Thermal-insulating sponge production process

Abstract

The invention discloses a thermal-insulating sponge production process, which is characterized by sequentially comprising the following steps of: I, preparing raw materials, including polyester, ceramic powder, a binding agent and a blowing promoter; II, washing a foaming cylinder by using a cleaning agent, then washing twice with pure water, and drying; III, mixing the polyester, the ceramic powder, the binding agent and the blowing promoter in a ratio of 6 to 1 to 1 to 2; stirring a mixture for 30-50 minutes by using a stirring machine; adding the foaming cylinder by dividing the mixture for three times; paving a plastic thin film layer when the mixture is added to a position of 1 / 3 of the foaming cylinder for a first time; paving another plastic thin film layer when the mixture is added to a position of 2 / 3 of the foaming cylinder for a second time; and filling the foaming cylinder for a third time, and sealing in a vacuum manner; and IV, foaming the mixture in the foaming cylinder for 10-12 hours at a foaming temperature of 30-40 DEG C. The thermal-insulating sponge production process provided by the invention has the advantages of simplicity and convenience in operation, high stability and convenience in popularization.

Description

technical field [0001] The invention relates to a sponge, in particular to a production process of a thermal insulation sponge. Background technique [0002] At present, commonly used sponges are divided into three types according to their structure: high-density sponges, medium-density sponges, and low-density sponges. Among them, the high-density sponge has many holes and is very full. Because of its good air permeability and elasticity, it is often used to make sound-absorbing cotton, sofa cushions, soft bags and other materials. Weaknesses, for example: most of them do not have the property of heat preservation, or the manufacturing process of the heat preservation sponge with heat preservation property also has complex process, poor stability, and the defects and problems that are difficult to popularize. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production process of thermal insulation sponge which...

Among them, the high-density sponge has many holes and is very full. Because of its good air permeability and elasticity, it is often used to make sound-absorbing cotton, sofa cushions, soft bags and other materials. Inadequacies, for example: most of them do not have the characteristics of heat preservation, or the manufacturing process of heat preservation sponges with heat preservation characteristics still has defects and problems such as complicated process, poor stability, and difficulty in popularization
