Description
Technical Field
The invention relates to the technical field of artificial stones, in particular to a preparation method of a high-strength acrylic solid plane material.
Background
The acrylic solid plane material belongs to an acrylic artificial stone and is mainly prepared by mixing and curing acrylic resin, colored or transparent particles, aluminum hydroxide powder, pigment paste and the like. The production process includes dissolving polymethyl methacrylate resin in methyl methacrylate monomer to produce acrylate resin, or pre-polymerizing methyl methacrylate monomer to produce acrylic resin with certain solid content, dispersing and mixing acrylic resin, aluminum hydroxide powder, color grains or transparent grains and color paste, adding cured initiator and promoter and forming solid acrylic plane material at normal temperature.
Aluminum hydroxide is a basic raw material for ensuring the flame retardancy of the solid plane material, but the direct bonding force between the acrylic resin and the aluminum hydroxide is very low, so that the impact strength, the tensile strength and the bending strength of the generated solid plane material are low. In addition, the added pigment is difficult to permeate into the aluminum hydroxide powder at normal temperature, and the pigment and the aluminum hydroxide powder are difficult to combine, so that the surface of the solid surface material is easy to scratch and whiten. At present, after the pigment powder is used for treating the aluminum hydroxide powder at high temperature, although the scratch resistance of the solid plane material can be improved, the aluminum hydroxide powder treated by the pigment powder has high oil absorption rate, so that the mixed slurry can reach the flow processability of a cast plate only by needing high resin amount, and the cost of the solid plane material is obviously increased.

Detailed Description
The invention is further illustrated by the following examples. These examples are intended to illustrate the invention and are not intended to limit the scope of the invention. Experimental procedures without specific conditions noted in the following examples, generally according to conditions conventional in the art or as recommended by the manufacturer; the raw materials, reagents and the like used are, unless otherwise specified, those commercially available from the conventional markets and the like. Any insubstantial changes and substitutions made by those skilled in the art based on the present invention are intended to be covered by the claims.
The preparation process of the high-strength acrylic solid plane material of each embodiment of the invention comprises the following steps:
putting aluminum hydroxide powder and pigment powder into a mixing kettle, and shearing and mixing at high speed in a heating environment to combine the aluminum hydroxide powder and the pigment powder; in the step, the aluminum hydroxide powder and the pigment powder are sheared and mixed at a high speed by a high-speed mixing stirring paddle in a mixing kettle, and meanwhile, the temperature of the mixing kettle is raised to generate high-energy collision and association action, so that the superfine pigment can penetrate into the aluminum hydroxide powder and can be combined in a chemical bonding or association mode, and the scratch-resistant whitening performance of the acrylic solid plane material is improved.
And then adding a surfactant or a coupling agent to carry out surface modification on the aluminum hydroxide powder combined with the pigment powder.
Wherein the surfactant is sodium dodecyl benzene sulfonate, sodium stearate or silicone oil, and the mechanism of modifying the surface of the aluminum hydroxide powder by using the surfactant is as follows: the polar group at one end of the molecule of the surfactant and the inorganic material are subjected to chemical reaction or physical adsorption, so that the aluminum hydroxide powder combined with the pigment powder is coated on the surface of the surfactant, the other end of the molecule is long-chain alkyl, and the long-chain alkyl and the polymer have similar structures, so that the surfactant and the acrylic resin are well compatible, and the combination of the aluminum hydroxide powder, the color particles and the acrylic resin is realized.
The coupling agent is a silane coupling agent, a titanate coupling agent or an aluminate coupling agent, and the mechanism of modifying the surface of the aluminum hydroxide powder by using the coupling agent is as follows: part of functional groups in the molecules of the coupling agent are chemically combined with aluminum hydroxide, and the other part of functional groups are bonded with the high polymer material in a carbon chain manner, so that the inorganic material is tightly connected with the organic high polymer material, namely, the aluminum hydroxide powder, the color particles and the acrylic resin are tightly connected.
Preferably, the coupling agent is a silane coupling agent. Suitable coupling agents include, among others: vinyltriethoxysilane, vinyltrimethoxysilane, vinyltris (2-methoxyethoxy) silane, vinyltrimethoxysilane oligomers, gamma-methacryloxypropyltrimethoxysilane.
After the aluminum hydroxide powder is combined with the pigment powder, the surface has high oil absorption rate, which is not beneficial to mixing with acrylic resin and generates high solid plane material castable viscosity, so that the flowability of the castable is poor and the casting process is not beneficial.
The surface modification of the aluminum hydroxide powder combined with the pigment powder is carried out by the surfactant or the coupling agent in a dry modification mode, specifically, the surfactant or the coupling agent is sprayed into a mixing kettle in a spraying mode and is stirred and mixed in the mixing kettle.
