preparation example Construction

[0032] In the first aspect, the application also provides a preparation method of a multi-layer liquid infusion hose, please refer to figure 1 , the preparation method comprises:

[0033] Step S100, pretreating the circular knitting tube blank;

[0034] Wherein, the step S100 performs pretreatment on the circular woven tube blank, specifically: drying the circular woven tube blank, and the drying treatment temperature is 85°C-93°C. The moisture contained in the fibers of the circular woven tube is fully removed by pretreatment of the circular woven tube. Preferably, the drying treatment temperature can also be 85°C, 90°C, 91°C, 93°C.

[0035] Step S200, pretreating the rubber material and its compounding system;

[0036] Wherein, in the step S200, the rubber material and its compounding system are pretreated, specifically: performing dehumidification treatment on the rubber material and its compounding system, dehumidification treatment.

[0037] The moisture in the rubber...

Embodiment 1

[0045] S1, the circular knitting tube blank is dried in an oven, and the drying temperature is 93°C.

[0046] S2, dehumidify the rubber compound and its compound system through a dehumidifier, and the drying temperature for dehumidification is 80°C.

[0047] S3, using six extruders to simultaneously extrude the pretreated rubber material and its matching system to feed two molds, and form a multi-layer rubber layer of the hose on the pretreated circular knitting tube blank.

[0048] S4, after the formed coated fabric passes through calender rolls, it is put into storage after being cooled, metered and coiled.

Embodiment 2

[0050] S1, the circular knitting tube blank is dried in an oven, and the drying temperature is 85°C.

[0051] S2, dehumidify the rubber compound and its compound system through a dehumidifier, and the drying temperature for dehumidification is 65°C.

[0052] S3, using four extruders to simultaneously extrude the pretreated rubber material and its matching system to feed two molds, and form a multi-layer rubber layer of the hose on the pretreated circular knitting tube blank.

[0053] S4, after the formed coated fabric passes through calender rolls, it is put into storage after being cooled, metered and coiled.

Abstract

The invention discloses a multi-adhesive layer liquid infusion hose and a preparation method thereof. The preparation method comprises the steps that a circular knitting pipe blank is subjected to pretreatment; an adhesive material and a matching system thereof are subjected to pretreatment; and the pretreated circular knitting pipe blank, the pretreated adhesive material and the pretreated matching system of the adhesive material enter thermal coating equipment to be subjected to thermal coating treatment, so that a plurality of adhesive layers of the hose are formed. According to the multi-adhesive layer liquid infusion hose and the preparation method thereof, the technical problems that the hose performance cannot be ensured, and the production process is complex in the prior art are solved, and the technical effects that the multifunctional requirement of the hose is met, the manufacturing process is simple, and the hose performance can be ensured are achieved.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a multi-adhesive liquid infusion hose and a preparation method thereof. Background technique [0002] The structure of the flat-coil liquid transport hose in the prior art is divided into three parts: an inner rubber layer, a circular woven tube blank and an outer rubber layer. This type of hose is divided into three types. The first one is to heat-coat the elastomer material inside and outside the circular knitting tube to form the inner and outer rubber layers of the hose. The disadvantage is that the inner and outer rubber layers of the hose are made of the same material. , it is impossible to achieve different functional requirements for the inner and outer rubber layers; the other is to stick the protective layer and the sealing layer on the inside and outside of the circular knitting tube to form the inner and outer rubber layers of the hose; the third is to heat the inne...
