Problems solved by technology

PVC is the English abbreviation of polyvinyl chloride. PVC is a white powder with an amorphous structure. The degree of branching is small. Or after long-term sunlight exposure, it will decompose to produce hydrogen chloride, and further autocatalyze and decompose, causing discoloration, rapid decline in physical and mechanical properties, and poor aging resistance

Embodiment 1

[0020] Example 1: A PVC composite material used for bags, the components and contents of the raw materials are shown in Table 1, and the unit of each component in Table 1 is kg. Wherein the stabilizer is dibutyltin dilaurate, the lubricant is butyl stearate, and the processing aid is sucrose tribehenate.

[0021] The preparation process of the PVC composite material used for bags is as follows: the following steps are included, step 1, batching, taking each component in the raw material, heating to 80°C, and stirring evenly; step 2, extruding, cooling the material in step 1 to 30 ℃, sent to the extruder for extrusion, the heating temperature of the extruder is controlled at 140-150 ℃, and the plasticizing temperature of the material is controlled at 150-180 ℃; Step 3, calendering, calendering the material extruded by the extruder, calendering roller The temperature is controlled at 150-180°C; step 4, cooling and winding, after the sheet calendered by the calender is cooled, wi...

Embodiment 2

[0022] Embodiment 2: A kind of PVC composite material that is used for luggage, the difference with embodiment 1 is that each component of raw material and content are as shown in table 1, and wherein, stabilizer is di-n-octyltin dilaurate, lubricant It is glycerol monooleate, and the processing aid is sucrose tribehenate.

Embodiment 3

[0023] Embodiment 3: a kind of PVC composite material that is used for luggage, the difference with embodiment 1 is that each component of raw material and content are as shown in table 1, and wherein, stabilizing agent is dibutyltin maleate, and lubricant is Monoglyceride Stearate.

Abstract

The invention discloses a PVC (polyvinyl chloride) composite material for bags and suitcases. The PVC composite material is prepared from the following raw material ingredients in parts by weight: 80to 95 parts of PVC, 0.9 to 3 parts of stabilizing agents, 0.5 to 3 parts of lubricating agents and 1 to 9 parts of processing aids, wherein the processing aid is sucrose tribehenate. The PVC compositematerial has the following advantages and effects that the raw materials of the PVC composite material include the processing aid of sucrose tribehenate, so that the elimination reaction of micromolecules without main chain fracture during the PVC thermal degradation can be inhibited; secondly, the tribehenate in the PVC composite material can take a synergistic interaction effect with the sucrose tribehenate; the thermal degradation of the PVC is further inhibited; thirdly, tetramethylol acetylenediurea in the PVC composite material can inhibit the light degradation of the PVC; the effects of good anti-aging performance, high weather resistant performance and long service life are achieved.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a PVC composite material used for bags and a preparation process thereof. Background technique [0002] Luggage is a general term for bags used to hold various things, including handbags, clutches, satchels, trolley cases, etc. PVC materials are mostly used in the production of bags, for the preparation of decorative parts, and are also directly made of PVC materials. Trolley case etc. PVC is the English abbreviation of polyvinyl chloride. PVC is a white powder with an amorphous structure. The degree of branching is small. Or after long-term sunlight exposure, it will decompose to produce hydrogen chloride, and further autocatalyze the decomposition, causing discoloration, rapid decline in physical and mechanical properties, and poor aging resistance. Contents of the invention [0003] The object of the present invention is to provide a PVC composite mate...
