CN1805075A - Magnetized plastic material and its processing method - Google Patents

Abstract

The invention relates to a magnetized plastic and relative producing method. Wherein, the magnetized plastic is formed by magnetic powder and PA resin, while the magnetic powder takes 50-70% of total weight; the content of PA resin is 30-50%. The invention is one kind of plastic particle, which can be made into variable shapes via injection molding, comprising the product with complex shape, to be filled with magnet, to attain the magnetic field which can process magnet therapy.

Description

A kind of magnetized plastic and processing method thereof

Technical field

The present invention relates to a kind of magnetized plastic and processing method thereof.

Background technology

As everyone knows, by acupuncture point specific on the human body is carried out the magnetic stimulation of certain intensity regularly, can reach the effect that restores menstrual flow and invigorates blood circulation, dispels the disease diseases prevention, promotes longevity.Therefore various for a certain period magnetic therapy, magnetic health product emerge in an endless stream, and be as magnetization comb, magneto therapeutic glasses, magnetizing health footwear or the like, numerous.At present these products all are to embed permanent magnet blocks on corresponding position usually, and such mode is when running into complex-shaped or requiring magnetic field range more greatly or powerless.

Summary of the invention

The objective of the invention is to provides a kind of Magnetized Material for overcoming the deficiencies in the prior art, and this Magnetized Material is fit to make complex-shaped and requires the bigger Magnetotherapeutic health product of magnetic field range.

Another object of the present invention provides a kind of preparation method of above-mentioned magnetized plastic

For achieving the above object, the invention provides a kind of magnetized plastic, magnetized plastic mainly is made up of magnetic and PA resin, wherein particle content is 50%～70% of a gross mass, the PA resin content is 30%～50% of a gross mass, for products such as picture magnetization comb, magneto therapeutic glasses, preferably particle content is 60% of a gross mass, and the PA resin content is 40% of a gross mass.In addition, magnetized plastic also can add 0.5%～2% look mother, makes product color abundanter.

Above-mentioned magnetized plastic can prepare in the following way, comprises the steps:

A, get the magnetic of gross mass 50%～70%;

B, get 30%～50% PA resin of gross mass;

C, above-mentioned magnetic and the PA resin mixer of packing into is evenly stirred;

D, mixed magnetic and resin packed into to be heated to 255 ℃-265 ℃ in the plastic granulator and to extrude wire drawing, makes graininess.

Because magnetized plastic of the present invention is a kind of plastic pellet, can be processed into the product of different shape by the mode of injection mo(u)lding, comprise the product that shape is complicated, then it is magnetized, make it have the magnetic field of magnetic therapy, health centre's need.

The invention will be further described below in conjunction with specific embodiment.

Embodiment

Specific embodiment 1: at first get the magnetic of gross mass 50% and the PA resin of gross mass 50%; the mixer of more above-mentioned magnetic and PA resin being packed into evenly stirs; at last above-mentioned mixed magnetic and resin being packed into is heated to 255 ℃ in the plastic granulator and extrudes wire drawing, makes graininess.

Specific embodiment 2: at first get the magnetic of gross mass 70% and the PA resin of gross mass 30%; the mixer of more above-mentioned magnetic and PA resin being packed into evenly stirs; at last above-mentioned mixed magnetic and resin being packed into is heated to 265 ℃ in the plastic granulator and extrudes wire drawing, makes graininess.

Specific embodiment 3: at first get the magnetic of gross mass 60% and the PA resin of gross mass 40%; the mixer of more above-mentioned magnetic and PA resin being packed into evenly stirs; at last above-mentioned mixed magnetic and resin being packed into is heated to 260 ℃ in the plastic granulator and extrudes wire drawing, makes graininess.

For making product color abundanter, also can add the look mother of magnetic and PA resin gross mass 0.5%～2% in the above-mentioned specific embodiment magnetized plastic.
