specific Embodiment 1

[0037]After dissolving 0.1 mass parts of protein-type surfactant, 0.6 mass parts of rosin-based hyperbranched surfactant B1, 3 mass parts of hydroxymethyl cellulose, and 0.5 mass parts of imidazole antifungal and fungicide into 74.3 mass parts of water, use hydrogen Sodium oxide is used as a pH value regulator to adjust the pH value of the solution to 8.0, and mix evenly; 21 parts by mass of bamboo charcoal powder are added to the mixed solution, and the bamboo charcoal slurry is obtained through dispersion, grinding, and filtration, wherein 0.5 parts by mass of polyether compound are added during the grinding process defoamer.

specific Embodiment 2

[0039] 0.2 parts by mass of protein surfactant, 0.05 part by mass of rosin-based hyperbranched surfactant B2, 1 part by mass of hydroxyethyl cellulose and 1 part by mass of hydroxypropyl methylcellulose, 0.05 part by mass of thiazoles for mildew and sterilization After the agent is dissolved in 87.5 parts by mass of water, potassium hydroxide is used as a pH regulator to adjust the pH value of the solution to 9.0, and mixed uniformly; 10 parts by mass of bamboo charcoal powder are added in the mixed solution, and the bamboo charcoal slurry is obtained through dispersion, grinding and filtration. In the grinding process, 0.05 parts by mass of polysiloxane ether copolymer and 0.15 parts by mass of polyether compound defoamer are added.

specific Embodiment 3

[0041] 0.9 parts by mass of protein surfactant, 0.6 parts by mass of rosin-based hyperbranched surfactant B3, 1 part by mass of methyl hydroxyethyl cellulose, and 0.3 parts by mass of isothiazolone derivative antifungal and fungicide are dissolved to 66.9 parts by mass After being in water, use ammonia water as a pH value regulator to adjust the pH value of the solution to 10.0, and mix evenly; 30 parts by mass of bamboo charcoal powder are added to the mixed solution, and the bamboo charcoal slurry is obtained through dispersion, grinding, and filtration, wherein 0.3 parts by mass of polycarbonate are added during the grinding process. Silicone ether copolymer defoamer.

Abstract

The invention discloses a bamboo charcoal slurry for viscose collagen solution spinning and a preparation method thereof. The bamboo charcoal slurry comprises bamboo charcoal powder, protein-type surfactant, rosin-type hyperbranched surfactant, thickener, defoamer, An antifungal and fungicide, the method uses a protein-type surfactant and a rosin-based hyperbranched surfactant with a specific structure as a dispersant, and utilizes the compounding between the two surfactants to play a synergistic effect. It is beneficial to the stable dispersion of the bamboo charcoal powder in the water-based system; the prepared bamboo charcoal slurry has excellent storage stability and spinnability, and the bamboo charcoal powder has good dispersibility in the viscose fiber spinning stock solution.

Description

technical field [0001] The invention relates to a bamboo charcoal slurry and a preparation method thereof, in particular to a bamboo charcoal slurry for viscose collagen solution spinning and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] Bamboo charcoal is a kind of material formed by treating bamboo through high-temperature drying and carbonization process. Its surface has a honeycomb microporous structure. The loose and porous structure has strong adsorption capacity, which makes bamboo charcoal itself have excellent deodorization and antibacterial properties Effect; Bamboo charcoal contains mineral components such as potassium, calcium, and sodium, and it will release negative ions when used, which can enhance human immunity; in addition, bamboo charcoal also has high conductivity and radiation resistance. The above-mentioned excellent properties of bamboo charcoal have been widely researched and applied. A...
