Description

A kind of rapid shaping raw material based on rubber elastomer
Technical field
The present invention relates to elastomeric material manufacture field, and in particular to a kind of rapid shaping raw material based on rubber elastomer.
Background technology
3 D Printer is the early 1990s later 1980s rise and develop rapidly new Advanced manufacturing technology, based on it is a kind of mathematical model file, with powdery metal or plastics etc. can jointing material, pass through The mode successively printed carrys out the technology of constructed object.It is the skill of CAD, Numeric Control Technology, laser technology and Materials Science and Engineering Art is integrated.Design philosophy automatically and quickly can be turned materially the prototype with certain 26S Proteasome Structure and Function or directly manufacture zero by it Part, so as to carry out Fast Evaluation, modification to product design, to respond the market demand, improves the competitiveness of enterprise.3D is beaten Print technology is widely used in automobile, household electrical appliances, electric tool, medical treatment, machining, hot investment casting, Aero-Space, handicraft manufacture And the industry such as toy for children.The main advantage of 3D printing includes：1st, complex article is manufactured；2nd, product diversification is not added to This；3rd, it is with short production cycle；4th, zero technical ability is manufactured；5th, do not take up space, portable manufacture；6th, material is saved.
3D printing technique will be applied in rubber, then rubber will adapt to 3D and beat in structure with the raw material that use The requirement of print technology.Rubber largely uses single mixing material, in order to obtain necessary physical and mechanical properties, physics Chemical property, has used various compounding ingredients and filler, while also needing by sulfuration process, this original required 3D printing technique For material, as long as sulfuration process is incorporated material modified used in 3D printing technique can be achieved on.Current 3D printing Successful print goes out the rubbers such as ball boots to technology.Therefore, in theory, 3D printing technique can apply to many types Rubber, still, using 3D technology large-scale production rubber also have very big distance：One is that production cost is too high；Two It is that speed of production is too low；Three be the rubber produced hardly consistent with use requirement.However, being used as high-end rubber Single-piece production be feasible and promising.
The content of the invention
In order to solve the above problems, the invention discloses a kind of use condition is simple, environmental pollution is small, good product performance, Precision height, good fluidity, the rapid shaping raw material based on rubber elastomer of high mechanical strength.
To realize the purpose of the present invention, the present invention is adopted the following technical scheme that：

Specifically, described rubber powder is in butadiene-styrene rubber, butadiene rubber, EP rubbers, nitrile rubber, neoprene One kind.
Specifically, the particle mean size of described rubber powder is 80-200 mesh.
Specifically, described age resistor N- phenyl-2-naphthylamines, N, N '-two (betanaphthyl) p-phenylenediamine, N- isopropyls-N '- One or more in diphenyl-para-phenylene diamine.
Specifically, described vulcanizing agent is one kind in 2- benzothiazolyl mercaptans, dibenzothiazyl disulfide.
Specifically, described reinforcing agent is nanometer silicon carbide whiskers and polyimide fiber using weight ratio as (2-5): 1 mixes Conjunction is formed, a diameter of 10-100nm.
Specifically, described surfactant be tributyl phosphate, sodium lignin sulfonate, Sodium Polyacrylate in one kind or It is several.
Specifically, described fire retardant is triphenyl phosphate, tricresyl phosphate benzene methyl, one kind in deca-BDE or several Kind.
Specifically, described plasticizer is coumarone indene resin.
Specifically, described inorganic filler is the one or more in silica, calcium carbonate, clay.
The device have the advantages that：
(1) the rapid shaping raw material use condition based on rubber elastomer of the invention provided is simple, environmental pollution is small, production The good, precision of moral character energy is high.
(2) plasticizer and surfactant that the present invention is selected have preferable synergy so that rubber elastomer Rapid shaping material flow is good, reinforcing agent can assign moulded products higher mechanical strength.
(3) raw material of the present invention obtains in extensive range, and preparation method is simple and easy to apply, and cost is low, is conducive to the popularization of the marketization And application.
