Problems solved by technology

[0002] Cleaning products currently on the market made of polyvinyl alcohol foam, melamine foam, natural sponge and other foam materials are usually made by cutting and slicing. The water will immediately wash away the detergent contained in it, and the cleaning effect is average
In addition, because it is a monolithic or monolithic entity, the foaming ability is limited, and the ability to absorb and pay water is also limited.

Embodiment Construction

[0019] The preparation method of hollow foam of the present invention, technology first is to cut polyvinyl alcohol foam or melamine foam or the foaming material of natural sponge into two pieces of foam, standby; Add the starch into hot water at 75°C, stir and mix quickly to make it gelatinized and become starch mixed water for later use; soak the foam in the starch mixed water to make the foam solidified, which is convenient for the next stamping, and then Take out and squeeze out the water, put it on the grid to dry, until the foam is dry and harden, and set aside; use a mechanical punch press to pressurize the hardened foam to make it thinner and become a thin version of foam, set aside ;Punch the thin plate according to the finished product style and set it aside; stack the two thin foam plates neatly, and then sew or thermally bond the inner edges of the two thin foam plates. The distance between the stitching or bonding marks and the edge of the thin foam plate is 0.3cm...

Abstract

The invention provides a method for making hollow foamed plastic, belonging to the chemical field. The technological steps include that: firstly two or more foamed plastics are made, the foamed plastics are soaked into starch mixed water and taken out to be dried, the foamed plastics are pressurized to be foamed plastic thin plate and then formed for spare use, then the two or more foamed plasticsare coincided and the inner margins are seamed or bonded under heat, and finally glue in the foamed plastic is cleaned out, so that the foamed plastic reinstates. The position of seaming line or bonding line is naturally clad or halfly wrapped owing to material extrusion, and natural hollow state is realized, namely hollow foamed plastic with strong foaming power is formed.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a manufacturing process of hollow foam. Background technique [0002] Cleaning products currently on the market made of polyvinyl alcohol foam, melamine foam, natural sponge and other foam materials are usually made by cutting and slicing. The moment of water will immediately wash away the contained detergent, and the cleaning effect is average. In addition, because it is a monolithic or monolithic entity, its foaming ability is limited, and its ability to absorb and pay water is also limited. Contents of the invention [0003] The object of the present invention is to propose a method for making a hollow foam in view of the technical defects in the prior art. [0004] In order to achieve the above object, the technical scheme of the present invention is as follows: the manufacture method of hollow foam, its processing step comprises: [0005] a. Cut polyvinyl alcohol foam o...
