The existing standard UHPC curtain wall board has the decoration varieties of clear water surface, polished surface, water-milled exposed material collecting surface, sand-blasted or acid-washed exposed material collecting surface, molded or rolled concave-convex molding surface and the like, the decoration has single overall color and few varieties of colors, although the exposed material collecting surface can expose various colors of natural colored stone or colored sand, a colorful artistic pattern can not be formed, the color is selectable and the processing grinding amount is large.
Disclosure of Invention
The invention aims to solve the problems of single decoration color and few patterns and varieties of the existing standard UHPC curtain wall board, and provides a production and forming method of a colorful UHPC curtain wall board suitable for industrial application.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for producing and forming a colorful UHPC curtain wall board is characterized in that:
1. the colorful UHPC curtain wall board is made of UHPC material, the surface decoration is formed by moulding a template, distributing the fabric and physically treating the decoration layer after demoulding.
2. The production and forming steps of the colorful UHPC curtain wall board are as follows:
(1) stirring the fabric and the backing material
Respectively weighing and stirring the fabric (the UHPC material forming the decorative layer of the colorful UHPC curtain wall board) and the backing material (the UHPC material forming the structural layer of the colorful UHPC curtain wall board) according to respective formulas, and stirring the materials into high-flow-state self-compacting slurry.
(2) Spraying release agent
A layer of thin and uniform release agent is sprayed on the template, and when the water-based release agent is adopted, baking or hot air blow-drying can be adopted to shorten the film forming time of the release agent.
(3) Cloth fabric
According to the colors and the decorative patterns of the surface decoration of the colorful UHPC curtain wall board, the fabric with two or more colors is sequentially arranged on the surface of the template by adopting several mechanical devices such as elastic coating (a mechanical device which throws the fabric in a point shape by using the elasticity of a steel wire), intelligent coating (an intelligent mechanical device which can automatically arrange the fabric on the template according to the set decorative patterns) and spraying or paving to form the colorful UHPC curtain wall board decorative layer. When the fabric of the former color is disturbed by the fabric arrangement or the back material arrangement of the latter color, the fabric of the former color can be continued for a proper time at the ambient temperature of 30-40 ℃ after the fabric of the former color is arranged, so that the fabric of the former color loses or reduces the plasticity.
(4) Cloth backing material
And uniformly spreading the backing material on the fabric by adopting a spreading device according to the thickness of the colorful UHPC curtain wall plate to form a structural layer of the colorful UHPC curtain wall plate.
(5) Steam curing
And (3) stacking and conveying the templates to a steam curing room for steam curing, wherein the steam curing process comprises the steps of standing, heating, keeping constant temperature and cooling. And demolding after steam curing.
(6) Physical treatment of decorative layers
After demoulding, the decorative layer of the colorful UHPC curtain wall board is subjected to physical treatment (grinding, polishing, chiseling, sand blasting and other processing by adopting machinery) to achieve the decorative effect meeting the requirements. When the surface of the colorful UHPC curtain wall board is a clear water decorative surface, no treatment is carried out.
The invention mainly has the following beneficial effects:
1. the corresponding automatic forming equipment is designed and manufactured according to the method of the invention, and the industrial high-efficiency production of the colorful UHPC curtain wall board can be realized.
2. The invention can respectively select raw materials and formulas according to different requirements of the fabric and the backing material, and is beneficial to
The cost of production materials is reduced.
3. Compared with exposed aggregate decoration, the method for laying the fabric with the pattern patterns has the advantages that the grinding amount is much smaller, the material waste is greatly reduced, and the paper production and processing cost is reduced.
4. The colorful UHPC curtain wall board has rich color, colorful patterns and strong artistic sense, and greatly enriches the colors and the patterns of the existing standard UHPC curtain wall board.
Drawings
FIG. 1 shows a process for producing a multi-color UHPC curtain wall panel according to the present invention.
Detailed Description
Referring to fig. 1, a method for producing and forming a colorful UHPC curtain wall board,
1. the colorful UHPC curtain wall plate is made of UHPC materials, and the surface decoration is formed by three methods: adopting a template with a flat surface or a concave-convex shape on the surface; secondly, two or more than two colors of fabrics are adopted, one of the fabrics is used as a ground color, and the rest fabrics are distributed in a dot or pattern; and thirdly, performing fine grinding/fine grinding polishing/sand blasting treatment on the decorative layer after demoulding.
2. The production and forming steps of the colorful UHPC curtain wall board are as follows:
(1) stirring the fabric and the backing material
And weighing and stirring the materials according to respective formulas of the fabric and the backing material, and stirring the materials into high-flow-state self-compacting slurry.
(2) Spraying release agent
Spraying a layer of thin and uniform water-based release agent on the template, and baking by adopting infrared rays to enable the release agent to be quickly formed into a film.
(3) Cloth fabric
