Embodiment 1

[0019] Embodiment 1, unit: kg

[0020] Prepare auxiliary agents, weigh raw materials according to the ratio of 60 parts of polyethylene glycol, 30 parts of propylene glycol, 5 parts of glycerin, 3 parts of isohexadecane, 1.5 parts of triethanolamine, and 0.5 parts of N,N-dimethylformamide , Add it to the mixing tank at room temperature, stir well and put it into the barrel evenly. Take 11kg of mixed additives, 750kg of sodium alginate, 40kg of sodium hexametaphosphate, 209kg of anhydrous sodium sulfate, and 1kg of preservatives, stir and mix them at room temperature, and place them at room temperature for 9 months. Compared with them, the appearance does not change significantly. There was no increase in the amount of product dust and no change in dispersibility in water.

Embodiment 2

[0021] Embodiment 2, unit: kg

[0022] Preparation of auxiliary agents, weighing raw materials according to the ratio of 53 parts of polyethylene glycol, 30 parts of propylene glycol, 10 parts of glycerin, 5 parts of isohexadecane, 1 part of triethanolamine, and 1 part of N,N-dimethylformamide , Add it to the mixing tank at room temperature, stir well and put it into the barrel evenly. Take 12kg of mixed additives, 600kg of sodium alginate, 50kg of sodium hexametaphosphate, 348kg of anhydrous sodium sulfate, and 2kg of preservatives, stir and mix at room temperature before use.

Embodiment 3

[0023] Embodiment 3, unit: kg

[0024] Prepare auxiliary agents, weigh raw materials according to the ratio of 60 parts of polyethylene glycol, 30 parts of propylene glycol, 5 parts of glycerin, 3 parts of isohexadecane, 1.5 parts of triethanolamine, and 0.5 parts of N,N-dimethylformamide , Add it to the mixing tank at room temperature, stir well and put it into the barrel evenly. Take 800kg of sodium alginate, 60kg of sodium hexametaphosphate, 139kg of anhydrous sodium sulfate, and 1kg of preservative, mix them evenly at room temperature, and divide them into two equal portions. Add 6kg of mixed additives to one part, and the other as a blank control to compare its use and dissolution. The results show that the dust content of the printing paste after adding the additives is significantly reduced, the mixture is more uniform, and its dispersibility in water is better without obvious clumping phenomenon.

Abstract

The invention provides an additive of printing paste as well as a preparation method and a using method of the additive. The additive can be used for solving the problems in the prior art that dust flying exists, a product is easy to aggregate during dissolution and cannot be fully dissolved, and a stirring mixed material has relatively poor uniformity. Polyethylene glycol, propylene glycol, glycerin and triethanolamine in the additive have certain viscosity, can be mixed and dissolved in water, but cannot dissolve sodium alginate, and therefore, after the additive is added, the additive cannot damage the viscosity of the printing paste, also does not enable the sodium alginate to aggregate due to swelling and is beneficial to the improvement of the dispersibility of the sodium alginate in water. The additive has certain moisture absorption and is adhered to the surfaces of particles, and the tiny particles are spliced together through the additive, so that the dust flying is avoided, and the uniformity of the mixed material is improved.

Description

technical field [0001] The invention relates to an auxiliary agent for sodium alginate printing paste, a preparation method and a use method. Background technique [0002] Sodium alginate is used in printing paste, and it is generally ground into 30-mesh powder. The current milling technology makes the particle size distribution of the product uneven, and often produces a large amount of high-mesh powder. For example, the pass rate of 120 mesh in ordinary 30 mesh sodium alginate can reach more than 10%. The existence of this part of the fine powder brings many disadvantages. In the production process, it will cause dust to fly, which will not only pollute the environment, affect the health of employees, but also reduce the product yield and increase costs; in the use process, it is also because the dust affects the environment and health, and it will cause the product to clump easily when it dissolves. Insufficient dissolution leads to network blocking. In addition, there...
