Embodiment 1

[0019] Embodiment 1 The manufacturing method of the cushion includes the pretreatment step of sponge or foamed PU material; the sponge or foamed PU material is broken, so that the sponge or foamed PU material (the PU material after the foaming process, the same below) ) step of forming powder (particles with a smaller maximum outer diameter); pour the sponge or foamed PU material that has formed powder into a container, and feed gas into the container to make the sponge or foamed PU material The step of raising the container body, and then spraying atomized glue into the container to make the surface of the sponge or foamed PU material in the form of powder wetted by glue; The step of pouring the sponge or foamed PU material into the mold, and using a hot press molding machine at a temperature of 150°C to form a cushion; the step of demoulding the cushion from the mold.

Embodiment 2

[0020] Embodiment 2 The manufacturing method of the cushion includes the pretreatment step of sponge or foamed PU material; the step of crushing the sponge or foamed PU material to form the sponge or foamed PU material; The sponge or foamed PU material is poured into the container, and the gas is passed into the container to make the sponge or foamed PU material rise in the container, and then spray the atomized glue into the container to make it into powder. The surface of the sponge or foamed PU material is wetted by glue; the sponge or foamed PU material that is in the form of powder and whose surface has been wetted by glue is poured into the mold, and the temperature is 200 ° C by using a thermocompression molding machine. The step of thermoforming the mat body; the step of releasing the mat body from the mold.

Embodiment 3

[0021] Embodiment 3 The manufacturing method of the cushion includes the pretreatment step of sponge or foamed PU material; the step of crushing the sponge or foamed PU material to form the sponge or foamed PU material; The sponge or foamed PU material is poured into the container, and the gas is passed into the container to make the sponge or foamed PU material rise in the container, and then spray the atomized glue into the container to make it into powder. The surface of the sponge or foamed PU material is wetted by glue; pour the sponge or foamed PU material that is in the form of powder and the surface has been wetted by glue into the mold, and use a thermocompression molding machine at a temperature of 180 ° C. The step of thermoforming the mat body; the step of releasing the mat body from the mold.

[0022] In the above-mentioned embodiment, the structure of the container is such that the air flow inside can communicate with the outside world, but the sponge or foamed P...

Abstract

The invention belongs to the technical field of manufacturing sponge or a foamed PU (Poly Urethane) material into a cushion. The method for manufacturing cushions comprises the following steps of: carrying out pretreatment on the sponge or the foamed PU material; crushing the sponge or the foamed PU material, so as to form the sponge or the foamed PU material into micro-particles; pouring the sponge or the foamed PU material formed as micro-particles into a container, introducing gas into the container to enable the sponge or the foamed PU material to rise up, and spraying glue in atomization into the container so as to wet the surface of the sponge or the foamed PU material at the micro-particle state by using the glue; pouring the sponge or the foamed PU material which is at the micro-particle state and is wetted by the glue into a mold, and forming the foamed PU material into a cushion body by using a hot press molding machine at 150-200 DEG C in a hot press molding manner; and demolding the cushion body. Waste sponge or foamed PU materials can be utilized to manufacture cushions with low manufacturing cost and odourlessness and environmental-friendliness.

Description

technical field [0001] The invention belongs to the technical field of making sponge or foamed PU material into a cushion. Background technique [0002] At present, there are a wide variety of mats on the market, such as common mouse pads, floor mats, seat cushions, and table mats in daily life, sound insulation mats and heat insulation mats used in the construction industry, and foot pads used in the automotive industry. [0003] Currently, most mats are mainly made of rubber materials. However, the rubber material is smelly, not environmentally friendly, and the rubber material is prone to aging and hardening, resulting in a shorter service life of the mat. Furthermore, due to the high price of rubber materials, the price of mats made of rubber is correspondingly high. Contents of the invention [0004] The object of the present invention is to provide a method for manufacturing a mat, which has low manufacturing cost and the manufactured mat is odorless and environmen...
