Description

A kind of ornament materials and preparation method who utilizes rape straw to make
Technical field
The invention belongs to the comprehensive utilization technique field of crop by-product, and utilize crop stalk to prepare building decorative or field of packaging material is relevant.Specifically, the present invention relates to utilize nano material that rape straw is carried out modification and handle, adopt twin-screw expressing technique and disposable modification and the moulding of finishing rape straw of equipment.The invention still further relates to the method for this material of preparation.
Background technology
As everyone knows, China is the big producing country of timber and woodwork in the world, also is a consumption big country, is again per capita forest reserves countries seldom simultaneously, adds indiscriminate felling of trees, and the area of woods of China is reduced year by year.The minimizing of forest and surface vegetation not only can cause ploughing and degenerate and climate change, also will cause the ecological balance to have a strong impact on.Industries such as building, decoration, furniture are used timber in a large number, are the fields of lumber consumption maximum, also are to cause the forest reserves by the main cause of heavy damage.Therefore, the substitute of searching timber is one of outlet that solves forest reserves crisis.
Rape is one of large agricultural product of China, and rapeseed is except that being used to process the grease, and remaining accounts for these valuable resources of byproduct such as the non-edible part of rape about 80% such as rape straw, rape pod, rapeseed hull and is is effectively develop and useedd as yet.Because rape straw, rape pod, rape shell etc. contain abundant cellulose, has certain intensity and toughness, after certain modification processing, can replace plastic resin and timber, be used to make disposable tableware, packaging material, goods, various ornament materials or packaging material (skirting, the floor perhaps be used to build, industry such as decoration, furniture being used, automotive trim panel and back are every ornament materials) etc., be the substitute of good plastic raw materials and timber.So both realized agricultural resource comprehensive utilization, improved rape processing back byproduct added value, increase farmers' income, can alleviate " white pollution " that plastics cause preferably again.The product of this new material manufacturing has dimensionally stable, do not ftracture, warpage and do not contain advantages such as pernicious gas such as formaldehyde not, has tangible economy, society and ecological benefits.
Existingly in the prior art utilize crop stalk to prepare the report of ornament materials: the patent No. is the preparation method that 2608598 Chinese utility model patent discloses a kind of straw decorative panel, this straw decorative panel is made of the straw layer of multilayer crops, the mutual cross arrangement of adjacent two layers straw, every layer of straw is made of glue bond, utilize hydraulic press that overall structure is compressed and the typing of heating, at last its polishing, leaching paint are 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 isocyanates and water after adopting the dedusting of comminuted plants straw, after mixing, carry out paving prefabricating earlier, hot repressing, in temperature is 180 ℃-200 ℃, and hot pressing forms on the hot press 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 ornament materials 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 binder that account for total amount 5-20%, stir back stand is distributed in the structure mould, molded curing under 80-150 ℃ and 2-15MPa pressure.Above patent documentation is batch process owing to adopt hydraulic pressure (mold pressing) moulding process, and the percent defective height of finished product causes the production cost height, 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.As 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 molding.Because the compatibility 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 final products, generally below 50%, and the poor-performing of product.
Nano level silica (SiO 2) be unformed white powder, its molecular state is tridimensional network.Because the hydroxyl that size is little, specific area is big, the surface energy is high, the surface exists a large amount of undersaturated residual bonds and different bonding states easily is distributed in the space of macromolecular chain again simultaneously.So be used for the straw fiber of modified polyhydroxy, can improve resistance to water and the MOR and the toughness of product greatly.By retrieval, have not yet to see the relevant nanometer SiO that utilizes 2Material carries out the report that ornament materials was handled and was used to make in modification to rape straw.
Summary of the invention
The object of the present invention is to provide a kind of rape straw that utilizes to make new decorative material for building or packaging material and preparation method thereof, to overcome the defective that prior art exists, utilize nano material that rape straw modification processing and employing twin-screw expressing technique are prepared novel environment friendly building or wrapping ornament materials, rape straw modification in the present invention and moulding are finished in same equipment, to reach effective utilization of rape straw.
The present invention realizes by following technical proposal:
A kind of ornament materials that utilizes rape straw to make, Ji component and content are as follows by weight:
In water content is that 3% rape straw powder is a radix for 100 parts:

2) will dry to water content is that 3% rape stalk is crushed to 80 orders, pours in 90 ℃ the homogenizer and mixes, and adds two amino silanes described rape straw was carried out modification 10 minutes, obtains modified product;
3) nano silicon, the step 2 that step 1) is obtained) modified product, high density polyethylene (HDPE), talcum powder, paraffin, haloflex, ethylene propylene diene rubber and the Celogen Az that obtains places 110 ℃ of high-speed mixers, mixed 15 minutes, and obtained mixed material;
4) mixed material that step 3) is obtained places double screw extruder to extrude, each section heating-up temperature T1-T6 is respectively 90 ℃, 124 ℃, 154 ℃, 150 ℃, 132 ℃ and 125 ℃, 93 rev/mins of engine speeds, main frame electric current 92A, material are pressed 1.8MPA, are finished product through mould shape, cooling, traction, cutting.
2, the described a kind of method of utilizing rape straw to prepare ornament materials of claim 1, it may further comprise the steps:
1) nano silicon with described sodium trimetaphosphate and particle diameter 50nm mixes in the ball mill barrel that drops into 45r/min in the back, and described nano silicon is fully disperseed;
2) will dry to water content is that 3% rape stalk is crushed to 80 orders, pours in 90 ℃ the homogenizer and mixes, and adds two amino silanes described rape straw was carried out modification 10 minutes, obtains modified product;
3) nano silicon, the step 2 that step 1) is obtained) modified product, high density polyethylene (HDPE), talcum powder, paraffin, haloflex, ethylene propylene diene rubber and the Celogen Az that obtains places 110 ℃ of high-speed mixers to mix 15 minutes, obtains mixed material;
4) mixed material that step 3) is obtained is put in the double screw extruder and is extruded, each section heating-up temperature T1-T6 is respectively 90 ℃, 124 ℃, 154 ℃, 150 ℃, 132 ℃ and 125 ℃, 93 rev/mins of engine speeds, main frame electric current 92A, material are pressed 1.8MPA, are finished product through mould shape, cooling, traction, cutting.
