Abstract

The invention relates to a reinforcing agent for papermaking coating, and a preparation method and an application thereof. The raw material formula of the reinforcing agent comprises, by weight, 100 parts of a biomass material, 10-80 parts of metal salt, 200-400 parts of a complexing agent, 5-50 parts of an organosilicon waterproofing agent, and water with required amount to realize solid content adjustment. The reinforcing agent using the biomass material with abundant source, low price and degradable property as the raw material is of great significance to realizing complete regeneration and recycling of coated paper products. The reinforcing agent has the advantages of excellent performances, good compatibility with the formula of a coating, safety, environmental protection and non-toxicity, and meets GB9685-2008 requirements on food packaging paper additives, and the performances of paper obtained by using the reinforcing agent are same to the performances of paper obtained by using samples in the market, ad completely accord with the use performances of the coated paper.

Description

technical field [0001] The invention relates to a novel coating enhancer which can be used in the field of coated paper in the papermaking industry or food packaging and a preparation method thereof. Background technique [0002] Coated paper is mainly used in various color printing to obtain beautifully printed, vividly colored prints. Coated paper for printing needs to have a certain degree of water resistance, and in order to achieve surface water resistance, in addition to sizing the base paper or surface sizing, the most direct way is to add a reinforcing agent to the coating to reduce the pigment. , adhesives and various water-soluble components after drying into a film, improve the nap strength, wet and dry strength and wet friction of coated paper, improve the printing adaptability of coated paper, and reduce coating during printing The phenomenon of lint and powder falling off the paper can obtain excellent printed matter. [0003] At present, the commonly used co...
