Problems solved by technology

Also because it is not delicate enough, it looks beautiful from a distance, but rough when viewed up close. If the skin is not delicate enough, most people will find it difficult to accept it.
[0003] Basically, users who have used diatom mud products will feedback that the texture is rough, it is difficult to take care of after being dirty, and it is easy to break into small pieces and fall off after collision.
It needs to be handled with care in home use, otherwise it will not be able to continue to be used as a foot pad after being broken, which brings great inconvenience to users
[0004] At present, the diatom mud bathroom mats used at home and abroad generally use 70% diatomaceous earth, 30% slaked lime and plant fibers. The whole is like a piece of gypsum board, with heavy quality and poor touch.

Abstract

The invention relates to a diatom ooze sponge ground mat and a preparation method thereof. The diatom ooze sponge ground mat comprises a bottom layer, a middle layer and a surface layer which are arranged in a layered mode from bottom to top. The bottom layer is a fabric layer. The middle layer comprises diatomite, diisocyanate, polyether, silicone oil and stannous octoate; and the surface layer is a fabric layer. The middle layer is prepared from the following raw materials in parts by weight: 3 to 5 parts of diatomite, 25 to 30 parts of diisocyanate, 25 to 30 parts of polyether, 4 to 6 parts of silicone oil and 1 to 2 parts of stannous octoate. According to the diatom ooze sponge ground mat, the water absorption of the material is enhanced under the condition that the diatom ooze sponge ground mat keeps rebound and soft, and the comfort of the product is improved by compounding two layers of fabrics; through testing, the tearing strength, the shore hardness, the tensile strength, the elongation at break, the rebound rate and the water absorption rate of the diatom ooze sponge ground mat all reach better levels; and the preparation process is simple and easy to control, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of daily necessities, and in particular relates to a diatom mud sponge floor mat and a preparation method thereof. Background technique [0002] Diatom mud floor mat is a kind of water-absorbing material floor mat commonly used in the home. It has a hard texture. Long-term use will aggravate the cracking and breaking of the diatom mud material. Also because it is not delicate enough, it looks beautiful from a distance, but rough when viewed up close. If the skin is not delicate enough, most people will find it difficult to accept it. [0003] Basically, users who have used diatom mud products will report problems such as rough texture, difficult to take care of after being soiled, and easy to break into small pieces after collision. In the middle of home use, it needs to be handled with care, otherwise it will not be able to continue to be used as a foot pad after being broken, which brings great inconvenience to use...
