Description
【Technical field】
The invention belongs to 3D printing technical field of material, and in particular to a kind of stone wood plastic sectional printed material of producing
New technology.
【Background technology】
3D printing is also called rapid shaping technique, also referred to as increases material manufacturing technology, is that one kind does not need conventional tool, fixture
And lathe, but based on mathematical model file, successively printed using the material with adhesion such as metal dust or plastics
To manufacture the technology of arbitrary shape article.The article that 3D printer can be manufactured is a lot, such as aircraft, pistol, for another example food, human body
Organ, toy for children etc..3D printing technique is an important breakthrough of world's manufacturing technology field over the past two decades.It is mechanic
The multidisciplinary technology such as journey, computer technology, Numeric Control Technology, material science it is integrated.It is to beat that 3D printing is most difficult to most crucial technology
Print the exploitation of material.Therefore developing more various multi-functional 3D printing material turns into focus of the future studies with application and pass
Key.3D printing material of the invention is a kind of new material, has the performance of bamboo wood and plastics concurrently, for 3D printing provides more materials
Selection in terms of material.
Polypropylene has nontoxic, tasteless, and mechanical property is good, and easy processing is corrosion-resistant, and melt temperature is relatively low, and good fluidity is cold
But speed is fast, all meets requirement of the 3D printing technique to polymeric material the advantages of transparent easy dyeing, and pp material is originated
Extensively, price is low；Bamboo fiber/PP composite material causes its double grading for having bamboo wood and plastics concurrently, bamboo fiber plus
Enter reduce further polyacrylic condensation shrinkage factor, and the article for printing has woodiness touch, more friendliness.
Wood plastic composite (WPC), is a kind of main by material based on timber or cellulose and answering that plastics are made
Condensation material, exactly makes a certain proportion of wood-fibred (such as wood powder, powder of straw, cotton stalk powder, bamboo powder, shell powder) by pretreatment
A kind of new material being combined into thermoplastic polymer resin or other materials；The new material not only environmental protection but also tool
There is good mechanical stability, but the two big raw material wood-fibreds and polyolefin that constitute wood plastic composite are all inflammability materials
Material, is that this composite is also combustible material, and it is materials application development to assign the good fire resistance of wood plastic composite
The need for；The individually fire-retardant research to timber and wood-fibred has a lot, typically there is phosphorus-nitrogenated flame retardant；Boron flame retardant；It is halogen
Fire retardant；Other inorganic salts etc.；But it is main based on phosphorus-nitrogenated flame retardant, it is considered to be optimum wood fire retardant, phosphorus,
Two kinds of elements of nitrogen play synergy in wood fire retardant and improve flame retardant effect；But these fire retardants almost have one jointly
The characteristics of, it is exactly the thermal degradation temperature for significantly reducing wood-fibred, this may result in the processing that cannot carry out composite；It is right
Also many in the research of polyolefin flame-retardant, its flame resistant method is frequently with halogen containing flame-retardant and antimony oxide (Sb2O3) coordinate make
With；Metal hydroxides (Al (OH)3、Mg(OH)2) fire retardant；Expansibility flame-proof agent；Ammonium polyphosphate flame retardant etc.；Halogen-free flameproof
The focus of polyolefin flame-retardant research, expanding fire retardant polyolefin/Wood Fiber Composites are carried out it is dual it is fire-retardant be that this is combined
The focus of the fire-retardant research of material；But the addition of fire retardant often deteriorates the mechanical property of composite, therefore to fire-retardant multiple
The research of the research flame-proof composite material of condensation material will simultaneously study interface compatibility, heat endurance and anti-flammability, to be managed
The flame-proof composite material thought.
Wood plastic composite has preferable machinability, beautiful, generous while anticorrosive, however, its defect is in
Not good enough in its mechanical property, therefore, people seek solution route, once someone was re-introduced into stone flour in wood plastic composite, used
In shaping stone wood plastic composite, however, the problems such as due to interface compatibility, the mechanical performance of the composite for finally giving compared with
Difference.
