Polyethylene pad and method for manufacturing same

Abstract

The invention relates to a method for manufacturing a polyethylene pad, the method comprising the steps of performing foaming forming of polyethylene resin for manufacturing porous polyethylene foam with a fixed shape; covering the surfaces of the polyethylene foam with thin films, performing laminating of coating treatment and manufacturing an upper portion plate and a lower portion plate; the polyethylene foam serving as a soft pad member, overlaying and pressing the lower portion plate under the soft pad member and overlaying and pressing the lower portion plate atop the soft pad member for temporary manufacture of a polyethylene pad; forming grooves in the soft pad member through first hot working, the upper portion plate and the lower portion plate forming opposite remaining bonding portions; heating the edge portions of the temporarily manufactured polyethylene pad for a fixed time through second hot working, using a press for stamping and compressing to allow the remaining bonding portions to bond to form a bonding edge portion with a fixed width, and cutting the tail end portion of the outer side of the edge of the bonding edge portion with a cutting blade.

Description

technical field [0001] The present invention relates to a polyethylene mat and a manufacturing method thereof, and more specifically relates to a method of pressing the edge of a polyethylene mat manufactured in a laminated structure to finish the finishing process by stamping it with a press. Grooves are processed on the member to form the remaining bonding surface, and thermal processing is performed on it to form a bonding edge with a predetermined width, so that it can be bonded together more stably, and the durability is improved so that even the edge A polyethylene mat and a manufacturing method thereof that do not easily damage an adhesive surface where a finishing process is applied even if a load is partially applied. Background technique [0002] In general, mats are widely used in bedrooms, children's rooms, kindergarten facilities, restaurants, etc., and have the advantages of thermal insulation and cushioning effects such as laying on the floor to block the cold...

Problems solved by technology

[0007] The above-mentioned PVC has the advantages of weight, non-slip, and excellent cushioning effect, but has the disadvantage of increasing the cost due to high price compared with P.E. In addition, PVC mats use plasticizers called phthalates, called Phthalates are environmental hormones that are harmful to the human body

[0008] But the existing mat (200) has the following problems in the manufacturing process: the edge part is sewn with cloth, and the oblique line processing is carried out by sewing, which needs to invest a lot of time and cost.

[0011] But, still there is following problem in the mat that makes as above-mentioned method: because of elastic force, the glued part of the cushion member (230) that is laminated in the middle part of the mat, from its inner side toward the edge, thinner and more integrated, However, in the finishing process, if the cut-off position is slightly inward, the edge of the finishing process may burst due to the elasticity of the cushion member, or the same may occur when a large load is applied to the cushion during use. The problem
