto the polypropylene, a hydroxide solution is used to perform surface modification on the basalt fibers to enhance the affinity of the basalt fibers with nano particles, butyl titanate and anhydrousethanol are subjected to mixing and stirring reaction under the effect of a stabilizer to obtain gel, plant liquid is extracted from phoenix tree leaves, nano zinc oxide powder is evenly dispersed onthe surface of nonpolar base material under a polar adsorption effect so as to lower ultraviolet strength in the irradiation direction, the aging resistance of the polypropylene board is further increased, and promising application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of polymer composite material preparation, in particular to a method for preparing a nano-modified polypropylene plate. Background technique [0002] Polypropylene (PP) is a thermoplastic resin obtained by polymerizing propylene. Polypropylene (PP) sheet is a plastic sheet made of PP resin with various functional additives through extrusion, calendering, cooling, cutting and other processes. Polypropylene sheet is odorless, non-toxic and tasteless in line with national health standards. It has a low density and is the lightest type of general-purpose plastic. It can be used without deformation for a long time at 100 ° C. It also has excellent electrical insulation properties and chemical stability. It hardly absorbs water, and has no effect in contact with most chemicals. At present, polypropylene sheet has been widely used in various fields of packaging and daily life such as industry, agriculture, medica...
