Flame-retardant sponge

Abstract

The invention discloses a flame-retardant sponge. The flame-retardant sponge raw materials comprise the following components in parts by weight: 90-110 parts of polyether polyol, 45-65 parts of toluene diisocynate, 3-5 parts of water, 1-5 parts of a foaming agent, 1-3 parts of modified silicone oil, 0.1-10 parts of stannous octoate and 1-35 parts of a flame retardant, wherein the flame retardant comprises a silicon-based mesoporous material. The flame-retardant sponge provided by the invention has the following advantages and effects that polyether polyol, toluene diisocynate, modified silicone oil, stannous octoate and water are added into flame-retardant sponge raw materials, wherein the stannous octoate exerts a catalytic effect; and the flame retardant in the sponge flame-retardant rawmaterial comprises a silicon-based mesoporous material, carbon nano tubes and basalt fibers, wherein the silicon-based mesoporous material and the basalt fiber are dispersed in the flame-retardant sponge, and the synergistic effect is achieved, so that the flame-retardant sponge has good flame retardancy, and the effects of good flame-retardant property, no toxicity and no ordour, safety and environment protection are achieved.

Description

technical field [0001] The invention relates to the field of sponge products, in particular to a flame-retardant sponge. Background technique [0002] Sponge is a porous material made of foamed plastic polymers that is widely used in everyday life, such as mattresses, sofas, car interiors, child safety seats in cars, strollers, and more. When a fire breaks out, ordinary sponges and sponge products are easy to burn, causing the fire to spread rapidly, increasing casualties and property losses. Infants and young children do not have the ability to save themselves when encountering a fire, and are often vulnerable to greater injuries when encountering a fire. Therefore, for infant products such as baby carriages, sponges and sponge products in child safety seats, better resistance is required. Combustibility, such as no open flame when burning, shortening the burning time, delaying burning, blocking smoke and causing the burning part to self-extinguish. [0003] The Chinese p...

Problems solved by technology

[0004] However, the above flame retardant sponge has the following disadvantages: although the flame retardant diphenyl phosphate is added to the flame retardant sponge, it is easy to soften and deform after being heated. Once it is ignited, it will easily cause the spread of the flame, and the flame retardant effect is not good.
