CONSTITUTION: The mouse pad includes a non-slip sheet as foam with 0.5 to 3mm thickness made of a PCV resin. A foaming fabric nucleus is not exposed in an adherent surface of the non-slip sheet. A lint fabric(continuous indefinite type) is formed of the adherent surface of the non-slip sheet. A positive friction coefficient of the non-slip sheet is 1.1 to 1.4(KSM3009). A fiber textile is inserted into the non-slip sheet.

Description

Non-slip mouse pad and method for manufacturing same

The present invention proposes a non-slip mouse pad and a manufacturing method thereof.

The mouse pad is composed of a skin layer that contacts the mouse ball to promote the cloud of the ball and a non-slip sheet that supports the skin layer on the table. The non-slip sheet is a 3 to 7 mm thick foamed elastomer and the skin layer is a 0.2 to 08 mm thick roughening layer adhered onto the non-slip sheet. The delicately formulated rough skin layer creates a smooth and firm adhesion to the mouse ball, which makes it possible to subdivide mouse information generation, and the non-slip sheet supporting the skin layer should stably support the skin layer in the working environment. The thickness of the mouse pad is mainly determined by the thickness of the non-slip sheet.

If the mouse pad is thick, the pad protrudes over the table, which makes it unstable when the mouse leaves the pad, increases the wrist fatigue of the user, and the thinner the pad, the smaller the cushion depth of the elastomer, thus reducing the pad's non-slipness.

Conventional non-slip sheet is made of rubber-based elastomer (elastomer), EVA foam (EVA foam), urethane foam (urethane foam) and the like. Rubber-based elastomers are heavy and expensive, EVA foams are light but have low non-slip characteristics (static friction coefficient of 0.7 to 0.8, KSM3009), and urethane foams are also light and non-slip characteristics are poor (static friction coefficient of 0.7 to 0.8, KSM3009). In addition, the EVA foam and the urethane foam are inevitably slip resistant when the elastomeric foam does not have an appropriate thickness in terms of the characteristics of the material, so the thickness of the mouse pad is inevitably increased (Table 1).

Table 1

Item Rubber Elastomer EVA foam Urethane foam Proper thickness 3-7 mm 3-7 mm fault Heavy and expensive Light weight but weak slip prevention Static friction coefficient - -0.7-0.8, KSM3009 -0.7-0.8, KSM3009 Adhesion characteristics The thicker the material, the better the adhesion. The thicker the foam, the better the adhesion. non-slip condition Foam on the adherend surface exhibits non-slip characteristics under compression

Specifically, the EVA-based mouse pad cuts the foam molded to a thicker thickness (30 mm or more) to an appropriate thickness (for example, 5 to 10 mm thickness), so that the foamed tissue is exposed to the outside. When the nucleus touched the deposit, it was non-slip and therefore forced to use the mouse, poor slip prevention, and pad thickness should be at least as thick as the nucleus.

Another polyurethane (PU) foam shall be molded into a large block foam (more than 1000 mm thick) or slab foam and cut to the required thickness. Polyurethane foams also have a depth of nucleus, which causes the non-slip force when the nucleus contacts the deposit by pressing the mouse pad by that depth, so that the foam tends to be thick and similarly, the force is applied to the mouse. .

The present invention is based on PVC, non-slip pad foam tissue is to propose a mouse pad without the nucleus exposure to form a rough tissue.

Another object of this invention is that the thickness of the non-slip pad is 0.5-3 mm thin and light; The purpose of this study is to propose a mouse pad that maintains a static friction coefficient of 1.1 to 1.4 (KSM3009) to produce a very stable adhesion required for mouse use.

Another object of the present invention is to propose a thin and tough non-slip pad by inserting a fiber fabric into the non-slip pad.

Another object of the present invention is to propose a mouse pad that can be easily mass-produced and provided at a low price.

The composition of this invention non-slip sheet composition is as follows.

The non-slip sheet obtained in the process is a fiber fabric core is inserted, the tensile strength is large, the thickness is thin and light; Cotton exposed to the foam tissue nucleus and free of release paper forms a tissue roughening of the net fabric; It maintains a static friction coefficient of 1.1 ~ 1.4 (KSM3009) and has a stable adhesion so that the mouse can be used without pressing the mouse.

In the block unit heat curing process, a paste-like sheet composition is injected into a jig (open mold) of a predetermined size in a thickness of 0.5 to 1 mm and heated in an oven at 140 to 170 ° C. for 20 to 40 minutes. At this time, foaming and baking occurred in the sheet composition at the same time, 0.5 to 3 mm thick, and the coefficient of static friction was 1.1 to 1.4 (KSM3009), and the foam structure had no nucleus exposure and the continuous irregular foam structure on the surface where the jig did not touch. A non-slip sheet of a mouse pad having a rough surface of is obtained. An epidermal layer is attached to the non-slip sheet to obtain a finished mouse pad exhibiting stable adhesion.
