Abstract
The invention discloses a method for manufacturing a self-plasticizing bamboo board. The method comprises the following steps of (1) material preparation: crashing a bamboo material into bamboo powder with a size of 20-200 meshes, uniformly mixing the bamboo powder and plasticizing initiator according to a mass ratio of m bamboo powder to m plasticizing initiator being equal to 100 to 0.1 to 100 to 0.4, obtaining a bamboo powder raw material; (2) self-plasticizing molding: uniformly placing the bamboo powder raw material in a stainless steel die, and then rising the temperature and increasing the pressure, when the temperature rises at 160 to 200 DEG C, and when the pressure is increased at 9 to 21 MPa, keeping the pressure and temperature for 10 to 90 min, and then keeping the pressure, stopping heating, slowly cooling to a room temperature, relieving the pressure, obtaining the self-plasticizing bamboo board. The method provided by the invention can be easily realized, the operation is convenient, the production cost is low, thus, the method is suitable for being used for large-scale production; and moreover, the processing and utilization routes of the bamboo material are widened, and larger utilization of bamboo material resources is realized simultaneously.
Description
Technical field
The present invention relates to a kind of manufacture method from plasticizing bamboo clappers, specifically, relate to a kind of method of bamboo wood manufacture from plasticizing bamboo clappers of utilizing.
Background technology
Bamboo wood is one of world-renowned fast growing plant, is also one of fast-growing Silvicultural of subtropical and tropical zones first-selection.At present, bamboo wood is mainly distributed in the ground such as Asia, America, Africa, and particularly the state such as China, India, Japan, Burma plants bamboo wood artificial forest in a large number, and area reaches 2,000 ten thousand hectares, produces 18000000 tons of bamboo woods per year.China's bamboo grove area exceedes the county (city) of 10,000 hectares more than 130, and the gross area reaches 7,000,000 hectares.Bamboo wood artificial forest becomes a useful person, and the cycle is short, output is high, form is perfectly straight, and material is closely knit, and fiber is elongated, and major product has glued board, floor, particieboard, fiberboard, summer sleeping mat, pulping and paper-making, handicraft etc., and annual value of production reaches tens billion of units.But, bamboo wood exists the defects such as physical and mechanical property anisotropy is large, hollow structure, cause bamboo processing utilization efficiency low and produce the serious wasting of resources, and it is rotten easily to go mouldy in processing, storage, transport, in using, and is difficult to apply on high-end product.If bamboo wood is after plastics processing, can be widely used in the high value added product fields such as packaging for foodstuff, field engineering, Landscape furniture, also can be made into the component of machine of the products such as aircraft, automobile, boats and ships, is to solve the wasting of resources and the low key of benefit in bamboo processing.
Plasticizing refers to that plastics reach flow regime and have good plastic overall process through heating in barrel at first, along with plastifying technology is applied, increasing raw material (comprising biological material) all can carry out plastics processing, to improve raw material availability and processing characteristics, reach resource maximum using.Nineteen forty-seven, a kind of method that plastifies ripple record has been delivered in Haley research, subsequently, 0ngil Gonzalez should be used as in human pathology and association area thereof plastifying material and having discussed and prospect, Milch has found carbohydrate collagen plasticizing function, due to the fast development of plastics industry at that time, adds plastic components single, research and preparation difficulty are relatively little, make carbohydrate plasticizing research by stranded; Along with petroleum resources growing tension, in recent years, the plasticizing research of biological material has become study hotspot.
In timber (bamboo wood) plasticizing manufacture field, mainly contain two kinds of technology paths: the one, resin is immersed in timber or bamboo wood, rely on the plastics of resin and impel timber or bamboo wood plasticizing, the voidage of timber is high, resin is easy to immerse, and plasticizing effect is good, and the densification of bamboo wood quality, resin is difficult to immerse, and causes bamboo wood plasticizing effect not good; The 2nd, plastics are evenly mixed with timber (bamboo wood), by technological formings such as extrusion molding, mold pressing, injections, be wood and plastic composite or bamboo-plastic combined material, and the bamboo-plastic combined material of developing is because of the poor industrialized utilization that is difficult to of interface amalgamation, simultaneously, plastics addition is at least 30%, price is 2～5 times of wooden bamboo raw materials, cause cost significantly to increase, and value of the product synergy is not obvious.In order to solve bamboo wood plasticizing effect and plasticizing cost simultaneously, carrying out bamboo culm wall is the key that realizes bamboo wood plasticizing secondary industry from the research of plasticizing.Under the support of the departments such as state natural sciences fund committee, Science and Technology Department of Hunan Province, the present patent application people has carried out scientific research and the research of technique of system to certainly plastifying bamboo clappers, find that under high pressure bamboo wood has the characteristic from plasticizing, and invent this technology, this technique is easy to realization, easy to operate, realize the maximum using of bamboo timber resource, provide technical support for increasing bamboo people income.
Summary of the invention
Technical problem to be solved by this invention is to provide and is a kind ofly easy to realize, the manufacture method that certainly plastifies bamboo clappers that easy to operate, production cost is low.
In order to solve the problems of the technologies described above, a kind of manufacture method from plasticizing bamboo clappers that the present invention adopts, is made up of following steps:
(1) get the raw materials ready: bamboo wood is ground into 20 order～200 object bamboo powder, m in mass ratio
bamboo powder: m
plasticizing initator=100: 0.1～100: 0.4, bamboo powder is evenly mixed with plasticizing initator, obtain bamboo powder raw material; Wherein bamboo powder moisture content is 20%～50%; Plasticizing initator is by polyvinyl alcohol, polyethylene glycol m in mass ratio
polyvinyl alcohol: m
polyethylene glycol=0.3: 10～1: 10 mix;
(2) from plasticizing forming: bamboo powder raw material uniform spreading installs in stainless steel mould, then start to heat up, boost, in the time that temperature rises to 160 DEG C～200 DEG C, pressure and rises to 9MPa～21MPa, pressure-maintaining and heat-preservation 10 minutes～90 minutes, then keep pressure, stop heating, slowly cool to room temperature, removal pressure, obtains from plasticizing bamboo clappers; In wherein mating formation, the bamboo powder raw material face of mating formation can not exceed apart from the horizontal plane of 1 centimetre suitable for reading of stainless steel mould; Be 12 hours～16 hours cool time; Stainless steel mould is prepared according to Product Design.
Adopt the manufacture method that certainly plastifies bamboo clappers of technique scheme, be easy to realize, easy to operate, production cost is low, is applicable to large-scale production, and product has physicochemical property and the processing characteristics of rigid plastics, widen bamboo processing utilization approach, realize the utilization of largeizationr of bamboo timber resource economy simultaneously, can increase self-employed tree cultivator's income, significant to building a harmonious society.This invention can produce significant economic and social profit, has good promotional value.
