Embodiment 1

[0018] The environmentally safe PE foam floor mat using OBSH foaming agent includes the following raw materials by weight: recycled LDPE 50Phr, 1000 mesh ground calcium carbonate 20Phr, foaming agent 7.0Phr, zinc oxide 3.0Phr, stearic acid 1.0 Phr, pigment 1.0-3.0Phr.

[0019] Among them, recycled LDPE is the main material, and the high-pressure polyethylene film is recycled and granulated as an environmentally friendly recycled high-pressure material. The high-pressure polyethylene foamed floor mat has good flexibility, elasticity, and low cost.

[0020] The foaming agent is 4,4'-oxidized bisbenzenesulfonazine OBSH foaming agent, which is used to adjust the hardness and density of foamed floor mats. Its chemical molecular structure formula is The decomposition temperature is 150-160°C, the decomposition gas is nitrogen, and does not contain formamide. The thermal decomposition equation is as follows:

[0021]

[0022] The peroxide cross-linking agent is bis-tert-butylper...

Embodiment 2

[0028] Except that each raw material consumption is different, other is with embodiment 1, specifically as follows:

[0029] The environmentally safe PE foam floor mat using OBSH foaming agent includes the following raw materials calculated by weight: recycled LDPE 60Phr, 1000 mesh ground calcium carbonate 25Phr, foaming agent 8.0Phr, zinc oxide 3.0Phr, stearic acid 1.0Phr , pigment 1.0-3.0Phr.

Embodiment 3

[0031] The environmentally safe PE foam floor mat using OBSH foaming agent includes the following raw materials calculated by weight: recycled LDPE 55Phr, 1000 mesh ground calcium carbonate 30Phr, foaming agent 9.0Phr, zinc oxide 3.0Phr, stearic acid 1.0 Phr, pigment 1.0-3.0Phr.

Abstract

The invention discloses an environment-friendly and safe PE foam floor mat using an OBSH foaming agent and a preparation method thereof. The following raw materials are calculated by weight: 50-60 Phr of regenerated LDPE, 20-30 Phr of heavy calcium carbonate of 1000 mesh, 20-30 Phr of heavy calcium carbonate of 1000 mesh, Foaming agent 7.0‑9.0Phr, peroxide crosslinking agent 0.8Phr, zinc oxide 3.0Phr, stearic acid 1.0Phr, pigment 1.0‑3.0Phr; Formamide-free PE foam floor mats are prepared through the processing process, and the traditional foaming agent AC is replaced by OBSH foaming agent, which avoids the decomposition of AC to produce harmful substance formamide, and not only satisfies its various physical properties It has good elasticity, easy coloring, and is environmentally safe, non-toxic, tasteless, harmless to the human body, and has significant practical value.

Description

technical field [0001] The invention relates to a foamed floor mat, in particular to an environment-friendly and safe PE foamed floor mat using an OBSH foaming agent and a preparation method thereof. Background technique [0002] PE foam floor mats are more and more popular among people because of their light density, soft material and good resilience. The traditional PE foam floor mat is foamed by using the foaming agent AC to generate gas after decomposition, and the decomposition product of AC will produce the harmful substance formamide. Formamide is a toxic substance that is slightly irritating to the skin of the human body, easily causes allergies, and is harmful to the human body. At present, most of the PE foam floor mats are used for crawling and playful use of infants and young children. Hazardous substances such as formamide are more harmful to it. How to replace the blowing agent AC with a new environmentally friendly and safe blowing agent, so as to obtain a fo...
