Description
Technical field
The present invention relates to a kind of straw processing method, particularly to the manufacture method of a kind of rice straw composite fiber.
Background technology
China's annual agricultural crop straw yield reaches more than 700,000,000 tons, but these resources, and depolarization is on a small quantity with for most outside feedstuff
Being incinerated, this not only causes the huge waste of resource but also causes serious environmental pollution.The content of cellulose of rice wheat straw is about
Being 40%, cellulose is one of Renewable resource the abundantest on the earth, and has inexpensive, degradable and do not produce ecological environment
The advantages such as raw pollution, can be widely used for the works such as papermaking, plastics, alcohol fuel, medicine, food, building materials, pottery, oil, weaving
Industry.Hence with rice wheat straw making cellulose is to reduce to pollute, and improves the effective way of crops economic worth.
Patent CN 102212582 B discloses a kind of method that bioanalysis prepares cellulose from straw.It is by straw
Dedusting, it is crushed to 20-40 mesh, adds in reaction tank, be subsequently adding the water of straw weight 4-5 times, soak 1 hour laggard height
Dense mill defibrination；It is added to after defibrination in retort, adds compound bio catalyst, after mix homogeneously, be warming up to 60-80 DEG C, instead
Answer 1-3 hour；Obtaining unscreened stock after blowing after impurity is removed in screening, unscreened stock enters low dense mill defibrination, is then dehydrated through press master,
Discongest with fluffer again, enter roller drier and be dried, carry out after drying pulverizing to obtain stalk cellulose.Present invention straw
Stalk is that cellulose prepared by raw material, extracts cellulose than traditional handicraft and reduces cost 50%, and bioanalysis is pollution-free, zero-emission, protection
Environment.Patent CN 101314925 B discloses the preparation method of a kind of stalk composite fiber material for road, and this preparation method is
By straw through pulverizing, alkalization, fiber pulp after steaming and decocting with bentonite after levigate, receiving, chemical modification and purification
The bentone soil paste obtained is combined, and the complex fiber material prepared such as separated, dry.
The method step more than making cellulose is complicated, and the cellulose prepared is of poor quality, intensity is low, impurity
More, range of application is little it is thus desirable to need a kind of step easy, can obtain high-quality composite fibre making side
Method.
Summary of the invention
It is an object of the present invention to provide the composite fibre manufacture method that a kind of step is easy, making step is simple, energy consumption is low, system
The composite fibre density obtained is little, intensity is high, high temperature resistant, Heat stability is good, impurity are few, purposes is wide.
The technical scheme is that for achieving the above object
The manufacture method of a kind of rice straw composite fiber, comprises the steps:
A. rice straw is selected materials cleaning: collect new harvesting or the rice straw in the term, removes rice straw mouldy, that rot,
Clean the earth on straw and impurity；
B. dry: the rice straw after cleaning carries out being exposed to the sun or drying；During drying, drying temperature is 45 DEG C-55 DEG C, dries
Time is 1-1.5 hour；Be exposed to the sun or dry to rice straw water content be 9%-13%；
C. priming leaf: extract rice straw leaf and weeds；
D. section is cut: the rice straw after priming leaf is cut into the segment of 5-20 centimetre；
E. for the first time soaking paste: the straw after section is cut immerses in serosity, after complete soaking paste 10 days, taking-up is dried, then
60 DEG C of constant temperature are dried for 12 hours；Described serosity comprises following component: resin 2 parts, ethanol 4 parts, natural rubber 3 parts, sulfur 0.5
Part, 0.5 part of age resistor；
F: get rid of and cut: the rice straw after drying gets rid of in rejection tablet machine to be cut, and first rotating speed 1000 revs/min, gets rid of and cut 30 minutes；Its
Secondary rotating speed 1500 revs/min, gets rid of and cuts 30 minutes；Last rotating speed 2000 revs/min；Get rid of and cut 30 minutes；
G: soaking paste for the second time: get rid of the rice straw after cutting and immerse in the emulsion being diluted to 25% fine rubber and second the third glue, completely
After soaking paste 13 days, taking-up is dried, 110 DEG C of drying；
H: sulfuration: the rice straw of dipped nitrile rubber and second the third glue is carried out vulcanizing treatment, curing temperature in curing cage
Being 160 DEG C, the time is 4 hours；
I: napping: the rice straw after sulfuration is carried out napping process.
Further technical scheme, in described b step, be exposed to the sun or dry to rice straw water content be 9%-12%.
The making step of the composite fibre of the present invention is simple and easy to do, it is low to consume energy, and it is good that the composite fibre prepared has quality, close
Spend the advantages such as little, intensity is high, high temperature resistant, Heat stability is good, impurity are few, purposes is wide.
