Abstract

PURPOSE: To facilitate the storage and transportation of mica, prevent the scattering in the compounding of a paving material, uniformize the formulation and shorten the formulation time by including inorganic aggregate particles, an organic resin binder and a material containing mica in a high concentration and dispersed in a dispersing agent. CONSTITUTION: Mica having particle diameter of 10-650μm and a thickness of 0.1-30μm and optionally surface-coated with titanium oxide and/or ferric oxide or colored with a pigment is dispersed in an amount of 15-60wt.% in a dispersing agent to obtain a material containing mica in a high concentration. The material is diluted with an organic resin binder. A paving material is produced by mixing the diluted product with glass cullet or glass cullet and one or more kinds of inorganic aggregate particles selected from among gravel, sand, natural stone, ceramic particles, reclaimed concrete scrap and recycled material.

できなくなるからである。The present invention is characterized in that the high-concentration mica-containing material obtained by dispersing the mica in a dispersant is diluted with a binder to adjust the mica content in the paving material. is there. That is, unlike the conventional method, the wet treatment of mica aims to prevent scattering during the preparation of raw materials, achieve uniform dispersion, and facilitate storage and transportation. The content of mica in the high-concentration mica-containing material is set to 15 to 60% by weight. This is because if it is less than 15% by weight, it is separated from the liquid to cause the precipitation of mica, while if it is more than 60% by weight, it becomes impossible to mix it in a uniformly dispersed state.

もよいことは勿論である。In addition, as the dispersant, it is basically preferable to use the same solvent as the binder (for example, when the binder is an epoxy resin, the same epoxy resin solvent) from the viewpoint of uniform dispersion during preparation. Most preferred are other asphalt, epoxy resin, acrylic resin, urethane resin,
One or more selected from bisphenol A alkylene oxide derivatives, alkylene oxide derivatives, polyalkylene glycol benzoate and butyl cellosolve can also be used. In this case, impact resistance and water resistance can be improved by using a bisphenol A alkylene oxide derivative, viscosity-temperature characteristics can be improved by using an alkylene oxide derivative, and polyalkylene glycol benzoate ester is used. It is also possible to obtain additional effects such as improving plasticity. In addition, it goes without saying that a curing agent such as polyamine or polycarboxylic acid anhydride may be added in an appropriate amount.

As a result of making a material and examining the separated state of the obtained high-concentration mica-containing material after 24 hours, it was confirmed that the paste liquid did not separate at all and maintained a homogeneous state. In addition, it was confirmed that the prepared raw materials were easy to store and transport, and both were extremely easy to handle. Further, by using this high-concentration mica-containing material, 1.0% by weight of mica and 52.0% of gravel

A pavement material was prepared by mixing so as to have a mixing ratio of (main agent: hardening agent ratio of 2: 1). As a result of examining the dispersibility of mica at this time and the bending strength of the obtained pavement material, it was confirmed that both were excellent. As a comparative example, similar tests were carried out for a case where mica powder was directly mixed by a conventional method and a case where mica was dispersed in a high-concentration mica-containing material at a ratio of 10% by weight and 70% by weight. It was also found that it was inferior to the examples.
