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 flame retardant properties, and the production process of flame retardant sponges with flame retardant properties still has defects and problems that are complicated and difficult to popularize

Embodiment 1

[0021] A production process of flame retardant sponge, said production process comprises in sequence:

[0022] Step 1: Prepare raw materials, which include polyester, ceramic powder, flame retardant, binder and foaming aid;

[0023] Step 2: First, clean the foam tank with a cleaning agent, then rinse the foam tank with pure water, and dry it;

[0024] Step 3: Mix polyester, ceramic powder, flame retardant, binder and foaming aid in a foaming tank at a ratio of 6:1:1:1:1, and stir for 35 minutes with a stirring device;

[0025] Step 4: Vacuum seal the foaming cylinder, foam the mixture in the foaming cylinder for 25 hours at a foaming temperature of 45° C., and connect the foaming cylinder to an ultrasonic vibration device.

Abstract

The invention discloses a production process of an inflaming retarding sponge. The production process is characterized by comprising the following steps in sequence: step one, preparing raw materials, wherein the raw materials comprise polyester, ceramic powder, fire retardant, binder and foaming promoter; step two, firstly, washing a foaming tank by using a cleaning agent, secondly washing the foaming tank by using pure water, and thirdly drying; step three, mixing the polyester, the ceramic powder, the fire retardant, the binder and the foaming promoter in a ratio of 6:1:1:1:1 in the foaming tank, and stirring for 30-40 minutes by using a stirring device; and step four, sealing the foaming tank in vacuum, foaming the mixture for 20-30 hours in the foaming tank with the foaming temperature of 30-60 DEG C, and connecting the foaming tank with an ultrasonic vibration device. The production process is simple to operate, easy to control and convenient to popularize.

Description

technical field [0001] The invention relates to a sponge, in particular to a production process of a flame-retardant 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. Inadequacies, for example: most of them do not have flame retardant properties, and the production process of flame retardant sponges with flame retardant properties also has complex processes and 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 flame retardant sponge which is easy to operate, easy to control...
