Problems solved by technology

There are at least two deficiencies in this method of using the adhesive: one is that the adhesive will form a thick or thin film between adjacent layers, which will more or less reduce the distance between the layers. Conductivity, especially for the above-mentioned three-layer rubber floor, this reduction effect is more obvious; the second is that the use of adhesives will cause environmental pollution and be harmful to the health of users and workers

Embodiment Construction

[0013] Unless otherwise specified, when the present invention mentions the ratio, it is all in parts by weight.

[0014] The rubber floor of the present invention is composed of three layers, namely a surface layer, a middle layer and a bottom layer, each layer contains conductive carbon black, wherein the middle layer is a foam layer. These three layers are pressed together through a vulcanization process and do not need to be bonded by adhesives. The production method in the prior art is that the middle layer is foamed in the abrasive tool, and the surface layer is bonded together with an adhesive after foam molding. The prior art cannot use a molding process because the foaming agent in the middle layer, that is, the foam layer, cannot foam evenly during short-time compression molding, because the foaming agent is not easy to uniformly disperse in the rubber composition.

[0015] In the present invention, nitrile rubber is used as the basic rubber material in the material ...

Abstract

The invention relates to an anti-static rubber floor board with a foam layer and a production method thereof. The rubber floor board consists of a face layer, a middle layer and a bottom layer. By optimizing a formula and combining the production process improvement, the multilayer combination one-step shaping and the green production are realized; the bonding by bonding agents is not needed; and the production process is simplified. The production method has the characteristic that parisons of the middle layer, i.e. the foam layer are subjected to long-time standing.

Description

technical field [0001] The invention relates to the field of flooring, and more specifically relates to rubber flooring and a production method thereof. Background technique [0002] Rubber flooring is widely used, such as electronic device production workshops, large-scale offices, some public places such as schools, airports, and transportation vehicles such as airplanes and trains. Using rubber flooring can prevent slipping and reduce noise, and because of its rich colors, it is also decorative. The role of beautification. In addition, in these places, such as workshops for producing and assembling electronic products, and offices where multiple computers and other electronic office equipment such as printers and copiers are used, a large amount of static electricity is often generated. If the static electricity is not eliminated, it will adversely affect people's health or product quality. In order to eliminate static electricity, antistatic agents and / or conductive ma...
