Problems solved by technology

[0004] 1. Tear resistance, fatigue resistance and safety are poor. Due to the heat-sensitive molding extrusion process and extrusion production process, it is easier to hide tiny bubbles and gel blocks, resulting in bubbles, flower skins, vertical roads and other structures in the hose. Sexual defects, it is easy to break and hurt people when it is stretched at high strength, and it cannot meet the requirements of the rubber hose for physical training
[0005] 2. Poor quality consistency, many appearance defects, simple hose structure, mostly single layer or simple 2-3 layers, mostly one-time extrusion molding and drying, the surface of the hose is prone to bubbles, peeling, vertical lines, and discoloration , leading to poor product quality consistency and many appearance defects in mass production
[0006] 3. The color is not bright

Embodiment 1

[0037] Three-layer composite hose, see figure 1 and image 3 , produced by a simple production process.

[0038] For the specific rubber hose manufacturing device, see figure 1 , process flow image 3 . Immerse the cylindrical stainless steel mold 5 (also can be other metals, plastics, rubber etc.) that handle or formwork 6 has been installed in the calcium chloride aqueous solution tank 1 of 35% w / w for 10 seconds, slowly mention, Dry in an oven at 105°C for 3 minutes, cool to room temperature, then slowly insert natural rubber latex or synthetic latex with a concentration of 50% w / w mixed with blue color paste and vulcanizing agent into tank 2 for 10 seconds, then slowly Slowly lift the mold, turn it slowly for 20 seconds, put it in a 90°C oven to dry for 3 minutes, take it out and cool it to room temperature, and the three-layer composite rubber hose can be completed Figure 5The first layer of blue film①. This mold with the first layer of adhesive film is put into th...

Embodiment 2

[0041] Four-layer nano-reinforced composite hose, see figure 2 and image 3 , produced by a continuous production process.

[0042] First select the bundled flexible cylindrical rubber strip 16 according to the inner diameter of the rubber hose product, press image 3 The process is first assembled on the production line. Tank 9 is loaded with a calcium chloride aqueous solution coagulant with a concentration of 30% w / w; tank 10 is filled with natural rubber latex or synthetic latex with a concentration of 50% w / w of green color paste and vulcanizing agent; tank 11 is loaded with Cooperate with the natural rubber latex or synthetic latex that the concentration of yellow color paste, vulcanizing agent and nano-calcium carbonate particle is 50%w / w; Tank 12 is filled with the concentration that is equipped with blue color paste, vulcanizing agent and nano-calcium carbonate particle is 50% Natural latex or synthetic latex of w / w; Groove 13 is filled with the concentration of 5...

Abstract

The invention discloses a new process for forming and producing multi-layer composite high-elasticity rubber hoses by carrying out emulsion impregnating multiple times. The new process comprises a simple type production process and a continuous production process. According to the new process, manual or continuous mechanical mode is adopted, a mould is impregnated in a coagulator, then dried and cooled to room temperature, and then the mould is impregnated in emulsion and dried so that a layer of emulsion film is formed on the surface of the mould; every time the above operations are repeated, a layer of emulsion film is added on the surface of the dried emulsion film, wherein the coagulator impregnating step can be omitted; multi-layer composite rubber hoses with random thickness can be produced by implementing the combined process of emulsion impregnating and drying repeatedly; multiple layers are composited by heating and vulcanizing by virtue of a vulcanizer mixed in the emulsion; and then demoulding, leaching, final drying, surface treatment and cutting auxiliary process steps are carried out to finally obtain the finished product. Multi-layer composite high-performance rubber hoses with specific length, thickness, property and color can be produced by using the simple type production process and multi-layer composite high-performance rubber hoses with random length, thickness, property and color can be produced by using the continuous production process. Rubber hoses produced by using the new process have high quality and can meet special requirements of physical training.

Description

【Technical field】 [0001] The invention relates to a rubber hose production process, in particular to a new process for producing a multi-layer composite high-elasticity rubber hose. 【Background technique】 [0002] Existing elastic rubber hose is made of latex, rubber or TPR thermoplastic elastomer, which has been widely used in people's daily fitness exercises. With the vigorous development of world sports and the continuous development of training methods by coaches, it will The elastic hose is used in athlete training, which can improve the performance of athletes. The need for professional training puts forward higher requirements for rubber hoses such as high elongation, high resilience, fatigue resistance, tear resistance, and small permanent deformation. At present, the rubber hose produced by the traditional process can no longer meet the needs of physical training products. It is urgent to develop a new process so that the produced rubber hose can meet the needs of ...
