Embodiment 1

[0015] The basis weight of the base paper for the production of environmentally friendly paper leather base paper is 80g / m 2 . The base paper of leather paper adopts 100% fiber raw materials, and the selected fiber raw materials and weight ratio are 45% of coniferous pulp and 55% of cotton pulp. Compared with the base paper of other ordinary leather-filled papers, great adjustments have been made in the fiber ratio. A large proportion of cotton pulp is used in the pulp ratio of the paper leather base paper to improve the tearing and folding resistance of the base paper. In order to ensure the length of the fiber during the papermaking of the pulp, it is only deflated and not beaten. After deflaking treatment, the degree of percussion of pulp is 20-22°SR, the concentration of pulp on the net is 0.05%, and the basis weight of base paper is 80g / m 2 , bulk thickness 2.5cm 3 / g, surface absorption weight 320g / m 2 . The paper is made by using a 1600mm inclined wire paper machin...

Embodiment 2

[0026] The production of environmentally friendly paper leather base paper The quantitative of the base paper is 100g / m 2 . The paper leather base paper adopts 100% fiber raw materials, and the selected fiber raw materials and weight ratio are 50% of coniferous pulp and 50% of cotton pulp. Compared with the bottom paper of other ordinary leather-filled papers, a great adjustment has been made in the fiber ratio. A large proportion of cotton pulp is used in the pulp ratio of the paper leather base paper to improve the tearing and folding resistance of the base paper. . In order to ensure the length of the fiber, the pulp is only deflated and not beaten during papermaking. After deflaking treatment, the degree of pulp beating is 20-22°SR, the concentration of pulp is 0.05%, and the basis weight of base paper is 100g / m 2 , bulk thickness 2.5cm 3 / g, surface absorption weight 320g / m 2 . The paper is made by using a 1600mm inclined wire paper machine. Mainly control the quan...

Abstract

The invention relates to a method for producing environment-friendly leatheroid, which adopts 100% of fiber material to produce base paper; according to the weight proportion, the selected fiber material comprises 45-55% of softwood pulp and 55-45% of cotton pulp; the method for producing the base paper comprises the following steps of: untwining of a pulp board, burdening, conveying of pulp, forming in a head box, drying and dehydrating, and coiling by coil; subsequently, the environment-friendly leatheroid is prepared by the following steps: the base paper is sequentially dipped and dyed, dipped in rubber latex, coated by primer and surface paint and pattern-pressed. The environment-friendly leatehroid has outstanding tearing resistance and folding resistance, and good soft performance, can be degraded, and is suitable for preparing covers of all certificates and hardcover, packages of exquisite gifts such as gold and silver caskets, stationery, watches and the like. The method has reasonable machining process, easy preparation, and low production cost and protects the environment.

Description

technical field [0001] The invention relates to a production process of special paper, in particular to a production method of environmentally friendly paper leather which is degradable and has the performance of tear resistance and folding resistance like leather. Background technique [0002] With the continuous development of my country's economy, paper has been widely used in many fields such as publishing and printing, packaging and decoration, application industry, information media, etc. my country's per capita paper consumption is in a leading position among developing countries. With the continuous improvement of people's consumption awareness, the requirements for product packaging are getting higher and higher, and the packaging should be beautiful, high-grade and tasteful. In this case, leather-filled paper is also widely used in the packaging of high-end products. [0003] Ordinary leather-filled paper is made of base paper and treated with primer to make it me...
