Problems solved by technology

[0004] In the existing technology, in the sizing process, in order to increase the adhesion effect of the sizing agent to the paper, aluminum sulfate is often added, but the addition of aluminum sulfate is easy to cause corrosion to the papermaking equipment, resulting in dirt, foam and other effects. The domestic paper industry is A lot of work has been done to achieve neutral and alkaline sizing, and a lot of progress has been made in the development of sizing agents, but there are still poor sizing properties, such as low adhesion rate, poor stability, and water resistance. , poor oil resistance and other issues

Abstract

The invention provides a rosin sizing agent and a preparation method thereof. The raw material formula includes components in parts by weight: 20-40 parts of cationic rosin glue; 8-12 parts of reinforced rosin glue; 5-15 parts of modified talcum powder 10-20 parts of cyclodextrin; 10-18 parts of cetyltrimethylammonium chloride; 3-6 parts of polyglycerol alkyl ether; 3-5 parts of chitosan; 3-aminopropyl trimethoxy 2-5 parts of base silane. The technical effect of the invention is: the rosin sizing agent prepared by the formula and the preparation process has a high adhesion rate, and has relatively high oil resistance and stability.

Description

technical field [0001] The invention belongs to the technical field of rosin sizing agent and preparation technology, and in particular relates to a rosin sizing agent and a preparation method. Background technique [0002] The sizing agent is divided into two categories: rosin type and non-rosin type. Rosin-type sizing agents mainly use rosin, mainly including rosin glue, reinforced rosin glue, paraffin rosin glue, and dispersed rosin glue. High free rosin gum. Non-rosin sizing agents mainly include paraffin latex, sodium stearate, polyvinyl alcohol, carboxymethyl cellulose, animal glue, casein, starch, synthetic gum, etc. Rosin type sizing agent is mainly used for internal sizing, non-rosin type sizing agent is mostly used for surface sizing, and non-rosin type sizing agent is also used as internal sizing agent for paper or cardboard with special requirements. [0003] Sizing refers to a method of treating paper or board. The purpose of paper sizing is to render the pa...
