Problems solved by technology

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

Embodiment 1

[0021] A production process of thermal insulation sponge, the production process sequentially comprises:

[0022] The first step is to prepare raw materials, the raw materials include polyester, ceramic powder, binder and foaming aid;

[0023] The second step is to first use a cleaning agent to clean the foaming cylinder, then use pure water to clean it twice, and dry it;

[0024] The third step is to mix polyester, ceramic powder, binder and foaming aid in a ratio of 6:1:1:2, and stir with a mixer for 40 minutes, and then add it into the foaming cylinder three times. When it reaches one-third of the foaming cylinder, lay a layer of plastic film, add another layer of plastic film when it is added to two-thirds of the foaming cylinder for the second time, fill the foaming cylinder for the third time, and vacuum seal;

[0025] In the fourth step, the mixture was foamed in a foaming cylinder for 11 hours, and the foaming temperature was 35°C.

[0026] To sum up, the present in...

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...
