Technical field
The invention belongs to chemical technology field is and in particular to a kind of U.S. line paper carboxylic styrene butadiene latex and preparation method thereof.
Background technology
On the U.S. line paper market of today, still most of need from the U.S., Canada, Italy, Japanese import, particularly
High temperature U.S. line paper is still completely dependent on import.Trace it to its cause and have two：One is the difficult problem in paper making itself and process technology,
Show the aspects such as papermaking process, auxiliary agent, wrinkling, dipping, rear processing, including some copy paper wet end adjuvants, impregnating agent, antiseized every
Entirely lean on import from products such as agent, this causes the attention of our papermakers；Two are because that the key producing U.S. line paper self-adhesive tape is owed
Lack, textured paper tape dependence on import always, just start oneself coating in recent years and produce textured paper tape, but be limited only to
Common grade, remains a need for the substantial amounts of special kinds of import every year, and the development of high temperature resistant textured paper tape is just just opened at home
Begin.Just because of U.S. line paper self-adhesive tape from principal yield less, the market demand as the U.S. line paper of raw material is not very vigorous,
But the continuous increase with output in domestic, the enriching constantly of product purpose, the demand of U.S. line paper also will be increasing.

Coating is attractive in appearance：Do not have obvious coating spot, no striped, do not splash, do not increase colloid.Production efficiency is high：Can be in height
Speed is lower to be coated with, not to pollute back flow roll, do not pollute felt wrapped roll.Paint adhesion is strong.Coating paper is elegant in appearance：There is whiteness height, body paper
The characteristic such as gloss, print gloss are good, flatness is good.
Printing stage：Printing adaptability is excellent：Coating layer does not fall off, surface strength high, and printing efficiency is high, can improve printing
Speed, does not produce and scalds bubble, can overlap immediately.Ink absorption, anchorage are excellent, and gas permeability, anti-foaming property are permissible while raising
Reach good balance.Curing ink excellent performance, it is speckless, printed matter is specious；
Today, due to its excellent performance and economy, carboxylic styrene butadiene latex is widely used by paper industry.It is characterized in：
High solids content and low viscosity are it is easy to upper machine runs；Caking property is strong, gives paper high tensile strength；Soft and do not stick, give paper
