Abstract
An expendable and degradable sanitary chopstick is prepared from plant fibres (rich husk, bagasse, or peanut shell) (50-80 wt.%), A5 aminoplastics (3-18), starch (10-25) and polyamide thermosol (2-5) through crushing into 60 meshes powder, uniformly mixing, and then hot die-pressing. Its advantages include smooth surface, high toughness, high resistance to water and high temp., and natural degradation.
Description
The present invention relates to a kind of with the prescription of preparing degradable disposable chopsticks from plant fibres and the invention of technology.
In recent years along with the raising of people's living standard, busy and the personnel that travel outdoors of work increase, the exhibition of breaking out is also met in fast food and catering industry thereupon, in order to ward off disease by the cross infection of people oral cavity, thus a large amount of disposable sanitary chopsticks made from timber and bamboo that uses; Produce these disposable hygienic chopsticks and need expend a large amount of high-quality bamboo wood resources, according to data in the industry show China's every day employed disposable sanitary chopsticks quantity up to number with ten million pair, can only calculate by 40,000 pairs of hygienic chopsticks of processing by every cubic metre, need the large-area bamboo wood of felling forest land, can cause serious soil erosion and desertification and cut down bamboo wood in a large number, and producing a series of ecological environment problem, China formally forbids cutting down natural forest at present.Domesticly in addition brought into use some degradable surrogate substituting disposable foam plastic tablewares, but still do not had the degradable hygienic chopsticks product of a kind of desirable generation disposable bamboo-wood hygienic chopsticks so far in order to cooperate the white pollution of improvement because of adopting the porous plastics tableware to cause.
The purpose of this invention is to provide a kind of prescription and technology with preparing degradable disposable chopsticks from plant fibres.
The prescription of disposable degradable hygienic chopsticks of the present invention and the feature of weight ratio are as follows:
Vegetable fibre powder: 50～80%
The amino film plastics of A5: 3～18%
Starch: 10～25%
Polyamide hot: 2～5%
Adopt the processing step of above-mentioned raw materials prescription manufacturing disposable sanitary chopsticks of the present invention as follows:
1, get the raw materials ready: above-mentioned various raw materials are put into pulverizer, and separated pulverizing is to the powder below fineness 60 orders, by stirring after above-mentioned each raw material weight proportioning mixing;
2, compression molding: with the preheating of hygienic chopsticks compacting tool set elder generation as for 130～180 ℃ and to configure pressing pressure be 20～60kg/cm
2, add the raw material powder for preparing through melting process again and suppress, the dwell time was no less than for 5 seconds during compacting, again ftercompction once and pressurize after 2 seconds release get final product.
The advantage that the vegetable fibre disposable degradable hygienic chopsticks that utilize composition of raw materials of the present invention and production technique to produce are had is that raw material sources are wide, production unit and technology are simple, the hygienic chopsticks smooth surface is straight, good looking appearance, good toughness, water-fast heat-resisting, color and luster nature and also be easy to natural degradation, can not pollute physical environment; And the cost of the hygienic chopsticks of being produced is lower than bamboo wood hygienic chopsticks, is the ideal surrogate of bamboo wood hygienic chopsticks, and the natural forest tree resource and the ecological environmental protection of China had very big important meaning and effect.
Of the present inventionly be performed such ground with the prescription of preparing degradable disposable chopsticks from plant fibres and the most preferred embodiment of technology:
It at first is procedure for preparation, select earlier plant materials such as rice hulls, bagasse, sawdust or Pericarppium arachidis hypogaeae as the fineness below raw material pulverizing to 60 order of desiring to produce the vegetable fibre powder, and with the amino film plastics of A5, starch and the polyamide hot also fineness below separated pulverizing to 60 order; The polyamide hot of the starch of the amino film plastics of the A5 of the vegetable fibre powder of 75% weight ratio, 12% weight ratio, 10% weight ratio and 3% weight ratio being put into stirrer, to mix to each raw material thorough mixing even again.
Carry out the compression molding operation then, counterdie and patrix should be preheated to temperature before the mold pressing is 140 ℃, at this moment can put into counterdie to the compound for preparing through procedure for preparation and stir and suppress, and the pressure-controlling of moulding press is at 40kg/cm
2, the time also answered pressurize 5 seconds in compacting, after the release again ftercompction once, pressing mold is opened in and pressurize 2 seconds again, can obtain disposable degradable hygienic chopsticks finished product.
Claims (2)
1, a kind of is the disposable degradable hygienic chopsticks of raw material with the vegetable fibre, it is characterized in that composition and weight ratio that it comprises are as follows:
Vegetable fibre powder 50～80%;
The amino film plastics 3～18% of A5;
Starch 10～25%;
Polyamide hot 2～5%.
2, a kind of production technique of utilizing described composition of raw materials of claim 1 and weight ratio to produce the disposable degradable hygienic chopsticks is characterized in that this processing step is as follows:
2.1 get the raw materials ready: above-mentioned various raw materials are put into pulverizer, and separated pulverizing is to the powder below fineness 60 orders, by stirring after above-mentioned each raw material weight proportioning mixing;
2.2 compression molding: with the preheating of hygienic chopsticks compacting tool set elder generation as for 130～180 ℃ and to configure pressing pressure be 20～60kg/cm
2, add the raw material powder for preparing through melting process again and suppress, the dwell time was no less than for 5 seconds during compacting, again ftercompction once and pressurize after 2 seconds release get final product.
