Embodiment 1

[0040] The production method of white fine kraft grain flame-retardant leather-filled paper comprises the following steps:

[0041] (1) Production of base paper, base paper basis weight 85g / m 2 , Slurry ratio: softwood pulp 70% (total dry fiber content), chemical fiber 30% (total dry fiber content), wet strength agent PAE 2.5% (wet strength agent stock solution to total dry fiber content ). The coniferous wood pulp is Canadian Kelly Pu softwood pulp, the chemical fiber is 4mm short fiber produced by Japan Sojitz Corporation, and the PAE is the product of Shandong Zibo Jinli Chemical Co., Ltd. Slurry treatment only defrosts, without beating, to ensure that the fibers are not damaged and the length of the fibers is not lost. Produced by 1760mm fourdrinier multi-cylinder paper machine, the surface absorption weight of the produced base paper is 250-280g / m 2 , The paper machine production speed is 160m / min.

Embodiment 2

[0048] The production method of red certificate pattern flame-retardant leather-filled paper comprises the following steps:

[0049] (1) Production of base paper, base paper basis weight 100g / m 2 , Slurry ratio: softwood pulp 70% (total dry fiber content), chemical fiber 30% (total dry fiber content), wet strength agent PAE 2.5% (wet strength agent stock solution to total dry fiber content ). The coniferous wood pulp is Canadian Kelly Pu softwood pulp, the chemical fiber is 4mm short fiber produced by Japan Sojitz Corporation, and the PAE is the product of Shandong Zibo Jinli Chemical Co., Ltd. Slurry treatment only defrosts, without beating, to ensure that the fibers are not damaged and the length of the fibers is not lost. Produced by 1760mm fourdrinier multi-cylinder paper machine, the surface absorption weight of the produced base paper is 250-280g / m 2 , The paper machine production speed is 160m / min.

Embodiment 3

[0056] The difference between the test conditions of this example and Example 1 is: between steps (2) and (3), it also includes calendering and finishing the paper obtained in step 2 through a light press, wherein the pressure is 8MPa, The vehicle speed is 50m / min, and the pressurization temperature is room temperature (20 degrees Celsius). The weight per square meter of the finally obtained leather filled paper was 142 grams. In this test, it was found that the amount of latex used was significantly lower than that of Example 1, and the adsorption amount of latex decreased significantly, and the impregnation amount was 14.6 g per square meter. The pressurization process is realized on the paper roll by extrusion with a special ring extrusion die.

Abstract

The invention discloses leatherette paper with a flame-retardant function and a production method of the leatherette paper. The production method comprises the following steps that (1) raw paper is provided; (2) a flame retardant is applied to the paper in the step 1 and dried, and the flame retardant of the paper is applied in the mode of a water-soluble ammonium polyphosphate flame retardant solution; (3) paper obtained in the step 2 is dipped in latex, and the redundant latex on the surface of the paper is scraped through a scraper; and (4) paper obtained in the step 3 is subjected to bottom layer coating, surface layer coating and embossing treatment. The leatherette paper has the good flame-retardant function and has the good moisture absorption resisting property, and after the leatherette paper is wetted and redried, the obvious fold and property changing phenomena of the leatherette paper are avoided. The leatherette paper can be used for high-grade packing materials because ofthe characteristics of the leatherette paper.

Description

technical field [0001] The invention relates to a paper impregnating material, which is characterized by its function, especially a leather-filled paper with flame-retardant function and its production method. Background technique [0002] As a high-grade packaging paper, leather-filled paper has been accepted by people and is widely used in the packaging of various products, such as jewelry, cosmetics, wine, stationery, leather goods, clothing and other products. Ordinary leather-filled paper is formed by dipping and dyeing base paper, dipping latex, primer, top coating, embossing and other processes. Although it has a leather-like luster and texture from the surface effect, its essence is still made of plant fiber raw materials and latex, The paper products formed by the combination of pigments, so the leather-filled paper is easy to burn after encountering an open flame, and its safety performance is poor. Contents of the invention [0003] In order to overcome the dis...
