Abstract
The invention discloses a soft porcelain material and a preparation method thereof, wherein the soft porcelain material comprises the following raw materials: industrial waste residue, filler, polymer emulsion, photosensitive resin, silane coupling agent, reinforcing fiber, water reducer, foaming agent, waterproofing agent and water, wherein the photosensitive resin comprises photoinitiator, oligomer, reactive diluent and auxiliary additive. Firstly adding a silane coupling agent for modification, wherein the molecular structural formula of the silane coupling agent generally contains organic functional group siloxy. The siloxy groups are reactive with inorganic materials and the organic functional groups are reactive or compatible with organic materials. Therefore, when the silane coupling agent is between the inorganic interface and the organic interface, a bonding layer of an organic matrix, the silane coupling agent and the inorganic matrix can be formed, and the polymer emulsion with a bonding effect and the photosensitive resin with a photosensitive effect are added to print out the soft porcelain material with a target specification, so that the method is beneficial to large-scale production, and the produced soft porcelain material has the characteristics of flat surface, high dimensional accuracy and uniform slurry distribution.
Description
Technical Field
The invention relates to the technical field of green environmental protection, in particular to a soft porcelain material and a preparation method thereof.
Background
The forming process with the best application prospect of the current ceramic 3D printing process is a digital light processing surface exposure forming process (digital lightprocession, DLP), and the target part is manufactured by acquiring two-dimensional accumulated data of a ceramic part three-dimensional model, and irradiating the cured resin by ultraviolet light and overlapping the resin layer by layer.
However, the existing soft porcelain material has higher density, cannot meet the demand of the market for lightening soft porcelain, has complex preparation process, lower efficiency, uneven surface, poor dimensional accuracy and uneven slurry distribution, and is not suitable for mass production.
Disclosure of Invention
The invention mainly aims to provide a soft porcelain material and a preparation method thereof, which are used for solving the problems that the existing soft porcelain material is high in density, low in production efficiency and low in accuracy, and the requirements of the market on the soft porcelain material cannot be met.
In order to achieve the above purpose, the invention provides a soft porcelain material, which comprises the following raw materials: industrial waste residues, fillers, polymer emulsion, photosensitive resin, silane coupling agent, reinforcing fiber, water reducer, foaming agent, waterproofing agent and water; wherein the photosensitive resin comprises a photoinitiator, an oligomer, a reactive diluent and an auxiliary additive.
Optionally, the raw materials comprise the following components in parts by weight: 30-50 parts of industrial waste residue, 50-80 parts of filler, 20-50 parts of polymer emulsion, 30-50 parts of photosensitive resin, 1-5 parts of silane coupling agent, 1-2 parts of reinforcing fiber, 1-2 parts of water reducer, 1-2 parts of foaming agent, 1-2 parts of waterproof agent and 10-50 parts of water.
Optionally, the industrial waste residue comprises at least one of engineering waste soil, slag, coal slag and manganese slag; and/or the number of the groups of groups,
the filler comprises at least one of quartz sand and corundum sand; and/or the number of the groups of groups,
