Embodiment 1

[0015] The preparation method of this rosin sizing agent is as follows:

[0016] In the stirring state, first heat and melt 100 kg of rosin, then add 15 kg of soybean oil fatty acid, 5 kg of phosphorus oxychloride, 2 kg of sodium acetate, 8 kg of polyethylene glycol, 0.15 kg of sulfonated lignin, 20 kg of dimethyl silicon and conductivity 15kg of deionized water with rate less than 5μS / cm, then heated to 80°C, and reacted at constant temperature for 2 hours.

[0017] The rosin sizing agent prepared in this example has good stability and can be stored for 2 years at 40°C.

Embodiment 2

[0019] This rosin sizing agent comprises the following preparation steps:

[0020] In the stirring state, first heat and melt 100 kg of rosin, then add 17 kg of soybean oil fatty acid, 8 kg of phosphorus oxychloride, 1 kg of sodium acetate, 10 kg of polyethylene glycol, 0.1 kg of sulfonated lignin, 15 kg of dimethyl silicon and conductivity 12kg of deionized water with rate less than 5μS / cm, then heated to 65°C, and reacted at constant temperature for 2 hours.

[0021] The rosin sizing agent prepared in this example has good stability and can be stored for 2 years at 40°C.

Embodiment 3

[0023] This rosin sizing agent comprises the following preparation steps:

[0024] In a stirring state, first heat and melt 100 kg of rosin, then add 20 kg of soybean oil fatty acid, 6 kg of phosphorus oxychloride, 1.5 kg of sodium acetate, 6 kg of polyethylene glycol, 0.2 kg of sulfonated lignin, 25 kg of dimethyl silicon and 10kg of deionized water with a conductivity less than 5μS / cm, then heated to 60°C, and reacted at constant temperature for 1 hour.

[0025] The rosin sizing agent prepared in this example has good stability and can be stored for 2 years at 40°C.

Abstract

The invention disclosed a rosin sizing agent, belonging to the technical field of rosin deep processing. The rosin sizing agent is prepared from the following raw materials in parts by weight: 100 parts of rosin, 15-20 parts of soybean oil fatty acid, 5-8 parts of phosphoryl trichloride, 1-2 parts of sodium acetate, 6-10 parts of polyethylene glycol, 0.1-0.2 part of sulfonated lignin, 15-25 parts of dimethyl silicone oil and 10-15 parts of deionized water with conductivity less than 5mu S / cm. By adding the soybean oil fatty acid, the phosphoryl trichloride, the sodium acetate, the polyethylene glycol, the sulfonated lignin, the dimethyl silicone oil and the deionized water with conductivity less than 5mu S / cm into the rosin, the prepared rosin sizing agent has the advantage of being high in stability.

Description

technical field [0001] The invention belongs to the technical field of rosin deep processing, and in particular relates to a rosin sizing agent. Background technique [0002] Sizing agent is an additive for papermaking, it can endow paper and cardboard with properties such as ink resistance, water resistance, emulsion resistance and corrosion resistance, so as to improve its smoothness, strength and service life. Sizing agents can be divided into internal sizing agents and surface sizing agents, among which rosin sizing agent is a kind of internal sizing agent for papermaking additives. [0003] There are many kinds of rosin sizing agents sold in the market, but most of them have the defects of poor stability and short shelf life. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a rosin sizing agent, thereby solving the problems of poor stability and short shelf life of the existing rosin sizing agent.
