Description
Technical field
The present invention relates to chemical material technical field, especially a kind of anti-ageing wood-plastic composite and preparation method thereof.
Background technology
The reserves of Nonrenewable resources existing on the earth are very limited, and along with the fast development of plastics industry, " white pollution " that caused by plastics brings great harm to the production of the mankind and living environment.In order to solve, there is lack of raw materials and environmental problem, and people transfer to eye on tellurian renewable resources gradually.Sponge is a kind of natural macromolecular material, is a kind of inexhaustible, nexhaustible resource.The potential advantages that vegetable fibre is used for matrix material more and more attract much attention, and it is cheap, and density is little, has higher Young's modulus, close with inorganic fibre, and its biological degradability and recyclability are the most outstanding advantages.
Wood plastic composite vegetable fibre and plastics is carried out the class matrix material that blending extrusion obtains, wood plastic composite have close higher than performance, cheap, can solve because waste or used plastics cannot reclaim problem to environment, and the wood plastic composite of the advantage such as fiber waste resource is fully used.Current wood plastic composite has been applied to the fields such as floor, wallboard, building template.The wood plastic composite of China's research mainly utilizes xylon and thermosetting resin to carry out blended matrix material, but along with urbanization and industrialized development, the forest reserves of the mankind are fewer and feweri, timber resources is more and more precious, in order to adapt to the requirement of environmental protection, occur that some utilize waste fiber such as the waste fibers such as stalk, straw, corn stalk to prepare wood plastic composite in the last few years.Due to thermoplastics and vegetable fibre poor compatibility, interfacial interaction power is weak, thus cause that its mechanical strength is relatively low, wear resisting property is low, but it is obviously not enough also to there are some, current wood plastic composite is as life-time service, particularly outdoor use, the catabiosis such as easily ftracture, fade, thus shorten its work-ing life, define its use range.
Bamboo fibers is exactly a kind of cellulosic fibre extracted from the bamboo of self-sow, is the fifth-largest natural fiber after cotton, fiber crops, hair, silk.The Component units of bamboo fibre products, can be individual fibers cell or fibrous bundle.Bamboo fibers have good ventilation property, moment the characteristic such as water-absorbent, stronger wear resistance and good dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function.Bamboo fibers is a kind of natural environmental-protective type green fiber truly.Be mainly used at present in textile industry, seldom have the research report being applied to and preparing wood plastic composite.
Summary of the invention
The problems referred to above will be there are in the present invention for current wood plastic composite, there is provided a kind of with bamboo powder and waste plastic for main raw material prepares a kind of wood plastic composite, this wood plastic composite, except having the features such as Traditional Wood plastic composite materials is recyclable, renewable, also has the features such as mechanical property is high, wear-resisting, ageing-resistant, colour-fast, without putrefaction.
In order to realize above object, the present invention is achieved through the following technical solutions:
A kind of anti-ageing wood-plastic composite, comprises the raw material of following parts by weight:
Bamboo powder 60-90 part, waste plastic 40-50 part, polypropylene 15-25 part, calcium carbonate crystal whisker 8-12 part, nano-calcium carbonate 3-5 part, pentalyn 2-4 part, nano zine oxide antiseptic-germicide 2-4 part, 3-5 part antioxidant 1070,2-3 part photostabilizer 622 and waterproofing agent of organosilicon 2-3 part.
The above a kind of anti-ageing wood-plastic composite, the particle diameter of described bamboo powder is 100-150 order.
A preparation method for anti-ageing wood-plastic composite, comprises the following steps:
(1) modification pre-treatment: 60-90 part bamboo powder, 3-5 part nano-calcium carbonate and 2-4 part pentalyn are added ball mill, stirs 12-15min under rotating speed is 100-150r/min, obtains modified fibre;
(2) high speed batch mixing: above-mentioned modified fibre and each component raw material of residue are added high-speed mixer, are 200-300 at rotating speed
Stir 8-12min under r/min, obtain mixture;
(3) hot-forming: mixture is added thermo-pressing moulder, temperature be 190-210 DEG C, pressure be 11-13Mpa under thermocompression forming 80-100S, shaping wood plastic composite can be obtained;
(4) cooling and shaping: shaping wood plastic composite naturally cools to room temperature, can obtain wood plastic composite.
Compared with prior art, advantage of the present invention and positively effect are:
(1) the present invention is using bamboo fibers as main raw material, raw material sources are extensive, cheap, fully utilize solid waste, achieve the Sustainable development of resource, bamboo fibers has the characteristics such as good ventilation property, water-absorbent, stronger wear resistance and good dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function, thus make wood plastic composite have better germ resistance, water-absorbent, wear resistance, be not easy to occur catabiosis such as fading.
(2) use waste plastic and polypropylene both can reduce costs as main raw material, the problem that waste plastic cohesiveness is low and polyethylene cost is high can be overcome simultaneously, solve again " white pollution " problem that waste plastic brings.
(3) plus nano calcium carbonate and pentalyn are as properties-correcting agent, improve the consistency of fiber and plastics, cross section interaction force is strengthened, improve the mechanical property of wood plastic composite, nano-calcium carbonate can not only strengthen the consistency of vegetable fibre and plastics, effectively can also improve firm, toughness, smooth finish and the flexural strength of product; Improve processing characteristics, improve ratio of briquetting; Improve product rheology energy, stability, heat-resistant stability, wear resistance, there is filling and strengthen, toughness reinforcing effect.
(4) add antiseptic-germicide, antioxidant, photostabilizer and waterproofing agent of organosilicon, make wood plastic composite have good ageing-resistant performance, antioxidant property, stability and water-repellancy, thus extend work-ing life.
(5) the present invention also has that complete processing is simple, process period is short, low cost and other advantages, is applicable to suitability for industrialized production.
