摘 要：近幾年，由于中國經(jīng)濟(jì)的快速增長為造紙工業(yè)的發(fā)展提供了新的機(jī)遇與發(fā)展空間，我國紙業(yè)取得了長足的進(jìn)步，紙張?jiān)诟餍懈鳂I(yè)應(yīng)用范圍不斷擴(kuò)大。但是與國外同行相比，我國大多造紙企業(yè)相對而言較為落后，經(jīng)濟(jì)效益不佳，傳統(tǒng)產(chǎn)品的市場競爭十分激烈，而適用于新領(lǐng)域中的特殊紙種，往往給企業(yè)帶來可觀的效益，因此許多造紙企業(yè)在生產(chǎn)文化用紙、包裝用紙等常規(guī)大需求量的品種的同時(shí)，開始注重生產(chǎn)高附加值的工業(yè)用紙、特種用紙等紙種，裝飾原紙作為其中的代表正逐漸受到造紙企業(yè)的青睞。濕強(qiáng)度對于要用來印刷的裝飾原紙來說，是一個(gè)重要的特性指標(biāo)。濕強(qiáng)劑屬于功能性添加劑，大多數(shù)是抗水解的合成樹脂，在紙成形前加入到紙漿中，不僅可以提高濕強(qiáng)度，也可以給高速紙機(jī)的操作創(chuàng)造有利條件。
 本論文主要介紹了現(xiàn)在應(yīng)用最廣泛的濕強(qiáng)劑—聚酰胺聚胺環(huán)氧氯丙烷樹脂（PAE樹脂）的加入量對紙張濕強(qiáng)度的影響以及加過濕強(qiáng)劑的裝飾原紙加入不同化學(xué)藥品再制漿的研究。

The research for Increasing Wet Strength and Re-pulping Technology of Decorative base paper

 Abstract: In recent years, due to Chinese rapid economic growth for the paper industry for the development of new opportunities and development space, Chinese paper industry has made considerable progress in all walks of life in paper applications continue to grow. But compared with foreign counterparts, Chinese paper-making enterprises, most relatively backward and poor economic efficiency, the traditional market is extremely competitive, and apply to new areas of special types of paper, often to the business will generate substantial benefits So many paper-making enterprises in the production of cultural paper, packaging paper, and other big demand for conventional varieties at the same time, began to pay attention to the production of high value-added of industrial paper, special paper, and other kinds of paper, decorative base paper as one of the representatives are Gradually by paper-making enterprises of all ages. Wet strength to be used for the decorative printing paper, it is an important indicator of the properties. Wet Strength Agent additives are functional, most of whom are anti-hydrolysis of synthetic resin, before forming the paper into pulp, not only can improve the wet strength, high-speed paper machine can also create favorable conditions for the operation.
 This paper introduced the now the most widely used wet-strength agent - polyamide polyamine epichlorohydrin resin (PAE resin) addition on the strength of wet paper and wet strength agent added over the decorative paper with different chemicals Study re-pulping.
