Anti-static sponge

Abstract

The invention discloses an anti-static sponge, which is prepared from the following raw materials in part by weight: 80 to 110 parts of polyether glycol, 60 to 70 parts of toluene diisocynate, 1 to 5 parts of polysiloxane, 0.1 to 0.5 part of triethylene diamine, 0.1 to 1.0 part of stannous octoate, 2 to 8 parts of alkaline metal and 4 to 5 parts of water. When the anti-static sponge prepared by the invention by adding anti-static alkaline metal salt into the conventional sponge foaming raw material is used for packaging electronic products and other products, the electronic products and otherproducts do not generate static in a transport process, so that the electronic products are better protected. The anti-static sponge has the advantages of high elasticity, good antistatic effect, safety, environmental friendliness, and the like.

Description

technical field [0001] The invention belongs to sponge materials, more specifically an antistatic sponge. Background technique [0002] When ordinary sponges are used as packaging materials, friction will occur with the outer packaging and the packaged objects during the transportation of the goods. Static electricity is naturally generated during this friction process. Although this kind of static electricity is small, it will still affect or even cause damage to some sensitive electronic parts. [0003] At present, there are some similar anti-static sponges in the market, such as Chinese patent, application number: 03228523.X, the patent name is: an anti-static mat, which discloses a table mat or floor with anti-static function. The mat includes an antistatic layer and a conductive layer. There is a sponge-type antistatic layer with a microporous structure between the antistatic layer and the conductive layer. The plastic antistatic layer, the sponge-type antistatic laye...

Although this kind of static electricity is small, it will still affect or even cause damage to some sensitive electronic parts.

[0003] At present, there are some similar anti-static sponges in the market, such as Chinese patent, application number: 03228523.X, the patent name is: an anti-static mat, which discloses a table mat or floor with anti-static function. The mat includes an antistatic layer and a conductive layer. There is a sponge-type antistatic layer with a microporous structure between the antistatic layer and the conductive layer. The plastic antistatic layer, the sponge-type antistatic layer, and the plastic conductive layer are laminated by heat pressing Combined into one body, the patented product has soft hand feeling and high flatness, which avoids the problem of uneven conductivity caused by crepe, not only ensures good and long-lasting anti-static performance, but also prolongs the service life of the product. The structure of the product is complicated, and the use of a large amount of plastic leads to high cost, making it difficult to promote and use it on a large scale

[0004] In addition to anti-static sponge, anti-static packaging materials also include other similar products. For example, the Chinese patent application number is: 200610008067.5, and the patent name is: an anti-static packaging material, which discloses an anti-static packaging material, which contains at least one layer of conductive Polymer layer, the conductive polymer layer is composed of carbon powder, polyurethane, additives and solvents, which has a good effect of preventing static electricity, but the production process is relatively complicated and the shockproof effect is poor
