Abstract
Relating to the field of biomass composite materials, the invention provides a biomass polymer hybrid laminated composite material and a preparation method. The biomass polymer hybrid laminated composite material and the method solve the problems that great energy consumption and high production cost exist in current artificial board production processes, the product causes serious environmental pollution, and the comprehensive performance of the material is poor. According to the different material characterization characteristics of an organic polymeric material, an inorganic polymeric material or high polymer material, arbitrary interlaminar combination is carried out, thus obtaining laminated composite materials with different characterization characteristics. The method makes full use of the molding mechanism of an inorganic polymeric material and a water-based organic polymeric material under room temperature and atmospheric pressure conditions on a biomass composite multifunctional lamination compound machine, and gives full play to the interface mixing and dissolving combination advantages of polymer materials. The material provided in the invention is free of formaldehyde and phenol, can burn for 8h under 5000KJ with no naked flame, and only a slight carbonization phenomenon exists. After immersion in clear water for 30 days, the expansion rate does not exceed 8%.
Description
technical field [0001] The invention relates to the field of biomass composite materials. In particular, it relates to a biomass polymer hybrid laminated composite material and a preparation method. Background technique [0002] At present, all kinds of composite materials produced are basically a single cohesive composite reaction system. The material of this single cohesive system is difficult to meet the leap from inorganic non-metallic materials to polymer materials, and the material of this single cohesive system Most of them adopt high temperature and high pressure molding process, so the production cost is high, and it is difficult to meet the needs of market competition. Various biogas digesters, sewage treatment ponds, gypsum boards, and calcium silicate boards produced with inorganic polymer materials use the single polymerization principle of inorganic gelling materials; and after inorganic materials are polymerized, there are high surface hardness, weak structur...
