Embodiment Construction

[0034] In order to make the technical solutions of the present invention clearer and clearer to those skilled in the art, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0035] Such as figure 1 As shown, a kind of production method with waterproof characteristic pulp provided by the present embodiment, described method comprises the following steps:

[0036] Step S1: Raw material selection

[0037] The raw material is recycled waste paper, and the recycled waste paper is shredded;

[0038] Step S2: Squeeze, Soak

[0039] Put the shredded waste paper into the extruder, or crush the shredded waste paper into shredded paper; put the squeezed or crushed waste paper into the soaking tank, add water and stir evenly, so that the shredded paper becomes paste stop;

[0040] Step S3: Cooking and sterilization, removal of impurities

Abstract

The invention discloses a production method of paper pulp with waterproofness, and belongs to the technical field of paper pulp production. The method includes the following steps of raw material selection, extrusion, soaking, cooking sterilization, impurity removal, preparation of a paper pulp semi-finished product, preparation of a filament blank, preparation of ground paper, preparation of a paper pulp finished product, and waterproofness testing. According to the method, a new technology is adopted to make the waterproof paper pulp, it can be avoided that an additional procedure is needed in carton processing, a composite dampproof adhesive and YF-921 cationic starch are added directly in the paper pulp processing process to form the waterproof paper pulp, the outward processing of waterproof layer coating is not needed in the midway of the carton manufacturing process, the procedures are simplified, and the cost is reduced; according to the paper pulp produced through the method, the outward processing of waterproof layer coating is not needed, it is only needed to make the waterproof paper pulp with the needed model and specification, and corresponding waterproof cartons can be made as needed; the waterproof capability of the paper pulp is effectively improved.

Description

technical field [0001] The invention relates to a production method of paper pulp, in particular to a production method of paper pulp with waterproof properties, and belongs to the technical field of paper pulp production. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods. It can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp according to the processing method, and can also be divided into wood pulp, straw pulp and hemp pulp according to the fiber raw materials used. pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc., and can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. according to different purity; generally used to make paper and cardboard In addition to being used for the manufacture of specialty paper, refined pulp is also often used as a raw material for the manufacture of cellulose derivatives such as cel...
