Embodiment Construction

[0010] In the following, the present invention will be further described in conjunction with embodiments.

[0011] The production of the metal-filled leather paper of the present invention includes five stages: 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. According to the test, 70% softwood pulp and 30% chemical fiber are used in the production process of base paper, which can ensure its good softness and performance. Ensure its high strength. The basis weight of the base paper is 100g / m 2 . Among them, 70% of the softwood pulp is made of Canadian Kailip softwood pulp fiber raw materials, and 30% of the chemical fibers are made of Japanese Sojitz chemical fiber, which aims to increase its strength and flexibility. In order to ensure the length of the fiber during papermaking, the slurry is only deflated and not beating. After the d...

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<2>, 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 themethod 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 method for producing leather-filled paper, in particular to a method for producing 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. With the different grades of products, the materials used for packaging paper 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; high-end underwear and clothing are packaged with white board paper; watches, The packaging paper for stationery, gold and silver jewelry, etc. uses high-grade leather-filled paper. With the development of the times, people's requirements for leather-filled paper are getting higher ...
