Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a graphene anti-static mattress foaming material.
Background
Static electricity is formed by the redistribution of charges caused by friction, and also by the mutual attraction of charges. In general, the positive charge of the nucleus is equal to the negative charge of the electron, and the positive and negative charges are balanced, so that the nucleus does not exhibit electric properties. However, if electrons are forced off the orbit, an unbalanced electron distribution is caused, such as substantial tribocharging, which is a process causing an imbalance of positive and negative charges. When two different objects are in contact with each other and rub against each other, electrons of one object are transferred to the other object, which is positively charged due to the lack of electrons, while the other object gets some remaining electrons and is negatively charged, which is charged with static electricity.
The first hazard of static electricity arises from interactions with charged bodies; the second major hazard is the potential for explosion due to electrostatic sparks igniting certain flammable objects. The electrostatic shock only occurs in the instant, the current passing through the human body is the instantaneous impact current, and the damage of the instantaneous impact current mainly represents three aspects of direct injury, secondary injury and mental stress. When a human body is subjected to electric shock, mental stress occurs, and the consequences of misoperation, high-altitude falling, falling injury or damage caused by touching machinery occur.
Research shows that the static electricity has greater danger to the old, the weak, the sick and the pregnant people, and can interfere the membrane potential of red blood cells to cause the aggregation of the red blood cells in blood vessels, so that the middle-aged and the elderly are easy to suffer from myocardial infarction or cerebral thrombosis; the static electricity can cause the reduction of the progestogen level in the pregnant women, and then cause abortion or premature delivery; static electricity inhibits the production of sex hormones in middle-aged and elderly men, causing premature aging and male sexual dysfunction.
The graphene is sp2The hybridized and connected carbon atoms are tightly packed into a new material with a single-layer two-dimensional honeycomb lattice structure. The graphene has excellent optical, electrical and mechanical properties, has important application prospects in the aspects of materials science, micro-nano processing, energy, biomedicine, drug delivery and the like, can greatly improve the mechanical properties of rubber by being filled in a small amount when being used as a reinforcing material of the rubber, can show good electrical and thermal properties, and can be used as a very ideal medical nano material.
Therefore, the research on the graphene and rubber composite material is developed, and the method has great significance for improving the overall level of the rubber industry in China. However, in the actual production process, the dispersion of graphene in the rubber matrix is always a bottleneck troubling the graphene rubber composite material, and due to the surface tension and self-aggregation, the bonding force between rubber and graphene is very low, and the graphene is easy to separate, so that the performance of the composite material is greatly reduced, and the expected effect cannot be achieved.
In order to solve the above problems, it is necessary to develop a graphene anti-static mattress foam material.

Based on the prior art, the invention aims to provide the graphene anti-static mattress foaming material which has the advantages of static resistance, bacteria resistance, no toxicity, high toughness, good elasticity, difficult deformation, easy cleaning and the like, so that the graphene anti-static mattress foaming material has a better using effect when being used as a mattress.
In order to achieve the above purpose, the invention adopts the technical scheme that:
the graphene antistatic mattress foaming material comprises the following raw materials in parts by weight: 60-70 parts of natural rubber, 10-20 parts of ethylene propylene diene monomer, 15-25 parts of POE (polyolefin elastomer), 0.5-10 parts of graphene, 3-8 parts of white carbon black, 2-10 parts of an antistatic agent, 3-8 parts of zinc oxide, 1-4 parts of zinc stearate, 0.5-2 parts of stearic acid, 1.0-2.5 parts of an odorless cross-linking agent and 1-6 parts of a foaming agent.
In order to better realize the invention, further, the basic composition of the foaming material comprises the following raw materials in parts by weight: 65 parts of natural rubber, 15 parts of ethylene propylene diene monomer, 20 parts of POE elastomer, 4 parts of graphene, 5 parts of white carbon black, 5 parts of antistatic agent, 5 parts of zinc oxide, 3 parts of zinc stearate, 1 part of stearic acid, 1.5 parts of tasteless cross-linking agent and 3 parts of foaming agent.
In order to better implement the present invention, further, the POE elastomer is one of an ethylene-octene copolymer, an ethylene-butene copolymer, and an ethylene-hexene copolymer.
In order to better implement the invention, further, the antistatic agent is one of ethoxylated aliphatic alkylamine, alkyl sodium sulfonate, alkyl imidazoline salt, polyethylene oxide and polyether ester amide.
In order to better implement the invention, further, the odorless crosslinking agent is di-tert-butylperoxydiisopropylbenzene.
In order to better realize the invention, the foaming agent is one of azodicarbonamide, diphenyl sulfonyl hydrazide ether and p-toluene sulfonyl hydrazide.
Advantageous effects
The invention has the following beneficial effects:
(1) the foaming material contains graphene which is used as a reinforcing material of rubber, can greatly improve the mechanical property of the rubber by filling a small amount of the graphene, can show good electrical and thermal properties of the graphene, and is an ideal rubber nano material; the POE elastomer has excellent low-temperature impact resistance, low specific gravity, cleanness, compatibility with various basic polymers, excellent flexibility and puncture resistance, excellent elongation and high elasticity, good light transmittance and excellent electric insulation performance.
(2) The antistatic agent used in the foaming material is an internal mixing type antistatic agent, which is a type of antistatic agent added into rubber in the processing process of products. Ethoxylated fatty alkylamines, sodium alkylsulfonates and alkylimidazoline salts are surfactants which, when the mixture is in the molten state, form the densest alignment of the antistatic molecules at the interface between the resin and the air or between the resin and the metal, with the lipophilic groups extending towards the inside of the resin and the hydrophilic groups towards the outside of the resin. After the resin is cured, the hydrophilic groups on the molecules of the antistatic agent are arranged towards the air side to form a monomolecular conductive layer. During processing and use, the molecular layer of the antistatic agent on the surface of the material is damaged through stretching, rubbing, washing and the like, and the antistatic performance is reduced. However, unlike the external coating type antistatic agent, molecules of the antistatic agent inside the material continuously migrate to the surface after a certain period of time, so that the defective portion is restored and the antistatic effect is exhibited again. Polyethylene oxide and polyether ester amide are permanent antistatic polymer agents, which are mainly characterized in that the surface layer of the product is distributed in a fine layer or rib shape to form a conductive surface layer, and the surface layer is distributed in a nearly spherical shape in the center to form a so-called core-shell structure, and static charges are leaked by using the core-shell structure as a passage. The antistatic agent can endow the surface of the material with certain lubricity, reduce the friction coefficient, inhibit and reduce static charge generation, and has the characteristic of permanent antistatic.
(3) The cross-linking agent selected in the foaming material is di-tert-butylperoxy diisopropylbenzene, no pungent odor is generated in the operation process and the prepared product, the rubber material is added during mixing, and under the condition of the same cross-linking effect, the addition amount is only 1/3-2/3 of DCP, so that the dosage is reduced, and the foaming material is more environment-friendly; the foaming agent is one of azodicarbonamide, diphenyl sulfonyl hydrazide ether and p-toluene sulfonyl hydrazide, has stable property during storage, is non-toxic and non-combustible, has better compatibility with rubber during mixing, is decomposed to generate nitrogen gas to form closed holes or connected holes, has small shrinkage rate, is not easy to deform, and ensures that the holes are not easy to collapse; the additive is not easy to exude in the finished product after being used, does not generate side reaction with other materials, is nontoxic and harmless after being used for a long time, and has no pollution and influence on the family environment.
