High-strength efficient cement-based light transmission material and preparation method thereof

Abstract

The invention provides a high-strength efficient cement-based light transmission material and a preparation method thereof, belonging to the field of novel building materials. The high-strength efficient cement-based light transmission material is prepared from the following materials in parts by weight: 100 parts of light calcined magnesia, 65-135 parts of magnesium chloride aqueous solution, 0-60 parts of admixture, 10-80 parts of light transmission fibers, 0.1-1 part of defoamer, 1-10 parts of polyvinyl alcohol micro powder, 0.1-1 part of phosphoric acid and 0.5-3 parts of ferrous sulfate. The preparation method has the advantage of preparing the high-strength efficient cement-based light transmission material based on the characteristics such as high strength, high abrasion resistance, high glossiness, low basicity and the like of the magnesium oxychloride cement. The novel light transmission material not only has good light transmittance performance to the visible light, but also reduces the chemical corrosion action of the cement base body to the light transmission fibers while ensuring the original mechanical properties of the cement base, as well as has the characteristics such as high strength, high durability, high ornamental value and the like.

Description

technical field [0001] The invention belongs to the field of new building materials, and in particular relates to a high-strength and high-efficiency cement-based light-transmitting material and a preparation method thereof. Background technique [0002] Cement-based materials are indispensable raw materials in modern construction projects, but they do not have light-transmitting properties. Therefore, in general buildings, external and internal walls need to open windows for lighting or set up independent light sources. The cement-based light-transmitting material compounded by light-transmitting fibers and cement can make the building space obtain green and environment-friendly light sources without the above-mentioned operations. Not only that, cement-based light-transmitting materials can also be used as interior decoration materials or outdoor landscape materials, which have good ornamental properties, and have completely different decorative effects and wider applicati...

Problems solved by technology

[0004] The existing reports on cement-based light-transmitting materials show that most of them are only related to its application field and its unique light-transmitting effect, but there are few reports on cement-based light-transmitting materials and their preparation methods. There are still many problems in the process of optical material components that have not been perfected. The main problems in this field are:

[0005] First, the cost of the raw material of cement-based light-transmitting materials—light-transmitting fibers is high, and the utilization rate of light-transmitting fibers in the preparation process is low, which significantly increases the cost of cement-based light-transmitting materials; second, a large amount of cement-based light-transmitting materials The incorporation of light-transmitting fibers will have a negative impact on the strength and compactness of the cement matrix, which makes the preparation of raw materials and processes more demanding, and has certain restrictions on the application range of cement-based light-transmitting materials; The poor adhesion between the organic coating and the cement matrix causes the light-transmitting fibers to easily move relative to each other, and the light-transmitting fibers are easy to protrude or fall off from the cement matrix, which affects the appearance and durability of cement-based light-transmitting materials; Fourth, The cement matrix will produce volume effect during the process of hydration and hardening or under the influence of the external environment, resulting in cracks or breaks in the cement matrix and light-transmitting fibers, thus affecting the durability, light transmission and appearance of cement-based light-transmitting materials; Fifth, optical fiber materials are generally quartz products, which are easily corroded in high-alkalinity cement substrates, which will reduce the later light transmission performance of cement-based light-transmitting materials
