Problems solved by technology

[0012] Among them, the process method of Publication No. CN1415649 still has the following problems: 1) It simply describes a kind of processing idea. As we all know, there are many kinds of organic matter, and there are tens of thousands of them that also play a role in surface modification. Therefore, the patent The actual guiding significance of CN1 415649 is very limited; 2) the problem of hydrophilicity on the surface of the material is not solved, resulting in that the fibers are not easy to disperse into the plastic matrix, and the electromagnetic shielding effect of the finished product is relatively poor

Embodiment 1

[0056] In the first embodiment, the diameter of the stainless steel fiber in the plastic masterbatch containing stainless steel fiber is 12 μm, the length is 6 mm, and the volume ratio of the stainless steel fiber is 25%. The specific production process is:

[0057] 1) A bunch of continuous stainless steel fibers are immersed in a 3% (Wt%) ethanol solution of sodium tridecyl sulfosuccinate for coupling modification treatment to make it have a lipophilic modified surface. On the premise of ensuring that the entire bundle of stainless steel fiber is fluffy and fully infiltrated, try to straighten the stainless steel fiber bundle. Dry the treated stainless steel fiber bundle.

[0058] 2) In step 1), the stainless steel fiber is introduced into a polyoxypropylene polyoxyethylene block type polyether ethanol solution (molecular weight about 2600) with a concentration of 35% (Wt%) for coating, so that the polyoxypropylene polyoxyethylene is embedded The segmented polyether forms a coat...

Embodiment 2

[0067] Compared with the first embodiment, the stainless steel fiber in the stainless steel fiber-containing plastic masterbatch in the second embodiment also has a diameter of 12 μm and a length of 6 mm. The difference is that the stainless steel fiber content in the plastic masterbatch is 30v%. The specific production process is:

[0068] 1) Immerse a bunch of continuous stainless steel fibers in an aqueous solution of 3-aminopropyltriethoxysilane with a concentration of 3% (Wt%) for coupling modification treatment to make it have a lipophilic modified surface. On the premise of ensuring that the entire bundle of stainless steel fiber is fluffy and fully infiltrated, try to straighten the stainless steel fiber bundle.

[0069] 2) The stainless steel fiber is introduced into the methoxy butyl ester solution of the propoxy bisphenol A fumaric acid resin with a concentration of 30% (Wt%) for coating, so that the propoxy bisphenol A fumaric acid resin is in the bundle of stainless st...

Embodiment 3

[0077] In the third embodiment, the stainless steel fiber in the plastic masterbatch containing stainless steel fiber has a diameter of 12 μm and a length of 6 mm, and the volume ratio of the stainless steel fiber is about 92%. The specific production process is:

[0078] 1) Immerse a bunch of continuous stainless steel fibers in a 5% (Wt%) concentration of bis(dioctyloxypyrophosphate) ethylene titanate ethylene propanol solution for coupling modification treatment to make it lipophilic. Sexual surface. On the premise of ensuring that the entire bundle of stainless steel fiber is fluffy and fully infiltrated, try to straighten the stainless steel fiber bundle. Dry the treated stainless steel fiber bundle.

[0079] 2) In step 1), the stainless steel fiber is introduced into the methoxy butyl ester solution with a concentration of 30% (Wt%) propoxy bisphenol A fumaric acid resin to coat, so that the propoxy bisphenol A fumar The acid resin forms a coating layer on the surface of e...

Abstract

The invention discloses a preparation method of a conductive plastics master batch containing stainless steel fibers. The stainless steel fibers in the plastics master batch are isolated by macromolecular materials and completely packed by the macromolecular materials. When the plastics master batch as raw materials is mixed with plastics for secondary granulation or a conductive plastic work-piece is formed, the stainless steel fibers can resist high shear force when the plastics are processed, and are easily and uniformly dispersed in the plastic work-piece and overlap to each other to forma three-dimensional conductive network. By adopting the conductive plastics master batch, the ideal antistatic and electromagnetic screen effects can be achieved under the circumstance of low contentof the stainless steel fiber.

Description

Technical field [0001] The invention belongs to the technical field of organic electronic materials, and specifically relates to a method for manufacturing conductive plastic master batches containing stainless steel fibers. Background technique [0002] Conductive plastic is a new type of anti-static and anti-electromagnetic wave functional plastic. It is a new type of organic electronic material that is successfully developed by high-tech in the market. Conductive plastics are composite materials made of a mixture of conductive media and plastics. The type and uniformity of the conductive media are important factors that affect the performance of conductive plastics. Currently, the commonly used conductive media include conductive powder (such as carbon black, metal powder, etc.) and conductive fiber (such as stainless steel fiber, carbon fiber, nickel-plated carbon fiber, etc.). [0003] The conductive powder contacts each other in the matrix to form a conductive network, so a ...
