Process for preparing surface material and skin material with improved mud elasticity

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...
