Abstract

The invention discloses a rubber water sealing material of a washing machine. The rubber water sealing material comprises the following components: natural rubber, methyl vinyl silicone rubber, fluororubber TP, a thermoplastic elastomer, a modified composite filler, karaya gum, sulphur and calcium carbonate. According to the prepared rubber water sealing material, the modification is carried out,so that the compatibility of inorganic components and high polymer compounds can be improved, the modified composite filler and the substrate raw material components can be closely combined, as a result, the tensile strength and the elongation at break of the rubber water sealing material can be improved; the permanent compression set value is reduced; the comprehensive performances are extremelyoutstanding; and the rubber water sealing material is high in market popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, and in particular relates to a rubber water sealing material for a washing machine. Background technique [0002] The performance of the washing machine is good or bad. In addition to the materials and structure of the washing machine meeting the requirements of the working medium, the choice of sealing material is also very important. The reasonable choice of sealing material is to ensure its normal and orderly operation and reduce maintenance and repair costs. key. With the development of industrial technology and increasingly complex and diverse requirements, sealing materials have also developed rapidly, with more and more types and continuous improvement in physical and chemical properties; however, the comprehensive performance of existing washing machine sealing materials cannot reach Some production requirements, short service life. [0003] "A Washing Machine Rubber Water Sea...
