Problems solved by technology
[0003] At present, the widely used exterior wall decorative panels are aluminum-plastic panels or stone panels. These two decorative panels are rigid decorative panels. In some special places, soft materials need to be installed, such as kindergarten exterior wall skirts. The bumps during play need to be covered with soft materials. In the prior art, artificial leather is often used to cover sponges. This material is not waterproof and will age quickly after being exposed to the sun and rain, and its service life is extremely short.
Moreover, this cladding material completely surrounds one wall, which does not look good

Embodiment 1
[0020] A production method of a flexible building decorative board, comprising the steps of:
[0021] 1) Preparation of the base layer: mix the mortar, sodium trimetaphosphate, and cornstarch according to the weight ratio of 100:0.03:1, then add water 1.1 times the weight of the above mixture, mix and stir evenly, and then divide it into A, B two parts slurry;
[0022] 2) Add 0.5% glass fiber and 0.02% defoamer to Part A slurry and stir evenly;
[0023] 3) Continue to stir the B part slurry, and pass compressed air into the B part slurry during the stirring process, so that the B part slurry is full of air bubbles;
[0024] 4) Pour part A slurry into the formwork, pour B part slurry after scraping, and then scrape the surface of B part slurry, the thickness ratio of A part slurry and B part slurry in the formwork is 4:1 ; Obtain the base board after standing and drying;
[0025] 5) Production of adhesive: by weight, 20 parts of asphalt, 35 parts of activated rubber powder, ...

The invention relates to a flexible building decorative board production method. The method includes the following steps that a base layer is prepared, wherein plaster, sodium trimetaphosphate, corn starch and water are mixed to form A slurry and B slurry; glass fiber and a defoaming agent are added into the A slurry and evenly stirred; compressed air is introduced into the B slurry; the A slurry is poured into a formwork and scraped flat, then the B slurry is poured into the formwork, and a base layer board is obtained after still standing and drying; an adhesive is prepared, wherein ethylene propylene rubber powder, polypropylene, light calcium carbonate, antioxidant and a coloring agent are added into a closed high-speed mixer according to the proportion for mixing and high-speed stirring; the processed raw materials are guided into an extruder and subjected to blending, kneading and extrusion; the adhesive is poured on the surface of the base layer board and scraped flat, an aluminum-plated film covers an upper flexible layer in a face-down mode, and a decorative board is obtained after cooling. The decorative board has the advantages of being high in strength, long in service life, resistant to high temperature and low temperature and the like.
