[0026] refer to figure 1 , this implementation case is a method for preparing far-infrared physiotherapy paste by irradiating foaming, and the preparation method of this kind of far-infrared physiotherapy paste comprises the following steps:

[0027] S1. The ratio of plastic raw materials is according to the weight EVA: 5-100, EPDM: 1-65, PE: 0-25, ADC: 10-25, ceramic powder: 10-70, titanium dioxide powder: 2-15, silicon dioxide Powder: 1-15, dimethyl silicone oil: 0.5-2.0, stearic acid: 0.5-1.5, TAIC: 0.01-5.0, zinc oxide: 2-5 ratio, foaming agent, additives and ceramic powder for mixing , put into the internal mixer and refine into homogeneous rubber balls;

[0028] S2. Put the rubber balls of S1 on the open mill to plasticize the wrapping roll, add zinc oxide, and evenly knead into a sheet by making a triangular wrapping process;

[0029] S3, irradiating the sheet of S2 with electron accelerator rays to cross-link the sheet;

[0030] S4, the cross-linked sheet of S3 is h...

Embodiment example 1

[0039] A method for preparing self-adhesive far-infrared physiotherapy paste by irradiation foaming, comprising the following steps:

[0040] 1) Weigh the materials in the following table for later use;

[0041]

[0042]

[0043] 2) Put all the raw materials except zinc oxide in step 1) into the internal mixer for mixing, when the material temperature reaches 150°C, count for 5 minutes, and unload after refining into homogeneous rubber balls;

Abstract

The invention relates to the technical field of irradiation synthesis of medical instrument physiotherapy patch flaky materials, in particular to a method for preparing a far infrared physiotherapy patch through irradiation foaming. The preparation method of the far infrared physiotherapy patch comprises the following steps: S1, mixing a plastic raw material, a foaming agent, an auxiliary agent and ceramic powder, and putting the mixture into an internal mixer to be mixed into homogeneous rubber balls; S2, plastifying and rolling the rubber balls in the step S1 on an open mill, adding zinc oxide, and enabling the rubber balls to be subjected to uniform open milling through a triangular bag making process to form sheets; S3, performing ray irradiation on the sheet in the S2 through an electron accelerator to obtain a cross-linked sheet; S4, heating the cross-linked sheet obtained in the step S3 into a foamed sheet through a press vulcanizer; S5, coating the single face of the foamed sheet in the S4 with a pressure-sensitive adhesive and covered with a release film, and forming a self-adhesive sheet; and S6, cutting the self-adhesive sheet prepared in the step S5 into the foamed self-adhesive far-infrared physiotherapy patch with a fixed shape. The foaming material has the beneficial effects that a process guarantee is provided for material foaming, the softness and elasticity are good, and the bonding strength is high.

Description

technical field [0001] The invention relates to the technical field of radiation-synthesized medical device physiotherapy sticking sheet materials, in particular to a method for preparing far-infrared physiotherapy sticking by irradiating foaming. Background technique [0002] Cervical spondylosis, frozen shoulder, lumbar disc herniation, lumbago and leg pain, hyperosteogeny, arthritis, lumbar muscle strain, soft tissue injury, myofibritis, etc. are common clinical chronic diseases. The main clinical manifestations are neck, shoulder, waist, Pain in the legs and joints, accompanied by pain and numbness, unfavorable activities, dizziness and tinnitus, etc., mostly occurs in the middle-aged and elderly people, and those who work with computers who maintain one posture for a long time. The course of the disease is long and the condition is very easy Repeatedly, if it cannot be treated in time, limb dysfunction will occur, which will lead to limited activities and seriously affe...
