Polyvinyl alcohol (PVA) foamed collodion cotton with vegetable starch and bamboo carbon powder and preparation method thereof

Abstract

The invention relates to polyvinyl alcohol (PVA) foamed collodion cotton with vegetable starch and bamboo carbon powder, comprising at least one polyester fibre base material with a penetrating pore structure and PVA foam materials containing the vegetable starch and the bamboo carbon powder, wherein the PVA foam materials can enable the base material to be in an inclusion state, and are subjected to aldehyde acetal by using formaldehyde. The preparation method of the PVA foamed collodion cotton comprises the following steps: putting the polyester fibre base material with a penetrating pore structure into a preset-shaped container; pouring the PVA foam sample material containing the formaldehyde and hydrochloric acid in the container; generating an aldolization between the PVA foam sample material and the formaldehyde, thus the PVA foam materials enable the base material to be in an inclusion state; and after a die is filed with the PVA foam materials, warming, foaming and shaping, wherein the hydrochloric acid serving as a catalyst can generate a catalytic reaction to fasten the whole reaction speed.

Description

technical field [0001] The invention relates to foamed collodion, in particular to a PVA foamed collodion with vegetable starch and bamboo carbon powder and a manufacturing method thereof. Background technique [0002] At present, the general cleaning sponge is used to remove scale by moistening the sponge with water. Therefore, the water absorption effect is the main consideration in the material selection of the sponge, and the PVA (polyvinyl alcohol) foam material has a relatively high Good hydrophilicity, so it has become the most commonly used material for foam. Although the aforementioned PVA (polyvinyl alcohol) foam has the advantage of good water absorption, but because the material itself is relatively soft, and the surface is mostly smooth or porous, it can effectively absorb dirt or Water stains, but for the dirt stuck on the floor, it is difficult to scrape off the dirt because of its hardness is too soft, resulting in unsatisfactory cleaning performance, so it ...

AI Technical Summary

Problems solved by technology

The manufacture of this type of sponge requires secondary processing for spraying glue or pasting the pickle cloth, resulting in an increase in its cost, and because the cleaning surface is limited to the treated or pasted pickle cloth side, The cleaning efficiency of other parts is quite unsatisfactory. Therefore, when the cleaning surface is worn out after a period of use, the entire sponge must be discarded because it cannot be used, which will cause waste invisibly and is not in line with the principle of economic benefits.

[0004] Since the existing rubber sponges and cleaning sponges have different deficiencies, which greatly affect their practicability, the inventor believes that it is necessary to make an overall overall improvement to improve their cleaning performance
