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 Construction

[0022] The PVC composite material used to make bags, by weight, includes the following components:

[0023] Dioctyl phthalate, sodium stearate, zinc oxide and PVC powder with a mass percentage of 5:5:1:25 are mixed by magnetic stirring to form 90 parts of PVC preparatory material;

[0024] The organophosphine silane coupling agent containing 5% by weight of silicon dioxide is diluted with ethylene glycol to 15% of the dilute solution, adding 15 parts of modified silicon dioxide formed by stirring and mixing silicon dioxide;

[0025] 3 parts of dibutyltin dilaurate;

[0026] 3 parts of butyl stearate;

[0027] Sucrose tribehenate 9 parts

[0028] The preparation process of the PVC composite material used to make bags is as follows: Step 1, batching, taking dioctyl phthalate, sodium stearate, zinc oxide and PVC powder with a mass percentage of 5:5:1:25 through Magnetic stirring and mixing to form 90 parts of PVC preparatory material, then add organophosphine silane coupling a...

Abstract

The invention relates to a PVC composite for bag manufacture. The PVC composite is prepared from components of raw materials in parts by weight as follows: 90-100 parts of a PVC preparation material,5-40 parts of modified silicon dioxide, 1-3 parts of a stabilizer, 1-5 parts of a lubricant and 1-9 parts of a processing aid. The PVC composite has the benefits as follows: silicon dioxide modified with an organic phosphine silane coupling agent is added, so that the tensile performance and the wear-resistant strength of the prepared composite for PVC bags are improved, and the service life of the bags is greatly prolonged; raw materials of the PVC composite comprise a processing aid sucrose tribehenate which can realize elimination reaction of micromolecules with main chains not breaking when thermal degradation of PVC is inhibited; secondarily, tribehenin in raw materials of the PVC composite and sucrose tribehenate can have a synergistic interaction, thermal degradation of PVC is further inhibited, tetramethylol acetylenediurea in raw materials of the PVC composite can inhibit light degradation of PVC, and the effects of good ageing resistance, high weather fastness and long service life are realized.

Description

technical field [0001] The invention relates to the field of luggage materials, in particular to a PVC composite material for making luggage 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 technical problem to be solved by the present invention is to address the above-me...
