Embodiment 1

[0028] A preparation method of low-smoke foaming sponge, comprising the following steps:

[0029] 1) Put the polyethylene resin into the plastic internal mixer first, and when the internal mixing temperature rises to 150°C, add Evapine rubber, and discharge it after internal mixing for 2-5 minutes, which is the foamed sponge matrix;

[0030] 2) Mix the natural rubber latex, vulcanizing agent, accelerator and anti-aging agent evenly, and let it stand at room temperature for 15 minutes to obtain the mixed natural rubber latex. Add foam stabilizer and foaming agent to the mixed natural rubber latex, stir and foam, and then add retarded rubber Coagulant and active agent, obtain foam latex;

[0031] 3) Preheat the training machine for 6 minutes, then mix the foam masterbatch prepared in step 1 and the foam latex prepared in step 2 with dispersant, antioxidant, protective wax, softener, reinforcing agent and Put the anti-hydrolysis agent into the open mixer, then mix for 10-20 minu...

Embodiment 2

[0034] A preparation method of low-smoke foaming sponge, comprising the following steps:

[0035] 1) Put the polyethylene resin into the plastic internal mixer first, and when the internal mixing temperature rises to 150°C, add Evapine rubber, and discharge it after internal mixing for 2-5 minutes, which is the foamed sponge matrix;

[0036] 2) Mix the natural rubber latex, vulcanizing agent, accelerator and anti-aging agent evenly, and let it stand at room temperature for 15 minutes to obtain the mixed natural rubber latex. Add foam stabilizer and foaming agent to the mixed natural rubber latex, stir and foam, and then add retarded rubber Coagulant and active agent, obtain foam latex;

[0037] 3) Preheat the training machine for 6 minutes, then mix the foam masterbatch prepared in step 1 and the foam latex prepared in step 2 with dispersant, antioxidant, protective wax, softener, reinforcing agent and Put the anti-hydrolysis agent into the open mixer, then mix for 10-20 minu...

Embodiment 3

[0041] A preparation method of low-smoke foaming sponge, comprising the following steps:

[0042] 1) Put the polyethylene resin into the plastic internal mixer first, and when the internal mixing temperature rises to 150°C, add Evapine rubber, and discharge it after internal mixing for 2-5 minutes, which is the foamed sponge matrix;

[0043] 2) Mix the natural rubber latex, vulcanizing agent, accelerator and anti-aging agent evenly, and let it stand at room temperature for 15 minutes to obtain the mixed natural rubber latex. Add foam stabilizer and foaming agent to the mixed natural rubber latex, stir and foam, and then add retarded rubber Coagulant and active agent, obtain foam latex;

[0044] 3) Preheat the training machine for 6 minutes, then mix the foam masterbatch prepared in step 1 and the foam latex prepared in step 2 with dispersant, antioxidant, protective wax, softener, reinforcing agent and Put the anti-hydrolysis agent into the open mixer, then mix for 10-20 minu...

Abstract

The invention relates to the technical field of foamed sponge and discloses a method for preparing low-smoke foamed sponge. The low-smoke foamed sponge comprises the following raw materials in parts by weight: 70-100 parts of polyethylene resin, 30-50 parts of levapren rubber, 20-30 parts of natural latex, 2-5 parts of a vulcanizing agent, 0.5-2.5 parts of an accelerant, 0.5-1.5 parts of an anti-aging agent, 0.5-3 parts of a retardant gelatinizing agent, 1-5 parts of a foam stabilizer, 7-9 parts of an activator, 2-3 parts of a dispersant, 3-5 parts of a foaming agent, 2-3 parts of an antioxidant and 2-3 parts of a protective wax. Due to addition of the levapren rubber raw material, the levapren rubber has very excellent flame retardance and can be used as a flame retardant in a product formula, high flame retardance requirements can be met without a halogen flame retardant, then the foamed sponge is liable to generate a great amount of smoke, the purpose of environment pollution prevention is achieved, and the prepared foamed sponge has properties of rubber and is good in elasticity, good in rebound resilience and not easy to deform.

Description

technical field [0001] The invention relates to the technical field of foam sponges, in particular to a method for preparing low-smoke foam sponges. Background technique [0002] Foaming sponge is like foaming bread. It can be foamed by mechanical equipment, or it can be artificially surrounded by wooden boards. The foamed cotton is like a large square bread. Use a slicer to go through the slicing process. The cutting thickness is required, and the softness and hardness of the foamed cotton can also be adjusted. Seat cotton generally adopts 25-8kg / m3 density, and others use 20-22kg / m3 density. Although the softness and hardness of the sponge are directly related to the density, they are also related to different additive formulas. Therefore, the industry is divided into high elasticity, gray Ultra, black gray ultra, soft cotton. When designing and using the product, it should be rationally and scientifically matched according to different shapes and structures. Generally, ...
