Anti-cracking wear-resistant material for magnetic toy and preparation method of anti-cracking wear-resistant material
The invention provides a preparation method of an anti-cracking and wear-resistant material for magnetic toys, and relates to the technical field of anti-cracking and wear-resistant materials.Self-made spherical porous silicon carbide powder is added, silicon carbide is a ceramic material with extremely high heat conductivity, and the heat dissipation performance of a rubber material can be remarkably improved by adding the silicon carbide powder; the modified silicon carbide is dispersed in a rubber matrix, so that rubber with low surface energy tends to be adsorbed on the surfaces of silicon carbide particles with high surface energy, the adsorption effect can effectively improve the rubber strength, and rubber molecular chains adsorbed on the surfaces of the spherical silicon carbide particles have certain activity, so that the rubber strength is improved. Under the action of stress, the spherical silicon carbide particles can slide on the surfaces of the spherical silicon carbide particles, so that the stress in the material is redistributed, stress concentration can be avoided, the mechanical property of the rubber is improved, the external friction resistance of the rubber is also improved, and the wear resistance of the rubber is improved.
本发明提供了一种磁性玩具防开裂耐磨材料的制备方法，涉及防开裂耐磨材料技术领域，本发明通过加入的自制球形多孔碳化硅粉体，由于碳化硅是一种热导率极高的陶瓷材料，它的加入可以显著地提高橡胶材料的散热性能，而且本发明将改性后的碳化硅分散在橡胶基体中，从而利用低表面能的橡胶倾向于吸附在高表面能的碳化硅颗粒表面上，这种吸附作用可以有效地提高橡胶强度，并且吸附于球形碳化硅颗粒表面的橡胶分子链有一定活动能力，在应力作用下，能够在球形碳化硅粒子表面产生滑动，从而使材料中的应力重新分布，可以避免了应力集中，从而提高了橡胶的力学性能，也提高橡胶抵抗外界摩擦的能力，有利于提高其耐磨性。
