Problems solved by technology

At present, in the process of producing paper with wet strength performance, permanent wet strength agents such as melamine-formaldehyde resin, urea-formaldehyde resin and polyamide epichlorohydrin are generally used to keep the paper with good wet strength performance. The strength agent has a good effect in maintaining the wet strength

Example Embodiment

[0010] The embodiment of the present invention provides a wet strength agent, which is mainly composed of a permanent wet strength agent and a temporary wet strength agent, wherein the mass ratio of the permanent wet strength agent to the temporary wet strength agent is in the range 0.02~0.5: 0.2~5.

[0011] As is well known to those skilled in the art, the general basis for determining the permanent wet-strength agent and temporary wet-strength agent involved in the present invention is: compared with the initial wet strength of the paper after wetting, the paper is wetted 10 After seconds to 2 hours, the wet strength agent that loses less than 20% of the wet strength of the paper is a permanent wet strength agent. After the paper is wet for 10 seconds to 2 hours, the wet strength loss of the paper is greater than or equal to 50%. The strength agent is a temporary wet strength agent.

[0012] The permanent wet strength agent mainly includes urea formaldehyde resin (UF wet strengt...

Abstract

The invention relates to a wet strength agent which is mainly prepared by compounding a permanent wet strength agent and a temporary wet strength agent. The invention also relates to a paper production technology using the wet strength agent and paper manufactured by the paper production technology. Compared with the prior art, the the wet strength agent, the paper production technology and the paper have the advantages that the difference in increasing paper wet strength performance between the permanent wet strength agent and the temporary wet strength agent is skillfully used, and a certain quantity of temporary wet strength agent is added to replace partial permanent wet strength agent so that the manufactured paper can guarantee good wet strength in a using process and is easy to decompose and recover.

Description

technical field [0001] The invention relates to a wet strength agent, a paper production process and paper, in particular to a wet strength agent, a paper production process and paper capable of making the paper not only have wet strength but also have good water solubility. Background technique [0002] At present, with the improvement of people's living standards, people's demand for household paper has begun to show a multi-functional trend. For example, some types of paper require high wet strength, and they also hope that they can be quickly dissolved and printed after use. It can be quickly and easily broken up or dissolved when it is recycled as broken paper. [0003] But at present, there is no paper product that can have wet strength performance and easy decomposition performance at the same time. The reason is mainly related to the current production process of wet strength paper. At present, in the process of producing paper with wet strength performance, perman...
