Description
Technical field
The invention belongs to the comprehensive utilization technique field of crop by-product, with to utilize crop stalk to prepare decoration material field relevant.Specifically, the present invention relates to utilize nano titanium oxide that the cotton bar is carried out modification and handle, adopt the disposable extruding-out process of twin screw, produce cotton stalk finishing material with photocatalyst effect.The invention still further relates to the method for this material of preparation.
Background technology
The annual agricultural crop straw of producing of China has more than 700,000,000 ton, can supply have more than 600,000,000 ton that utilizes.Except that part is used for also field, feed and as the domestic energy utilization, the stalk 50% or more does not obtain development and utilization as yet, the peasant generally burns them as refuse, not only cause the wasting of resources, the environment of having gone back severe contamination; On the other hand, China is per capita in the world forest reserves countries seldom, adds that construction and decoration and furniture industry use timber in a large number, and the area of woods of China reduces year by year, ecotope and human kind sustainable development is caused have a strong impact on.
Existingly in the prior art utilize crop stalk to prepare the report of finishing material: the patent No. is the preparation method that 2608598 Chinese utility model patent discloses a kind of straw decorative sheet; This straw decorative sheet is made up of the straw layer of multilayer farm crop; The mutual cross arrangement of adjacent two layers straw; Every layer of straw is made up of glue bond, utilizes hydropress that one-piece construction is compressed and heating and molding, at last its polishing, pouring lacquer is finished product; Application number is technology and the prescription that 200410016228.6 Chinese invention patent application discloses a kind of high-strength environment-friendly homogeneous plate; Be equipped with isocyanic ester and water after adopting the dedusting of comminuted plants straw; After mixing, carry out paving prefabricating, hot repressing earlier; In temperature is 180 ℃-200 ℃, and hot pressing forms on the thermocompressor of hot pressing pressure 3-4MPa/ unit square; The patent No. is that a kind of method of utilizing crop stalk and husk as raw material to make finishing material has been introduced in 99115722.2 Chinese invention patent application; Its method is to the 5-80 order with raw material pulverizing; Add the isocyanates or the modified isocyanate resin glue that account for total amount 5-20%; Stir back stand is distributed in the structure mould, 80-150 ℃ with 2-15MPa pressure under molded curing.Above patent documentation is batch process owing to adopt hydraulic pressure (mold pressing) moulding process, and the scrap rate of finished product is high, causes production cost high, therefore is difficult to apply.In order to overcome the deadly defect of hydraulic pressure (mold pressing) moulding process, people turn to the use extrusion moulding.Like number of patent application is that 99118206.5 patent of invention documents know clearly openly that a kind of its composition comprises high density polyethylene(HDPE), rice husk and lead stearate to mould the wood filler block plate of Dai Mu, and auxiliary materials such as hard barium, hard calcium are through batching, kneading, extrusion moulding.Because the consistency of straw and resin is poor, the temperature tolerance of straw is poor, the flowability of straw in screw rod is poor, and therefore, straw content is lower in the finished product, and generally below 50%, and performance of products is relatively poor.Defective (production cost is higher, and plate surface is coarse, and color and luster is undesirable) to patent in early stage " a kind of finishing material and preparation method (patent No. ZL200610018378.X) who utilizes rape stalk to make "; The present invention adopts and adds nano TiO 2 in synthesized polymer material; The performance of body material is improved, and nano TiO 2 has the photocatalyst effect simultaneously, is used for tame package material; Give the matrix material bacteria resistance function, make finishing material have environmental protection and antibiotic dual nature.
Summary of the invention
The object of the present invention is to provide and a kind ofly utilize the cotton straw to make to have finishing material for building of environmental protection and antibiotic dual nature and preparation method thereof; To overcome the defective that prior art exists, utilize nano TiO 2 that the cotton straw is carried out the modification processing and adopts the preparation of twin screw expressing technique to have environmental protection and antibiotic dual nature finishing material with photocatalyst effect.
The present invention is a raw material with the cotton stalk; Through adding the synthesized polymer material high density polyethylene(HDPE) as toughener; Adopt twin screw to extrude once through moulding technology, prepare high performance stalk finishing material, like skirting, floor, decorative sheet etc.; Replacing wood is used for industries such as construction and decoration and furniture., stalk technical barriers such as flow difficulties in twin screw extrusion poor to stalk and synthetic macromolecule consistency; Adopt specific single screw extrusion technology, expanded stalk increases percent crystallinity decline, the surface-area of stalk fibre; Be beneficial to the surface-treated of stalk; And the optimization through various processing aids and perfect, and the optimization of manufacturing condition prepares the finishing material of high straw content, high performance-price ratio.The stalk finishing material integrates the advantage of timber and plastics; Appearance of natural wood is not only arranged; And overcome many defectives of timber, and have that the not available flame retardant resistance of timber and anticorrosion, moistureproof, anti-is damaged by worms and advantage such as dimensional stability, do not contain obnoxious flavoures such as formaldehyde.The whole process of production non-environmental-pollution, resource utilization is high, and facility investment is few, and cost is low, extensive market, prospect is considerable.The applicating and exploitation success of present technique with the straw utilization situation of greatly improving present rural area, improves farm crop added values in postpartum such as rape, increases farmers' income; Will be for Wuhan City's " amphitypy " social construction, crack the agriculture, rural areas and farmers problem, and promote the development of Agricultural recycling economy that new concept and new practice are provided.
