preparation example Construction

[0026] The embodiment of the present invention also provides a preparation method of an antistatic treatment agent, which mainly includes the following steps:

[0027] First, the graphite oxide is ultrasonically treated. Since a large number of oxygen-containing functional groups (such as hydroxyl and carboxyl) are inserted between the graphite oxide layers, the graphite oxide after ultrasonic treatment is easily peeled off, so that the graphite oxide is exfoliated into graphene oxide. Therefore, graphite oxide has the same chemical composition as graphene oxide, but the thickness of graphene oxide is smaller than that of graphite oxide. Therefore, graphene oxide has better electrical conductivity than graphite oxide. Of course, graphene oxide can also be purchased directly.

[0028] Then, the graphene oxide and the polymer polyol are added into the reaction kettle for stirring and mixing, and the stirring and mixing is carried out at 45-55°C. During this period, hydrophilic...

Abstract

The invention provides an antistatic treating agent and a preparation method thereof, and relates to the technical field of material preparation. Raw materials of the antistatic treating agent comprise the following components in parts by weight: 20-30 parts of polymer polyol, 5-22 parts of polyisocyanate and 0.1-1 part of a conductive agent, wherein various commonly used diols are mainly adopted as the polymer polyol, the polyisocyanate includes one or both of diisocyanate and triisocyanate, and the conductive agent comprises graphite oxide and / or graphene oxide. Isocyanate groups on the polyisocyanate can react with hydroxyl groups on the graphite oxide or graphene oxide, and the isocyanate groups can also react with hydroxyl groups of the polymer polyol simultaneously. Therefore, the graphite oxide is linked into a molecular chain of polyurethane by taking the polyisocyanate as a bridge, thereby fundamentally solving the problems of aggregation and sedimentation of the graphite oxide in polyurethane resin, and enhancing the antistatic capability of a surface of polyurethane synthetic leather.

Description

technical field [0001] The invention relates to the technical field of material preparation, in particular to an antistatic treatment agent and a preparation method thereof. Background technique [0002] With the continuous optimization of polyurethane raw materials and related formulation processes, polyurethane synthetic leather has penetrated into all aspects of people's lives. Polyurethane treatment agent can endow polyurethane synthetic leather with more excellent properties, especially to improve the surface mechanical properties of synthetic leather, such as wear resistance and scratch resistance. Synthetic leather is composed of organic polymer compounds, which is not easy to conduct electricity, but it will inevitably generate friction with the body during use, and it is very easy to generate static electricity. If static electricity cannot be derived from the surface of synthetic leather in time, excessive static electricity accumulation can easily lead to some ac...
