Description

A kind of environmental protection paper and preparation method thereof
Technical field
The present invention relates to a kind of paper and preparation method thereof, be specifically related to a kind of environmental protection paper and preparation method thereof, belong to paper production technical field.
Background technology
Paper industry holds an important position in national economy, enters 21 century, China's paper-making industry by be one continue, the industry of stable development.Modern paper is already through becoming important industry that is capital-intensive and technology-intensive type.According to paper industry association of China, the survey showed that, and the production of China's paper and paperboard during 2009 reaches 8,640 ten thousand tons, increases nearly 8.3% than last year, and the total quantity consumed of paper and paperboard also increases nearly 8% than last year.Within 2009, increase twice nearly than production in 2000, consumption figure improves 1.4 times.But China is the country of a forest reserves critical shortage, at present, area of woods only about 1.75 hundred million hectares, afforestation rate approximately only has 18.2%.In a short time, China can not provide enough forest products resource for pulping and paper-making to paper industry.
Because paper adds paper properties such as filling out the opacity, whiteness and the printability that not only improve paper to a certain extent, and the price of fiber is general higher, and the price of filler is comparatively cheap, facilitates height and adds the trend that the amount of filling out papermaking adopted by paper-making industry.But, really there is many challenges in the consumption increasing filler, the runnability of paper machine can be affected as added higher filling adding amount, also can cause the deposition of filler in slurry and plain boiled water and keep, white water clarification difficulty, and the relevant control problem of wet end chemistry, the strength character that simultaneously result also in into paper significantly descends degradation.High loaded sheet is the paper of filer content more than 30% in paper.The too high paper strength performance that makes of filer content seriously reduces, mainly because the increase of filling adding amount reduces the adhesion between fiber and fiber, between fiber and filler.If fill out paper be coated with adding, so papermaking enterprise will be considered to adopt the less demanding coating method of paper strength, as curtain coating mode and premetering size press coating method etc., may increase the investment of capital construction cost like this.Meanwhile, paper plant also will consider selected wet end chemistry product and be equipped with good control system to deal with the various problems caused because of the increase of filling adding amount.Too high the adding of amount of filler may form uneven wadding aggressiveness in page, thus causes paper sheet formation poor; Also keeping of filler may be made lower, and slurry water filtering performance is poor.By selecting more suitable retention aid and filtering aid system and filling kind to address these problems to a certain extent, the Microparticle Retention System as comparatively paid close attention to by researcher recently not only can improve filler retention and improve paper sheet formation, also can improve slurry water filtering performance.Be applied to and add the functional pigment filled out and can produce stronger adhesion with fiber, just as the adhesion between fiber and fiber, thus reduce the impact on the strength character of paper, these pigment need paper industry to develop and are applied to production.
Chinese Patent Application No. CN201210548235.5 discloses a kind of paper, and its at least one surface is applied with the microcapsules of parcel antibacterial material, and the antibacterial material wrapped up in these microcapsules is have the volatile essential oil of antibacterial functions, natural extract or natural organic matter.Paper surface of the present invention is applied with the microcapsules of parcel antibacterial material, the diffusion that effectively prevent antibacterial material before using is run off, in use procedure, paper acts on microcapsules pressure-rupturable through wiping, rubbing, fold etc., and the antibacterial material inside microcapsules discharges and plays effective antibacterial effect.But the characteristic of this paper is antibacterial, do not have environmental protection and saving function, so it is significant to develop a kind of environmental protection paper and preparation method thereof.
