Problems solved by technology

Free TDI and MDI can be volatilized within a few years, but the damage of toxic and harmful substances in the material to the human body and the adverse impact on the environment will exist for a long time
At present, the production of synthetic leather mainly uses solvent-based PU as the basic raw material for the production of leather base and surface layers. This type of PU contains a large amount of organic solvents, which has a serious impact on the health of production workers.

Embodiment 1

[0031] 40% of soil, 51% of acrylate polymer copolymer emulsion, 5% of water, 2% of flexible agent C (organic silicon surfactant), 2% of cross-linking agent EH (low molecular condensate of polyamine polyol) and mix and stir Evenly form a colloidal slurry, and apply the slurry repeatedly on the constant temperature formwork at 120°C until the required thickness is reached, then the mold can be ejected to form an elastic runway surface. The surface pattern of the resulting elastic runway surface is determined by the texture of the formwork.

Embodiment 2

[0033] 45% of soil, 45% of acrylate polymer copolymer emulsion, 5% of water, 3% of flexible agent C (organic silicon surfactant), 2% of cross-linking agent EH (polyamine polyol low molecular weight condensate) and mix well Colloidal mud, the mud is repeatedly coated on the 90 ℃ constant temperature formwork until the required thickness is reached, and then the mold can be released to form an elastic sports surface layer. The surface pattern of the formed elastic sports scene layer is determined by the texture of the template.

Embodiment 3

[0035] 52.5% of clay, 30% of acrylate polymer copolymer emulsion, 15% of water, 1% of flexible agent C (organic silicon surfactant), 1.5% of cross-linking agent EH (polyamine polyol low molecular weight condensate) and mix well Colloidal mud, the mud is repeatedly coated on the 80 ℃ constant temperature formwork until the required thickness is reached, and then the mold can be released to form an elastic wall veneer material.

Abstract

In the preparation process of modified elastic clay surface material and skin material, clay, modifier, water and plasticizer are mixed through stirring to form slurry; the slurry is coated repeatedly onto constant temperature formwork at 52-182 deg.c until reaching the required thickness; the coating is demolded after the water volatizes to form the elastic surface material; and one layer of non-woven fabric or netted chemical fiber fabric may be combined to the elastic surface material to form the skin material. The present invention has less dependency on petroleum product, environment friendship, low cost, and high performance.

Description

technical field [0001] The invention relates to the field of materials, in particular to a method for preparing a modified mud elastic surface material and a leather material used as elastic sports ground, household, commercial ground, pavement and wall paving surface materials and industrial leather materials. Background technique [0002] The current elastic building surface materials are mainly thermoplastic elastomer products such as polyvinyl chloride (PVC), polyurethane (PU), polystyrene (PS), rubber or their mixtures, and the current synthetic leather materials are mainly PU or PVC products. These products are actually derivatives of petroleum or rubber. For products that completely rely on PVC, PU or PS as raw materials, there are currently two major problems: [0003] PU elastic surface material is widely used in paving runways and sports fields, but the component TDI / MDI contained in it is volatile and toxic. TDI is an internationally recognized highly toxic and v...
