Description
Technical Field
The application relates to the technical field of functional sponge materials, in particular to an antistatic sponge prepared from single-walled carbon nanotubes and a preparation method thereof.
Background
Polymer products such as foam, sponge, plate and the like have the advantages of good appearance, light weight, good electrical insulation, easy dyeing, easy molding and the like, and are widely applied to industries such as packaging materials, decoration and the like. However, most of plastic products are dry and insulating, when the plastic products are used as packaging materials, friction is easily generated between the plastic products and packaged objects in the cargo carrying process, static electricity is naturally generated in the friction process, when the packaged objects are sensitive electronic parts, the generated static electricity can influence or even damage the electronic parts, and electric shock accidents or fires can be generated when the packaged objects are severe. The plate and other hard materials have high density, and are convenient to carry out antistatic treatment, so that the antistatic plate is manufactured. Because the inside air holes of such plastics as foam, sponge and the like are rich, the pores are relatively large, and the antistatic treatment is inconvenient, the preparation of the antistatic sponge is not perfect so far.
In the related art, in order to reduce the surface resistance value of the sponge product, an ex-situ method such as soaking, dipping, spraying, coating and the like (for example, a preparation method of hydrophobic and oleophilic polyurethane sponge is disclosed in Chinese patent with publication number of CN 103342827A) is often adopted, and an antistatic agent component is loaded on the surface of a skeleton of an internal pore canal agent of the sponge product; in addition, in order to reduce the surface resistance value of the sponge product, a method of adding an antistatic component into the raw material before foaming the sponge product is adopted, wherein the added antistatic agent mainly comprises carbon black, carbon fiber, alkali metal salt or conductive polymer (for example, an antistatic sponge is disclosed in Chinese patent publication No. CN 102134302A), and the method has poor compatibility of the antistatic component and the sponge raw material, is difficult to uniformly disperse in the foaming material, is easy to agglomerate, and causes the finally prepared sponge product to have unsatisfactory antistatic effect. Based on the above statement, the application provides an antistatic sponge prepared from single-walled carbon nanotubes and a preparation method thereof, aiming at improving the antistatic effect of a sponge product and achieving the effects of lasting antistatic and delaying the service life of the sponge product.

Performance testing
The antistatic sponges of examples 1 to 6 and comparative examples 1 to 2 of the present application were tested for their properties, respectively, as follows:

as can be seen from the data shown in table 1: the antistatic sponges prepared in examples 1-6 of the present application have remarkable and durable antistatic effect, excellent tensile properties, tear properties and low compression set.
From examples 2 and 4, it can be seen that: under the condition that other factors are unchanged, the polyol is a mixture of polyether polyol and rosin polyol, so that the antistatic performance and the comprehensive mechanical performance of the sponge product can be remarkably improved, and particularly as shown in fig. 1 and 2, the polyether polyol 330N and the rosin polyol are singly used for prefabricating the carbon nanotube dispersion, although a good pre-dispersing effect can be achieved, a small amount of agglomeration exists, and in the embodiment 4 of the application, the two are mixed and jointly dispersed, so that the agglomeration problem can be well solved, and the overall performance is further improved.
