Problems solved by technology

[0003] Paper straws are often used in beverages, but the existing straw papers still have many disadvantages when used. For example, when drinking hot drinks, the paper straws are easily softened and even deformed because they are soaked in drinks for a long time. Even loose pipes and other phenomena, for this reason, we propose an automatic disconnection mechanism for non-standard conveying equipment to solve the above problems

Abstract

The invention discloses a modification method of straw paper, and particularly relates to the technical field of straw paper, and the modification method specifically comprises the following steps: step 10, raw material preparation; step 20, wood pulp modification; step 30, cellulose modification; step 40, slurry mixing; and step 50, papermaking. The solution formed by mixed wood pulp is filled with nanoscale cellulose, the nanoscale cellulose is modified, organic groups on the cellulose are released, and the nanoscale cellulose is combined with wood fibers so that the originally disordered wood fibers form a layered net structure, the temperature tolerance is realized through free organic groups on the nanoscale cellulose, and the direct contact between water molecules and the wood fibers is further reduced, and thus the softening time of the modified straw paper is prolonged.

Description

technical field [0001] The invention relates to the technical field of straw paper, more specifically, the invention relates to a method for modifying straw paper. Background technique [0002] A straw, sometimes called a drinking straw, is a cylindrical and hollow product whose main function is to drink the beverage in the cup, and also to suck the bone marrow of some cooked animal long bones. With the enhancement of modern people's awareness of environmental protection, the straws in drinks are gradually replaced by paper products from traditional plastic products. Therefore, the types of straw paper are gradually increasing. [0003] Paper straws are often used in beverages, but the existing straw papers still have many disadvantages when used. For example, when drinking hot drinks, the paper straws are easily softened and even deformed because they are soaked in drinks for a long time. Even loose pipes and other phenomena, for this reason, we propose a non-standard conv...
