Embodiment 1

[0064] Such as figure 1 As shown, the composite material for the operating table is formed by laminating the PVC film 1 and the skeleton material layer 2 at a high temperature of 200°C. Wherein, the skeleton material layer 2 is in the shape of mesh cloth and is made of 55D high-strength polyester yarn and is woven by biaxial warp knitting; the PVC film 1 has a thickness of 18 yarns, and it is made of the following raw materials in parts by weight: PVC resin powder 100; plasticizer DINP50; epoxy soybean oil 1; barium zinc stabilizer 2; antibacterial agent 1; rutile titanium dioxide 0.2. In this embodiment, the preferred antibacterial agent is a pyridylisothiourea compound.

[0065] The processing technology of the composite material for the operating table is composed of three parts: the processing technology of the skeleton material layer 2, the calendering technology of the PVC film 1 and the product processing technology. The processing technology of the skeleton material ...

Embodiment 2

[0098] The PVC film 1 calendering process comprises the following steps: A, batching weighing: each raw material is weighed batching by weight;

[0099] B. Stirring and mixing: Pour the ingredients into the mixer, control the temperature to 90°C, the stirring speed is 125r / min, and the stirring time is 100s; then raise the temperature to 130°C, the stirring speed is 590r / min, and the stirring time is 250s; then cool down to 65°C, the stirring speed is 350r / min, and the stirring time is 180s;

[0100] C. Banbury mixing: the control temperature is 175°C, and the pressurization time of the top bolt is 6.5 minutes;

[0101] D. Two-r...

Embodiment 3

[0113] The structure and principle of the third embodiment are basically the same as the first embodiment, except that the PVC film 1 is made from the following raw materials in parts by weight: PVC resin powder 100; plasticizer DINP60; epoxy soybean oil 5; barium Zinc stabilizer 8; antibacterial agent 3; rutile titanium dioxide 1.

[0114] The PVC film 1 calendering process comprises the following steps: A, batching weighing: each raw material is weighed batching by weight;

[0115] B. Stirring and mixing: Pour the ingredients into the mixer, control the temperature to 100°C, the stirring speed is 150r / min, and the stirring time is 100s; then raise the temperature to 135°C, the stirring speed is 630r / min, and the stirring time is 250s; then cool down to 70°C, the stirring speed is 400r / min, and the stirring time is 180s;

[0116] C. Banbury mixing: the control temperature is 180°C, and the pressurization time of the top bolt is 7 minutes;

[0117] D. Two-roll pre-plasticiza...

Abstract

The invention provides a composite material for an operating table and a processing technology thereof, belongs to the fields of light industry and textile industry and solves the problem of low fitting fastness of an existing composite material. The composite material for the operating table is prepared from a PVC (Polyvinyl Chloride) film and a meshy framework material layer, wherein the PVC film and the framework material layer are adhered together under a high temperature of 200 DEG C. The processing technology of the composite material for the operating table comprises a framework material layer processing technology, a PVC film calendering technology and a product processing technology, wherein the PVC film calendering technology comprises the following steps: A, burdening and weighing; B, stirring and mixing; C, banburying; D, two-roller pre-plasticizing; E, filtering; F, four-roller calendering; G, extracting; H, cooling and sizing; I, rolling; the product processing technology comprises the following steps: J, preheating of the framework material layer and the PVC film; K, high-temperature fitting; L, cooling, sizing and edge cutting; M, retracting. The composite material for the operating table and the processing technology thereof, provided by the invention, have the advantage that the adhesion degree of the composite material can be increased.

Description

technical field [0001] The invention belongs to the field of light industry and textiles, and relates to a composite material, in particular to a composite material for an operating table and a processing technology thereof. Background technique [0002] Flexible composite materials are one of the most in-demand varieties of coated fabrics for industrial use, and their uses can be found in agriculture, industry, transportation, satellite TV, medical and even household applications. Flexible composite materials are composed of two or more materials, and according to different materials, composite materials are divided into polymer matrix composites, metal matrix composites and ceramic matrix composites. [0003] The processing of existing flexible composite materials generally uses a paste-free lamination process of PVC film and base cloth, but the composite materials processed by this process have the disadvantages of low lamination fastness and poor peel strength.
