AI Technical Summary

Technical Problem

Existing technologies struggle to effectively suppress the settling of large-diameter, high-density ceramic particles in a molten state while simultaneously ensuring good application flowability and overall coating performance. Conventional methods, such as increasing the viscosity of the coating melt or introducing thixotropic agents, have limited effectiveness, and surface application processes suffer from poor uniformity and weak bonding.

Method used

A ternary thixotropic system is constructed by combining hydrogenated castor oil, polyamide wax micropowder, and fumed silica. Hollow glass microspheres are used to reduce the melt density, and the surface of ceramic particles is modified by silane coupling agent to form a three-dimensional network structure with high yield stress and strong shear thinning, ensuring that the particles are uniformly dispersed and firmly bonded in the melt.

Benefits of technology

It significantly improves the overall performance of hot-melt road marking paint, effectively inhibits the settling of ceramic particles, achieves a balance between anti-slip properties, durability and workability, and ensures uniform suspension of ceramic particles on the coating surface and efficient construction.

Abstract

The application provides a high-slip hot-melt road marking paint composition containing ceramic particles and relates to the technical field of materials, which is prepared from the following raw materials in mass parts: petroleum resin 18-22 parts, plasticizer 4-7 parts, polyethylene wax 1-2 parts, ethylene-vinyl acetate copolymer 2-5 parts, filler 25-35 parts, hollow glass microbead 8-12 parts, ceramic particle 15-22 parts, thixotropic agent 3.1-5.5 parts, silane coupling agent 0.3-0.5 parts, antioxidant 0.1-0.3 parts and pigment 5-8 parts. Through the synergistic effect of ternary thixotropic compound of hydrogenated castor oil-polyamide wax micro powder-fumed silica, hollow glass microbead density reduction and ceramic particle surface modification, the comprehensive performance of the hot-melt marking paint is significantly improved. The high-density large-particle-size ceramic particles are effectively inhibited from settling in the hot-melt state, and the balance between slip resistance, durability and workability is achieved.
