Embodiment Construction

[0018] see figure 1 The soft terrain model sand table that can be curled is composed of a sand table surface layer 1 and a sand table surface layer support body 2 bonded below the sand table surface layer. The room temperature vulcanized silicone rubber of the sand table surface layer refers to No. 903 translucent mold silicone rubber, The polyurethane crust soft foam rubber used as the support body material for the surface layer of the sand table refers to polyurethane soft self-skin foam.

[0019] The preparation method is:

[0020] see figure 2 First prepare the topographic sand table mold 3, the topographic sand table mold is a mold cavity 31 with an open mouth, the four vertical walls forming the mold cavity are coamings 32 arranged around the terrain sand table mold, and the bottom of the mold cavity is the same as the topography. uneven;

[0021] Apply evenly colored No. 903 translucent mold silica gel on the bottom surface of the cavity, and form a silicone layer o...

Abstract

The invention provides a rollable soft terrain model sand table and a preparation method thereof. The rollable soft terrain model sand table is characterized by being composed of a sand table surfacelayer and a sand table surface layer support bonded to the lower side of the sand plate surface layer, wherein the sand table surface layer is made of room temperature vulcanized silicone rubber, andthe sand table surface layer support is made of polyurethane skinning flexible foam rubber. The preparation method includes the steps of coating a mould with the room temperature vulcanized silicone rubber and the polyurethane skinning flexible foam rubber in sequence, and performing demoulding after curing. The rollable soft terrain model sand table and the preparation method thereof have the advantages that as the sand table surface layer and the support thereof are both made of elastic materials, the sand table formed by the sand table surface layer and the support thereof can be rolled anddoes not deform after being rolled, and the sand table is convenient to carry and can be repeatedly used; the sand table has a waterproof effect.

Description

technical field [0001] The invention relates to a terrain model sand table, in particular to a curlable soft terrain model sand table and a preparation method thereof. Background technique [0002] Terrain sand table, a kind of terrain model, has the characteristics of strong three-dimensional sense and intuitive image. It includes simple sandbox and permanent sandbox. The simple sand table is made of temporary piles of sand and war chess, which has the advantages of convenient material collection, simple, rapid and economical production; the permanent sand table has the characteristics of long service life and high cost. Regardless of the simple sand table or the permanent sand table, the common feature is that they are all made of hard materials and belong to the hard sand table. The hard sand table is installed in a fixed place for use. It cannot be carried with you, which limits the use of the sand table. Contents of the invention [0003] In order to solve the abov...
