Description

Composite carbon black material for artificial stone and preparation method and application thereof Technical Field The invention relates to the field of building materials, in particular to a composite carbon black material for artificial stone and a preparation method and application thereof. Background The artificial stone has the advantages of adjustable color, no color difference in large-area paving, capability of utilizing leftover materials extracted from natural stone, energy conservation, environmental protection and the like, and becomes an important direction of the development of the existing decorative stone industry. The artificial stone is made up by using high-molecular polymer, inorganic gelatinizer or their mixture as adhesive material, using natural stone material crushed (powder) material and aluminium hydroxide powder as main raw material, adding pigment and other adjuvant, stirring, mixing and solidifying. The zero silica quartz stone plate has unique advantages in the decoration field because of containing no siliceous additive, but the dark (especially black) zero silica quartz stone plate has poor waterproof and anti-penetration performances in the production and use processes because of insufficient compatibility of carbon black and a base material, and the plate has higher water absorption rate, is easy to cause uneven internal stress due to moisture penetration, causes glass explosion, and limits the application range. Disclosure of Invention In order to make up the defects in the prior art, the invention provides the composite carbon black material for the artificial stone, which can enhance the compatibility with a quartz stone base material and reduce the water absorption rate of the plate, thereby improving the antiknock performance and the waterproof and impermeable performance. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The composite carbon black material for artificial stone includes the material comprising carbon black 10 weight portions, silicone compounding agent 3 weight portions, and composite carbon black material with water content less than 1% and grain size less than or equal to 10 microns. The invention also provides a preparation method of the composite carbon black material for the artificial stone, which comprises the following steps: S1, adding 10 parts of carbon black into mixing equipment, adding 3 parts of siloxane complexing agent under stirring, and stirring for 30-40 minutes to obtain a mixture; s2, placing the mixture into drying equipment, and drying for 8-10 hours at 80-100 ℃ to ensure that the water content of the mixture is less than 1%; and S3, placing the dried mixture in grinding equipment, and grinding until the particle size of the mixture is less than or equal to 10 microns to obtain the composite carbon black. The invention also provides application of the composite carbon black material for the artificial stone, wherein the composite carbon black is added into quartz raw materials, and is uniformly mixed and pressed into quartz slabs, and the composite carbon black accounts for 2-6% of the mass of the quartz slabs. Optionally, the quartz stone raw material is black quartz stone raw material, and the composite carbon black accounts for 2-5% of the mass of the quartz plate. Further, the black quartz stone raw material comprises 80 parts of quartz sand, 10 parts of resin and 2 parts of auxiliary agent by weight. Optionally, the quartz stone raw material is white quartz stone raw material, and the composite carbon black accounts for 3-6% of the mass of the quartz plate. Compared with the prior art, the invention has the following beneficial technical effects: 1. The explosion-proof performance of the plate is improved.
