Abstract

The invention relates to the technical field of sticky mats, and in particular relates to a sticky mat and a production process thereof. The sticky mat comprises multiple layers of sticky films and adhesive layers arranged between every two adjacent layers of sticky films, wherein each sticky film consists of an outer layer, an intermediate layer and an inner layer, which are co-extruded and adhered. According to the sticky mat and the production process thereof, the outer layer of the sticky film is made from a material capable of maintaining high wettability of the outer layer of the sticky film, and is matched with an adhesive with a specific formula, so that the adhesion force between the outer layer of the sticky film and the corresponding adhesive layer is greatly strengthened, and the adhesive is prevented from dropping off in a using process; the intermediate layer of the sticky film has a function of maintaining the strength of the sticky mat; the inner layer of the sticky film is made from a material capable of maintaining high surface smoothness of the inner layer of the sticky film, so that weak adhesion force between the inner layer of the sticky film and the corresponding adhesive layer is favorably maintained, and the used sticky film can be conveniently torn off. The production process is low in cost and simple, and by corona treatment, the wettability of the outer layer of the sticky film is improved, and the adhesion force between the outer layer of the sticky film and the corresponding adhesive layer is greatly strengthened.

Description

A kind of sticky mats and manufacture craft thereof

Technical field

The present invention relates to sticky mats technical field, relate in particular to a kind of sticky mats and manufacture craft thereof.

Background technology

Sticky mats is the gateway that need to keep clean environment place for being placed on, and prevents from that the sticky dust of sole from bringing into need to keep in clean environment place, thereby reaches the object keeping clean.

Sticky mats comprises several layers of dust-binding membrane and is arranged at the adhesive between dust-binding membrane, dust-binding membrane consists of the film of skin, intermediate layer and the three-layer co-extruded bonding of internal layer, adhesive on dust-binding membrane skin has been covered with dust all in the time of need to changing, need to tear this dust-binding membrane, this just requires the cohesive force of the adhesive of dust-binding membrane internal layer and its below can not be too large; And in order to prevent that adhesive from coming off from dust-binding membrane skin, just need adhesive and dust-binding membrane skin to have larger cohesive force.How the cohesive force problem between balance adhesive and dust-binding membrane internal layer, dust-binding membrane skin, becomes a large technical barrier, and this technical barrier of Gonna breakthrough just must be started with from the manufacture craft of the raw material of dust-binding membrane, the raw material of adhesive and whole sticky mats.

If this technical barrier can not get breaking through, sticky mats in use, with regard to there will be adhesive from dust-binding membrane come off, used dust-binding membrane is not easy to tear etc. problem, not yet occurs breaking through at present the technology of an above-mentioned difficult problem.
