Embodiment Construction

[0010] Below in conjunction with embodiment the present invention is further described.

[0011] The production of the metal leather-filled paper of the present invention includes five stages of base paper production, dipping processing, primer coating, top coating and embossing.

[0012] (1) Preparation of base paper: The production of base paper is mainly to make the base paper soft. After the test, the base paper is made of 70% softwood pulp and 30% chemical fiber in the production process, which can not only ensure its good softness but also can Guarantee its high strength. Base paper weight is 100g / m 2 . Among them, 70% of the softwood pulp is made of softwood pulp fiber from Canada Kelly, and 30% of the chemical fiber is made of Japanese Sojitz chemical fiber, the purpose of which is to increase its strength and softness. In order to ensure the length of the fiber during the papermaking of the pulp, it is only deflated and not beaten. After the deflaking treatment, t...

Abstract

The invention relates to a method for producing metallic leatherette paper. The method comprises the following steps of production of base paper, impregnation processing, bottom coating, top coating and embossing, wherein the top coating adopts an air knife coating method, by which the coating for the top coating prepared from pearl essence RS611 and metallic leatherette oil KL3101 is evenly coated on the surface of the paper after the bottom coating; the weight of the pearl essence RS611 is 8 to 12 percent of the total absolute dry weight of the coating for the top coating, the coating quantity for the top coating is between 8 and 10g / m, the drying temperature is between 125 and 128 DEG C, and the speed is 30m / min; and the embossing treatment is performed, so that the metallic leatherette paper with leather feeling and metallic luster is obtained. The method has the advantages of easy production and low production cost; the surface of the metallic leatherette paper produced by the method has the leather feeling, and the metallic leatherette paper is soft and can be folded freely; moreover, the metallic leatherette paper also has the metallic feeling, beautiful luster and high quality, so that the metallic leatherette paper is water-based environment-friendly metallic leatherette paper.

Description

technical field [0001] The invention relates to a production method of leather-filled paper, in particular to a production method of metal leather-filled paper with metallic luster on the surface. Background technique [0002] We know that with the development of papermaking technology, paper occupies a very important position in the packaging industry. Packaging paper also varies with the grade of the product, and the materials used are also quite different. For example, the packaging paper for ordinary fruits, vegetables, aquatic products, etc. only uses cheap cardboard paper and gray-bottomed white board paper; household appliances and other products are generally packaged with kraft cardboard paper; The packaging paper for stationery, gold and silver jewelry, etc. is made of high-grade leather-filled paper. With the development of the times, people's requirements for leather-filled paper are getting higher and higher, and they pay more and more attention to the persona...
