Problems solved by technology

Although it has been proved by experiments that its color fixing performance is close to that of Japanese dyed soil, and the three additives have been proved to be non-toxic and harmless to the skin through experiments on white mice, but they have not reduced the amount of dyed soil and reduced the degree of dust pollution.
Moreover, the use of organic complexes makes it difficult to promote, and there is no report on the large-scale use of this dyed soil.

Embodiment 1

[0029] The content of each component in the slurry (mass percentage):

[0030] Polyvinyl acetate: 15%;

[0031] TiO 2 (average particle size 0.5μm): 4%;

[0032] Dyeing additive (phthalocyanine green, average particle size 0.2μm): 2%;

[0033] Water: balance.

[0034] Add the above components into water in turn while stirring mechanically in proportion to prepare 2kg of slurry, and use electrostatic spraying method to coat the surface of rush mat that has been dyed and fixed with soil, and then enter the hot air drying tunnel. Cured at 80°C for 6 minutes. During the coating process, the slurry in the tank should not stop stirring to ensure the uniformity and stability of the slurry. Before spraying, the surface of rush mat has a light green color and poor color consistency. After spraying and curing, the mat has good uniformity and full color.

Embodiment 2

[0036] The content of each component in the slurry (mass percentage):

[0037] Polyvinyl acetate: 16%;

[0038] TiO 2 : 3% (average particle size 0.9μm);

[0039] Dyeing additive (phthalocyanine green, average particle size 0.5μm): 1%,

[0040] Water: balance.

[0041] Add the above components to water in turn while stirring mechanically in proportion to prepare 5kg of paint, and use the method of electrostatic spraying to paint on the surface of rush grass mat that has been dyed and fixed with soil, and then enter the drying tunnel at 85°C Cured for 5 minutes. During the painting process, the paint in the bucket should not stop stirring to ensure the uniformity of the paint. Before spraying, the surface of the rush mat has a slightly lighter green color and poor gloss. After the above slurry is sprayed and cured, the apparent color of the mat is uniform and full, which improves the apparent color quality of the rush mat.

Embodiment 3

[0043] The content of each component in the slurry (mass percentage):

[0044] Polyvinyl acetate: 18%;

[0045] TiO 2 : 2% (average particle size 0.6μm);

[0046]Dyeing additive (chlorophyll): 0.1%,

[0047] Water: balance.

[0048] Add the above components to water in turn while stirring mechanically in proportion to prepare 5kg of paint, and use the method of electrostatic spraying to paint on the surface of rush grass mat that has been dyed and fixed with soil, and then enter the drying tunnel at 85°C Cured for 5 minutes. During the painting process, the paint in the bucket should not stop stirring to ensure the uniformity of the paint. Before spraying, the surface of the rush mat has a slightly lighter green color and poor gloss. After the above slurry is sprayed and cured, the apparent color of the mat is uniform and full, which improves the apparent color quality of the rush mat.

Abstract

The invention relates to a surface color-fixing dye for mat rush products. The surface color-fixing dye is characterized by comprising the following components in percentage by weight: 12%-18% of polyvinyl acetate, 2%-5% of TiO2, 0.1%-3% of dyeing additives and the balance of water. The invention further discloses a preparation method and a color-fixing method of the color-fixing dye. Compared with the prior art, the invention has the advantages that: the color and luster of the mat rush products after dyeing treatment can be better and fuller, the adjustment of color depth is more convenient, and the retention time of the apparent color of the mat rush products is also more lasting. Furthermore, slurry used by the surface color-fixing dye is of water-based slurry, the surface color-fixing dye has no toxicity and no volatilization of harmful gas, and the used additives are harmless to skin of human bodies, thus the surface color-fixing dye is in line with green and environment-friendly requirements.

Description

technical field [0001] The invention relates to a dye applied to rush products, and also relates to a preparation method and a color-fixing method of the color-fixing dye. Background technique [0002] Rush (rush grass) has been cultivated and processed in my country for more than 2,000 years. It is a traditional economic specialty in Jiangsu and Zhejiang. At present, the perennial planting area in Zhejiang Province is about 180,000 mu. Rush products include tatami mats, upper covering mats, jacquard mats and other small objects, which are mainly exported to the Japanese market. Japan currently has an annual demand of about 20 million tatami mats and about 9.5 million mats, 90% of which are imported from China. Ningbo City is the "Hometown of Chinese Rush", "China's Straw Weaving Base", and "China's Rush Grassland Origin". The export share accounts for 90% of the country. Due to the development of rush production and the formation of industries, it has played a very import...
