A kind of super-strength glassine base paper and its production process

Abstract

The invention discloses an ultrahigh strength glassine base paper and a production technology thereof. The production technology comprises the following steps: selecting Shanxi white bark pine, Linyi 3-5 year fast-growing triploid poplar, compounded chopped polyester fiber and alkali-free glass fiber as production raw materials; preparing the white bark pine, poplar, chopped polyester fiber and glass fiber into pulp; and preparing the pulp, making paper and lastly forming the paper. According to the production technology for the ultrahigh strength glassine base paper disclosed by the invention, the domestic white bark pine and poplar which are conveniently pulped and high in pulp yield and the chopped polyester fiber and glass fiber which can greatly promote the toughness, strength and rigidity of the end product of the paper are selected as the raw materials and the processes, such as, optimizing the pulp, preparing the pulp, making paper and post-processing, are performed, so that the physical properties of the glassine base paper are obviously promoted, the defect of easiness in breaking and cracking of the glassine in the use process of the product acquired by adopting the traditional raw materials and method can be overcome and the ultrahigh strength glassine base paper has excellent end-product paper properties and market value.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a super-strength glassine base paper and a production process thereof. Background technique [0002] As an important basic raw material industry closely related to the development of the national economy and the construction of human civilization, the paper industry is widely used in various fields such as printing, packaging, building materials, and daily use. However, with the gradual saturation of cultural paper and packaging paper in the domestic and international markets, specialty paper has become increasingly prominent as a new growth point. However, for a long time, domestic specialty paper has always been synonymous with poor quality. Since the "Thirteenth Five-Year Plan", governments at all levels have paid special attention to the paper industry, especially the field of special paper, and domestic special paper segments and market segments have gradually formed, a...

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of ultra-strength glassine base paper and its production process in order to overcome the lack of flexibility, strength and rigidity of glassine base paper in the prior art, and the production cost is high. Domestic white bark pine and poplar with high pulp rate, polyester staple fiber and glass fiber that can greatly improve the toughness, strength and rigidity of paper are used as raw materials, and by optimizing the processes of stock preparation, stock preparation, papermaking and post-treatment, Significantly improved the physical properties of glassine base paper, and solved the problem of glassine paper being fragile and fragile during the use of products obtained by traditional raw materials and methods. It has excellent paper-forming performance and market value
