The invention belongs to the technical field of building construction, and particularly relates to a terrazzo-like prefabricated glass fiber reinforced plate and a preparation method thereof, aiming at solving the problems of large loss and easy deformation in the manufacturing process of a prefabricated glass fiber reinforced plate with a radian. The cement-based color paste is prepared from cement, aggregate, white sand, white powder, red powder, black powder, yellow powder, mucilage and water according to a certain proportion at normal temperature. Through the mixing of colors proportion and the addition of fine aggregate, the GRC plate with plasticity is more similar to the terrazzo in appearance and texture, so that the function that the terrazzo cannot be flexibly molded and curved is achieved. The light and high-strength characteristics of the GRC plate are ensured while the appearance effect is achieved.
Description
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to a terrazzo-like prefabricated glass fiber reinforced plate and a preparation method thereof.
Background
The general production and manufacturing methods of the glass fiber reinforced plate can be divided into:
(1) and (3) a spraying process: the spray process is the earliest and most used method of manufacturing glass fibre reinforced cement (GRC) articles, including manual spraying and automatic spraying. The first British building research institute (BRE) made glass fiber reinforced cement (GRC) articles in this way in the early 70 th century. The spraying process, whether manual or mechanical, requires specially trained operators and specialized equipment.
(2) The premixing process comprises the following steps: the premixing process is that the chopped glass fiber and the cement mortar matrix are stirred together to form a uniform glass fiber cement mixture, and then the product is prepared by a pouring or spraying method. The premixing process can be divided into a premixing pouring process and a premixing spraying process according to different molding methods. The pre-mix casting process is similar to the process of precast concrete products, and is often supplemented with a vibration process during the casting process.
However, the existing prefabricated glass fiber reinforced plate with radian has the problems of large loss, easy deformation and the like in the manufacturing process.
