Description

Technical Field

[0001] The present invention relates to the field of building decoration and decorative materials, and in particular to a glass fiber composite aluminum hydroxide powder and a preparation method thereof, and artificial stone prepared therefrom and a preparation method and application thereof. Background Art

[0002] In the field of building decoration materials, artificial stone is welcomed by the market due to its unique advantages, such as reproducibility, easy processing, no color difference, etc. It occupies an important position in the decoration industry, especially in the field of kitchen and bathroom countertops. The artificial stone industry is an energy-saving and environmentally friendly industry that turns waste into treasure and recycles resources. The industry makes full use of various low-value waste stone resources. The production process does not require a large amount of fuel consumption and has no waste gas emissions. It has become an important direction for the development of the decorative stone industry. Artificial stone is mainly made of unsaturated polyester resin as a bonding material, natural stone fragments or calcium carbonate powder, aluminum hydroxide powder, silica powder and other inorganic fillers, and then added with pigments and a small amount of initiator. It is processed through stirring, mixing, condensation and curing. The main products are solid surface material artificial stone, artificial quartz stone, artificial granite, etc. Due to the large shrinkage of unsaturated polyester resin, artificial stone has a larger thermal expansion coefficient compared to natural stone or ceramic products, which leads to serious challenges to the dimensional stability, deformation resistance and long-term resistance to sudden cooling and heating of artificial stone, which seriously limits the application of artificial stone products in large-sized or special-shaped products. How to reduce the thermal expansion coefficient of artificial stone to ensure the long-term deformation resistance and cracking resistance of artificial stone products, expand the application range of artificial stone products, and promote the development of the artificial stone industry is of great significance. To this end, some patents have been published:

[0003] 1. As in CN201410629239.5, unsaturated polyester is modified by using alkaline earth metal oxide / hydroxide, and then the modified unsaturated polyester is used as a binder to prepare artificial stone, thereby achieving the effect of reducing the thermal expansion coefficient α of the artificial stone and increasing the thermal transition point Tt at the same time.

[0004] 2. As in patent CN202110889101.9, bamboo strips are used as raw materials, and steam explosion fibers are obtained by defibrination through steam explosion to obtain steam-exploded fibers rich in hydroxyl groups on the surface. The steam-exploded fibers are then subjected to surface corona treatment to obtain modified fibers. The modified fibers are then used as templates, and calcium sulfate whiskers are deposited on their surface to obtain fibrous calcium sulfate whiskers. Then, sodium silicate and hydrochloric acid are reacted to produce orthosilicic acid precipitates that adhere to the surface of the fibrous calcium sulfate whiskers. The precipitates are then hydrolyzed under high temperature and high pressure to produce nano-silicon dioxide that is coated on the surface of the fibrous calcium sulfate whiskers to obtain silicon-coated modified fibrous calcium sulfate whiskers, which are used as artificial marble fillers and compounded with unsaturated polyester matrix, and cured under the action of a curing agent to finally produce anti-fouling and anti-cracking artificial marble.

[0005] However, the above patents have the following problems:

[0006] 1. Modifying unsaturated polyester with alkaline earth metal oxides / hydroxides and using it as a binder for artificial stone can indeed reduce the expansion coefficient α of artificial stone. However, the introduction of alkaline earth oxides / hydroxides into the artificial stone system will inevitably affect the corrosion resistance of the artificial stone products and have an adverse effect on the long-term stability of artificial stone products.

[0007] 2. By using modified fibers as a matrix and obtaining silicon-coated modified fibrous calcium sulfate whiskers through multiple deposition reactions as artificial stone fillers and compounding them with unsaturated polyester matrix, anti-fouling and anti-cracking artificial marble products are obtained. The preparation process of the filler is very complicated and cumbersome, and requires multiple high-temperature and high-pressure treatments. The production cost is too high, making it difficult to promote it on a large scale as a daily necessity.

[0008] Therefore, there is an urgent need in the art for a method for preparing artificial stone, which can reduce the thermal expansion coefficient of the artificial stone to ensure the long-term anti-deformation and anti-cracking performance of the artificial stone product.
