Problems solved by technology

[0003] Due to the excellent performance and low cost of hollow microspheres, they are widely used in building materials, such as heat insulation building materials, sound insulation building materials and wear-resistant building materials, etc. The bonding effect is poor, so in the process of using the finished building materials, it is prone to powder removal of the building materials, which affects the quality of the building materials. The strength of the hollow microsphere is low, and it is easy to be broken in a large amount during the process of high-pressure pressing and mixing, which will affect the normal use of the hollow microsphere material, and the hollow microsphere is a kind of hollow microsphere, which is porous in the inside, vitrified and closed on the surface, and is in the shape of a spherical body with a small diameter. particles, but the effect of surface vitrification sealing is not complete, so the hollow microspheres also have a certain degree of water absorption. During the production process, these open pore structures will absorb a large amount of water or other materials, resulting in the heat insulation of the hollow microspheres. The thermal insulation effect is reduced. In order to solve the above problems, a kind of building board with high structural strength and good structural strength that is not easy to depowder is provided. The present invention provides the following technical solutions

Abstract

The invention discloses a plate based on a silicon-aluminum-based hollow microsphere material and a production process of the plate. The plate is prepared from the following raw materials in parts byweight: 8-14 parts of modified silicon-aluminum-based hollow microspheres, 36-44 parts of modified inorganic filler, 7-9.5 parts of modified fiber material and 12-15 parts of adhesive emulsion. According to the preparation method, the surfaces of the silicon-aluminum-based hollow microspheres are treated through a silane coupling agent, then the surfaces of the silicon-aluminum-based hollow microspheres are coated with partially reduced graphene oxide; and the graphene coated on the surfaces of the silicon-aluminum-based hollow microspheres is reduced through roasting treatment and heating treatment in a hydroiodic acid steam environment, so as to obtain modifiedsilicon-aluminum-based hollow microspheres; the pores in the silicon-aluminum-based hollow microbeads can be sealed through graphene coating, so that a large amount of liquid materials are prevented from entering pore channel structures of the silicon-aluminum-based hollow microbeads in the machining process, the heat preservation effect of the silicon-aluminum-based hollow microbeads is improved, and the density of a finished plate is reduced.
