Problems solved by technology

[0005] With the continuous expansion of PVC paste resin gloves, users put forward many special requirements for product grades, especially medical grade PVC paste resin gloves. The original grades can no longer meet the needs of users, forcing enterprises to continuously improve technology and develop new formulations of PVC. Paste resin gloves; after the new PVC paste resin glove formula is developed, it needs to be tested to verify the tensile strength of the finished gloves; however, the existing PVC paste resin glove manufacturers are all directly producing PVC paste resin gloves, and then the production Sampling inspection of the PVC paste resin gloves produced, this method belongs to the inspection of the finished product, not the pre-judgment of the formula, not only the production process is complicated, the inspection process is long, but also the large-scale batch testing consumes more materials, and the waste of resources is serious

Abstract

The invention discloses a tensile strength and break elongation test method of a PVC paste resin glove material. The test method comprises a test piece preparation step and a test piece test step, wherein the test piece preparation step comprises the following steps: (a) mixing raw materials; (b) performing constant-temperature water bath; and (c) forming a test piece. The tensile strength and break elongation test method of the PVC paste resin glove material substitutes a complicated process of a PVC paste resin glove production line, a high-temperature-resistant glass plate is used for substituting a hand mold to prepare the test piece in laboratory, the prepared test piece is similar to the performance of a PVC finished product glove, so that the experimental equipment is simplified, and the material cost and time cost are saved; and important technological instruction data can be provided for manufacturers for manufacturing PVC paste resin powder, and crucial guarantee is provided for improving the technology.

Description

[0001] Technical field: [0002] The invention relates to a test method, in particular to a test method for the tensile strength and elongation at break of a PVC paste resin glove material. [0003] Background technique: [0004] PVC paste resin is referred to as PPVC or EPVC (emulsion paste resin), which is a large category of polyvinyl chloride resin. properties, electrical insulation, flame retardancy and high strength, excellent paste-forming properties, good dispersibility, can be evenly dispersed in plasticizers to become a stable plasticized paste, mainly used in the soft material field of PVC resin, such as PVC paste resin gloves. [0005] With the continuous expansion of PVC paste resin gloves, users put forward many special requirements for product grades, especially medical grade PVC paste resin gloves. The original grades can no longer meet the needs of users, forcing enterprises to continuously improve technology and develop new formulations of PVC. Paste resin g...
