Silicone rubber synthetic leather for outdoor furniture and manufacturing technology of silicone rubber synthetic leather

Abstract

The invention discloses silicone rubber synthetic leather for outdoor furniture. The silicone rubber synthetic leather for the outdoor furniture comprises substrate cloth which is covered with a silicone rubber layer for the outdoor furniture; the silicone rubber layer is covered with a matt hand feeling oil surface layer for the outdoor furniture and is prepared from the following raw materials in parts by mass: 100-200 parts of vinyl silicone rubber-based rubber, 5-10 parts of high vinyl silicone oil, 10-20 parts of vinyl MQ resin, 5-15 parts of methyl MQ resin, 5-20 parts of hydrogen-contained silicone oil, 1-2 parts of tackifier, 0.1-0.5 part of platinum catalyst, 5-20 parts of color paste pigment and 0.02-0.1 part of inhibitor. Liquid silicone rubber is used to prepare the outdoor used synthetic leather; the synthetic leather can well meet the requirement of the outdoor furniture to the synthetic leather, has the advantages of ageing resistance, hydrolysis resistance, yellowing resistance and the like and has the characteristics of waterproofness, ventilation, easiness in cleaning, nontoxicity and environmental protection at the same time.

Description

technical field [0001] The invention relates to silicon rubber leather, in particular to a silicon rubber synthetic leather for outdoor furniture and a manufacturing technology of the silicon rubber synthetic leather for outdoor furniture. Background technique [0002] With the development of modern high technology, artificial leather and synthetic leather have achieved rapid growth in product quality, variety and output, and their appearance is gorgeous and colorful, and their performance is getting closer to natural leather, and even surpasses natural leather in some aspects. [0003] Currently used artificial leather and synthetic leather are mainly polyvinyl chloride (PVC) and polyurethane (PU). In order to obtain good comfort, PVC artificial leather will add a large amount of benzoate plasticizers during use. ; PU synthetic leather will discharge a large amount of DMF wastewater and waste, causing great harm to people and the environment. At the same time, these produc...
