Abstract

The invention discloses a method for the preparation of solvent-free synthetic leather by 3D printing, comprising the steps of: (1) the designed pattern is printed for a stereomodel of the pattern by a 3D printer, (2) the silica gel is uniformly coated on the stereomodel, solidified and stripped to obtain the silica gel plate with reverse pattern, (3) materials A and B of the polyurea slurry are taken to be delivered respectively to the spray gun of the spraying equipment with the spraying equipment, mixed and sprayed quickly and evenly onto the silica gel plate to form a slurry layer which completely covers the pattern. After the spraying, the base fabric is bonded to the slurry layer immediately. After the solidifying, it is separated from the silica gel plate to obtain the synthetic leather with the designed pattern on the surface. So synthetic leather has the advantages of high pattern simulation effect, leaving no solvent residue, rapid prototyping and superior physical properties, and has positive effect in pollution reduction and ecological protection.

Description

A kind of 3d prints the solvent-free method preparing synthetic leather
Technical field
The present invention relates to a kind of 3d prints the solvent-free method preparing synthetic leather.
Background technology
Conventional dry method veneer is prepared synthetic leather technology and is limited by the organic solvents such as dmf, mek, the body to environment and workman Heart health works the mischief.In addition, have the synthetic leather market of various lines, pattern demand very big, but existing technology produce Synthetic leather, its surface pattern, the fidelity of pattern and third dimension are all barely satisfactory.It is therefore desirable to invention one kind prepares surface There is the new method of the synthetic leather of lines, pattern.
In order to realize foregoing invention purpose, 3d provided by the present invention print the solvent-free method preparing synthetic leather include with Lower step:
(1) modelling of lines
The pattern designing lines is printed the stereomodel of lines by 3d printer;
(2) transfer silica gel plate
Silica gel is uniformly coated on stereomodel, peels off after solidification, prepared silica gel plate;
(3) slurry spraying is fitted with base fabric
Take a of polyureas slurry to expect and b material, sprayed after the spray gun mixing with spraying equipment, a material and b material being delivered to respectively spraying equipment Rifle rapidly and uniformly sprays on silica gel plate, forms the pulp layer that lines is completely covered, is fitted in base fabric immediately after having sprayed On pulp layer, peel off with silica gel plate after solidification, surface is just obtained there is the synthetic leather setting pattern lines.
The main component of described a material is isocyanates, and the main component of b material is amino-compound;Described a material and b material exist The weight of the quantity for spray in the unit interval is than for 100:35-85.
3d print a kind of based on mathematical model file, with powdery metal or plastics etc. can jointing material, pass through The mode successively printing carrys out the technology of constructed object, is often used for modeling in fields such as Making mold, industrial designs, after by Gradually it is used for the direct manufacture of some products, there is now the parts product printing using this technology.3d printing technique, energy Enough vivid represent lines effect, by target lines portray life-like, it is possible to resolve conventional dry makes face product lines Unnatural, the problems such as big lines cannot be realized, the 3d printed material that the present invention selects is photosensitive resin, its model k-3821n.
In step (2) of the present invention, used silica gel is market products, can be limited using Dongguan City good exhibition organosilicon science and technology The silica gel of model 151207a01 that company produces, silica gel is made up of a component and b component, and a group is divided into the poly- first of high molecular Base vinylsiloxane;B group is divided into vulcanizing agent, and its main component is organosilicon oxide;This product physical property preferably, is reacted Molding time is moderate, can fast setting, have enough operating times again.The making of silica gel plate is mainly polysiloxanes and becomes elasticity The process of body,, according to certain ratio mix homogeneously, a component and b component are typically mixed by the weight ratio of 10:1 for the two, mix After closing uniformly, it is coated on the stereomodel of lines, solidifies under uniform temperature, typically using solid at a temperature of 110-170 DEG C Change, peel off after the completion of solidification, obtain transferring the silica gel plate of lines.
Select the solvent-free slurry of polyureas to be existing product in step (3) of the present invention, produced by Xu Chuan Chemical Co., Ltd., by A material and b material composition;For example can be selected for a material of model xcns-6007a and the b material of model xcns-6007b;It is main that a expects Composition is isocyanates, and isocyanates can be aromatic or aliphatic;B expects main component amino-compound, It is made up of Amino End Group resin and Amino End Group chain extender, in Amino End Group resin, do not contain any hydroxyl moieties and catalyst.Isocyanide Acid esters component and amino-compound component react generation polyureas, are a kind of elastomer substances, have superior physical property, pliable and tough Property good, intensity is high, anticorrosive, ageing-resistant, outdoor using up to more than 10 years, increase the service life of product.Polyureas is solvent-free Slurry do not contain catalyst, can fast setting, can not produce sagging phenomenon, 8- in arbitrary surface, inclined-plane and vertical spray mo(u)lding 12 seconds gels, can reach peel strength in 1 minute.Between 100:35-85, reaction temperature is 20- to the mixed proportion of the two 80℃.Because gelation rate is fast, therefore want fast spraying base fabric of quickly fitting, spray and laminating base fabric typically will be in the 8-12 second Complete in clock.If there being color and luster requirement can add mill base in a material, the weight ratio of a material, b material and mill base is for 100:35-85:2;Color Slurry produces hp series special-used colour starch from Fujian Chemical Co., Ltd. of HuaPu, for example, can adopt model hp-5888 and hp-7001 Mill base, its composition is main consistent with a material component, is isocyanate prepolymer composition, does not affect the reaction that a expects that component and b expect after interpolation. Spraying equipment is produced by Zhejiang flying dragon equipment company limited, can accurately regulating flow proportioning and temperature, it mainly has a charging basket, b Charging basket, main frame and spray gun composition, expect a, a charging basket poured respectively into by b material, after b charging basket, start that a expected by main frame, b material passes through two Pipeline is delivered to spray gun respectively and can be sprayed in mixing.
In step (3) of the present invention, base fabric used can be selected for non-weaving cloth, woven fabric, looped fabric or Compound Fabric.
Base fabric can need to design different postfinishing process according to client so that the base fabric made have waterproof, Softness, antibacterial, the different-effect such as fire-retardant.Laminating base fabric, gently can press through pressure roller, 2min is peelable.
In sum, the synthetic leather that the present invention produces has high emulation lines effect, no solvent residue, rapid shaping, thing The advantages of reason superior performance, in terms of reducing pollution, ecological protection, there is good effect.
