Problems solved by technology

However, soft PVC hoses need to use a large amount of low-molecular-weight plasticizers to reduce their hardness during production, which leads to disadvantages such as poor elasticity of the material, easy plastic deformation, large loss of mechanical properties, and poor durability.

Embodiment 1

[0024] The polyvinyl chloride PVC of embodiment one is the S-65 type that Formosa Plastics Industry (Ningbo) Co., Ltd. produces, and described dioctyl phthalate DOP is the common plasticizer that Zhenjiang Liancheng Chemical Industry Co., Ltd. produces, The hot melt is 480 type produced by Puliyou Polymer (Fujian) Co., Ltd., and the calcium / zinc composite stabilizer is A-300 produced by Suzhou Ronghe Chemical Co., Ltd. type.

Embodiment 2

[0025] Embodiment 2 Compared with Embodiment 1, the raw materials are different, and the plasticizer adopts diisononyl phthalate DINP, which is a plasticizer produced by Taizhou Liancheng Chemical Industry Co., Ltd.

[0026] Embodiments 3 and 4 Compared with Embodiment 2, dioctyl adipate DOA is added to the raw material, which is a cold-resistant plasticizer, so that the elastic PVC hose can still maintain good performance at relatively low temperatures. Add an appropriate amount of deodorant, produced by Shanghai Ziyu Chemical New Material Co., Ltd., to effectively remove the odor of polymer materials during processing.

[0027] Above-mentioned embodiment all produces by following production method:

[0028] (1) Raw material preparation: Weigh each component according to the dosage ratio of each component in the raw material formula;

[0029] (2) After the raw materials are prepared, put them into the mixer and blend them for 14 minutes at 110°C, then extrude and granulate i...

Abstract

The invention relates to a PVC (Polyvinyl Chloride) hose with elasticity and a production method thereof. The PVC hose with elasticity is prepared from the raw materials in parts by weight: 95-100 parts of PVC, 45-60 parts of plasticizer, 18-20 parts of thermosol and 1.6-3.5 parts of calcium / zinc complex stabilizer. The PVC hose with elasticity is prepared through preparing the raw materials, then, mixing the raw materials, granulating and extruding. The thermosol has relatively high mechanical properties and good elasticity, wear resistance, oil resistance, cold resistance and the like in a wide hardness range, so that the properties of PVC are excellently improved by the thermosol, and thus, the elastic PVC hose with excellent comprehensive properties is produced.

Description

technical field [0001] The invention relates to an elastic PVC hose. Background technique [0002] In the prior art, polyvinyl chloride (PVC) is a kind of general-purpose plastic, and its price is low, and advantage is outstanding, output is big, is widely used in various industries of national economy. However, soft PVC hoses need to use a large amount of low-molecular-weight plasticizers to reduce their hardness during production, which leads to disadvantages such as poor elasticity of the material, easy plastic deformation, large loss of mechanical properties, and poor durability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elastic PVC hose. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is: a flexible PVC hose, in parts by weight, the raw material formula of the flexible PVC hose includes: [0005] 95~100 parts of polyvinyl chl...
