Abstract
The invention relates to a bamboo powder - high-density polyethylene composite and its process for preparing, which consists of granulating in the twin-screw extruder after kneading the raw material components comprising bamboo powder, high-density polyvinyl resin, polyethylene oxide and geoceric acid, then obtaining the product by squeezing the master batch in the single screw extractor. The external appearance of the invented bamboo powder - high-density polyethylene composite is close to the wood, and the invented product has good fire-retardancy. By changing different dies, complex-shaped products can be prepared and is capable of boring, digging and nailing. The product of this invention is of no release of formaldehyde, of nice appearance, good handle, no warp, excellent resistance to aging, and so it has a prodigious superiority outside, for example, it can be used as marine landscape materials such as corridor, sunshade, baluster and movable dwelling.
Description
Technical field
The present invention relates to a kind of high-density polyethylene composite material, relate to a kind of bamboo powder-high density polyethylene composite materials and preparation method thereof specifically.
Background technology
It is compound to utilize plant powder and Plastic Resin to carry out blend, is the new model of the high value comprehensive utilization of plant resources.The advantage of plastics and vegetable fibre is organically combined, make the material that obtains to carry out surface gummed, paint as timber, and bore, dig, nail etc., can process as the thermoplastics extrusion moulding again, given full play to the workability of vegetable material and processing of plastic method diversity, handiness, Application Areas is very extensive.
Bamboo is a kind of important renewable plant, has the regeneration of being easy to, and output is big, to advantages such as environment and ecological damage are few.Bamboo and macromolecule resin carry out compoundly can obtaining bamboo-plastic composite material.Present focus mostly on compound in bamboo fiber/polypropylene of the matrix material of bamboo and plastics.Document [Li Zhenghong, the research of bamboo fibers reinforced polypropylene compound material, Fujian Forestry Inst.'s journal, 2005,25 (3): 179-201] has provided a kind of method for preparing the bamboo fibers reinforced polypropylene compound material.Document [Chen Zhe, Liu Detao, Zhao Renjie, waste or used plastics and bamboo industrial wood waste are made the experimental study of bamboo-plastic combined plate, the wood-based plate communication, 2004,11 (8): 11-13,15] provided utilize waste polypropylene plastic particle and bamboo surplus material of processing bamboo fibers for raw material by the compound method for preparing composite sheet of concora crush.Yet the length-to-diameter ratio of bamboo fibers is too big, and material fluidity is poor in the time of compound, and working method is limited, can only process with compression molding, can not carry out the widely used processing of extruding, and compound back apparent property is relatively poor, has therefore limited the application of goods.
Summary of the invention
The objective of the invention is to develop a kind of advantage that has vegetable material and plastics concurrently, handling ease, and the good matrix material of apparent property, another purpose provides the preparation method of this matrix material.
The present invention passes through the bamboo powder, high-density polyethylene resin, oxidic polyethylene and stearic acid are mediated the back and carry out granulation in twin screw extruders, then master batch is extruded in single screw extrusion machine, the matrix material outward appearance that obtains is near timber, good hand touch, and have the advantage of timber and plastics concurrently, thus realized purpose of the present invention.
Bamboo powder-high density polyethylene composite materials of the present invention, its composition of raw materials according to the mass fraction, by 20～80 parts in bamboo powder, 20～80 parts of high-density polyethylene resins, 1～5 part of oxidic polyethylene and 0.5～10 part of composition of stearic acid.
The preparation method of bamboo powder-high density polyethylene composite materials of the present invention comprises the steps:
(1) press formula rate with the bamboo powder, high-density polyethylene resin, oxidic polyethylene and stearic acid are mediated;
(2) raw material after step (1) kneading is carried out granulation in twin screw extruder, obtain master batch;
(3) master batch that step (2) is obtained is extruded in single screw extrusion machine, obtains matrix material.
The particle diameter of the described bamboo powder of step (1) is 0.147mm～0.833mm preferably, the moisture content of bamboo powder preferably can obtain by bamboo is pulverized to spread then to dry or dry less than massfraction 10% described bamboo powder, described high density polyethylene(HDPE), chlorinatedpolyethylene and stearic acid all can be bought from the market, the kneading temperature is a room temperature, 2～30 minutes kneading time.
The present invention is owing to adopt high density polyethylene(HDPE) as matrix resin, and outward appearance is near timber, and the goods added value is big, and adopt the bamboo powder as raw material, utilize extrusion molding processing, by changing different moulds, can prepare complex-shaped goods, and can bore, dig, follow closely.The formaldehydeless release of the goods that obtain, outward appearance is good, good hand touch, ageing-resistant excellence, warpage not, outdoor, seashore view material such as path, sunshade, railing, using on the movable dwellings has very big advantage.
