Embodiment 1

[0049] The weight content of the selected organic polymer, inorganic thickener, pH regulator, dispersant, defoamer, organic thickener, inorganic powder and water is also as follows:

[0050]

[0051] The production method of this embodiment is: use a disperser to disperse for 6 minutes under the condition of 300r / min, the viscosity of the slurry is 70ku, spray it on the surface of the continuous non-woven fabric, control the air pressure of the spray gun to 0.4MPa, and the material pressure to 0.4MPa , the thickness of spraying is 3mm, after spraying, irregular concave-convex shapes are formed on the surface, and it is dried in a 150°C oven for 2 hours. Dry for 5 hours, and roll up after complete drying. After the sprayed layer with a thickness of 3 mm is polished to 1 mm by a 120-mesh fine sand machine, the finish varnish is sprayed with a thickness of 80 μm. Since most of the protrusions on the surface of the sprayed coating have been flattened, while the concave parts a...

Embodiment 2

[0053] The weight content of selected organic polymer, inorganic thickener, pH regulator, dispersant, defoamer, organic thickener, inorganic powder and water is as follows:

[0054]

[0055]

[0056] The production method of this embodiment is: use a disperser to disperse for 15 minutes under the condition of 1000r / min, the viscosity of the slurry is 110ku, spray on the surface of the continuous non-woven fabric, control the air pressure of the spray gun to 0.20MPa, and the material pressure to 0.6MPa , The spraying thickness is 5mm. Due to the high viscosity of this slurry, it can form large unevenness on the surface after spraying with low air pressure. Dry through a 150°C oven for 3 hours, wind up after complete drying, and then scrape the slurry on the back of the non-woven fabric with a thickness of 2mm, dry through a 150°C oven for 3 hours, and wind up after completely drying. After the sprayed layer with a thickness of 5 mm is polished to 2 mm by an 80-mesh fine s...

Embodiment 3

[0058] The weight content of selected organic polymer, inorganic thickener, pH regulator, dispersant, defoamer, organic thickener, inorganic powder and water is as follows:

[0059]

[0060]

[0061] The production method of this embodiment is: use a disperser to disperse for 10 minutes under the condition of 700r / min, the viscosity of the slurry is 100ku, spray it on the surface of the continuous glass fiber cloth, control the air pressure of the spray gun to 0.30MPa, and the material pressure to 0.5MPa , the thickness of spraying is 4mm, dried in a 110°C oven for 3 hours, and rolled up after complete drying, and then scraped the slurry on the back of the glass fiber cloth with a thickness of 2mm, dried in a 120°C oven for 4 hours, and rolled up after complete drying. After the 4mm thick sprayed layer is polished by an 80-mesh fine sand machine for 1 mm, then lightly polished by a 120-mesh fine sand machine to about 200 μm, and the finish varnish is sprayed with a thickn...

Abstract

The invention provides a manufacturing method of a natural travertine stone imitated flexible sheet material. The manufacturing method comprises the following steps: adding an inorganic thickening agent, a pH (Potential of Hydrogen) regulator, a dispersant, a de-foaming agent, an organic thickening agent, water and inorganic powder into an organic polymer in sequence and stirring uniformly to obtain organic polymer modified inorganic powder slurry with the viscosity of 70Ku to 110Ku; taking a non-woven fabric or a glass fiber fabric as a base material and spraying the slurry on a front surface of the base material; after the slurry completely becomes dry, scraping the slurry on a back surface of the non-woven fabric or the glass fiber fabric to prepare a flexible coiled material; polishing a spraying layer on the front surface through utilizing a fine sanding machine; spraying cover varnish to prepare the natural travertine stone imitated flexible sheet material. The manufacturing method of the natural travertine stone imitated flexible sheet material, provided by the invention, has the characteristics of simple process, rapid drying speed and high production efficiency; the organic polymer is used so that the sheet material has very good flexibility; natural and irregular holes and patterns can be formed and the travertine stone imitation effect is good.

Description

technical field [0001] The invention relates to a method for manufacturing a stone-like material for construction, and belongs to the technical field of stone-like building materials, and more specifically relates to a method for making a flexible sheet imitating natural travertine. Background technique [0002] With the development of my country's construction industry, people have higher and higher requirements for the performance and decorative effects of building exterior walls. Natural stone has become people's favorite exterior wall decoration materials due to its calm and atmospheric decorative effect and excellent protection performance. Radioactive substances can easily cause hidden dangers such as radiation to the human body. With the improvement of people's awareness of environmental protection, the ecological damage and environmental pollution caused by the over-exploitation of natural stone have greatly restricted the use of natural stone. [0003] At present,...
