Description
Technical field
The present invention relates to composite bamboo preparing technical field, more particularly to a kind of fretting map bamboo powder-rubber composite
Preparation method.
Background technology
Bamboo-plastic composite material is to be added in the form of bamboo fibre, bamboo powder for reinforcing material or filler in thermoplastic,
And the thermoplastic of bamboo wood and molten condition is combined by heating, or refer to the micro- of organic monomer injection bamboo wood
In fine texture, then handled using radiation method or membrane by accelerant process etc., organic monomer is produced graft copolymerization or homopolymerization with bamboo wood component
A kind of material of thing.But because bamboo powder or bamboo fibre surface have substantial amounts of polar hydroxyl groups, its phase with high-molecular compound
Capacitive is very poor, and it is poor to directly result in obtained composite performance, it is impossible to meets needed for actual production life.
Chinese patent CN103396675 discloses a kind of place of the raw material for injection grade fine foaming wood plastic composite materials
Reason method, be by bamboo and wood give up powder at 160-280 DEG C after microwave drying treatment again through nano calcium oxide adsorption treatment, improve its with
The compatibility of resin matrix.《Colloid and polymer》" the bamboo powder modified rubber composite wood that in September, 2016 the 3rd periodical of volume 34 is stepped on
The text of the preparation of material and performance study " one by by bamboo powder after KH-580 surface modification treatments the mixing and molding together with rubber, carry
The high tensile strength and elongation at break of elastomeric material.It can be seen that the above-mentioned processing method to bamboo powder achieves certain effect
Fruit, but heat treatment destroys the natural texture of bamboo powder, competitiveness of product in market deficiency.
The content of the invention
A kind of the defects of present invention is in order to make up prior art, there is provided preparation side of fretting map bamboo powder-rubber composite
Method.
The present invention is achieved by the following technical solutions：
A kind of preparation method of fretting map bamboo powder-rubber composite, comprises the following steps：
（1）By bamboo wood, to be ground into 50-200 mesh bamboo powders standby after dehydrating processing；
（2）Filtered after being stirred 35-60min in the bamboo powder input organic silicon sol for crushing dispensing, resulting material is in nitrogen
25-50min is handled with 65-70 DEG C of heated-air drying under atmosphere, the bamboo powder for obtaining Ludox cladding is standby；
（3）Epoxy natural rubber, room temperature vulcanized silicone rubber are put into banbury, at a temperature of 15-80 DEG C, with 65-85rpm
Rotor speed under be kneaded 12-16min, then add Ludox cladding bamboo powder, auxiliary agent, foaming agent, continue be kneaded 20-
Elastomeric compound is obtained after 30min；
（4）Discharged after elastomeric compound is vulcanized into 5-15min at 50-100 DEG C, produce described micro foaming composite material.
Described organic silicon sol is to be prepared by the following method：The commercially available Ludox that solid content is 20-30% is taken,
Silane coupler is added dropwise under stirring condition, continues stirring reaction 15-24h after being added dropwise, then adds tetrahydrofuran, mixing is equal
System is removed into moisture by depressurizing rotary evaporation after even, produces described organic silicon sol.
Described Ludox, silane coupler and the volume ratio of tetrahydrofuran three is 1:0.1-0.15:1-1.5.
The epoxidation level of described epoxy natural rubber is 20-50%.
Described auxiliary agent is by 1-5% chitosan hydrochlorides, 20-30% stearic acid, 20-40% accelerator Ms and surplus
Sulphur composition.
Described epoxy natural rubber, room temperature vulcanized silicone rubber, Ludox cladding bamboo powder, auxiliary agent, the weight of foaming agent
Proportioning is as follows：Epoxy natural rubber 20-30, room temperature vulcanized silicone rubber 50-60, Ludox cladding bamboo powder 50-80, auxiliary agent 3-8,
Foaming agent 3-6.
The present invention handles the bamboo powder after the processing of Ludox cladding with composite rubber material through cryogenic vulcanization foaming, is made
A kind of combination property good compounded rubber expanded material, realizes effective combination of bamboo powder and elastomeric material, realizes bamboo
The high level application of resource, reduces production cost.The Ludox used in the present invention is organic after silane coupler modified
Ludox, be a kind of non-aqueous dicyandiamide solution, avoid in the bamboo powder after moisture is introduced into drying process, the bamboo powder after cladding compared with
Solvent can be removed at low temperature, has been maximally maintained the nature of bamboo powder, modified bamboo powder and rubbery system
With excellent compatibility and associativity, so as to effectively improve the mechanical property of rubber expanded material, reduce and be produced into
This.
