Abstract

The invention discloses a composite blast furnace mineral powder and a synthetic material made from the same. The composite blast furnace mineral powder comprises the following materials in percentage by weight: 40-98.4% of blast furnace mineral powder, 7-20% of acrylic polymer emulsion or 1.5-3% of redispersible latex powder, 0.1-2% of polyvinyl alcohol fibers, 0-3% of pigment and the balance of stuffing. Waste materials are recovered and utilized, so that the composite blast furnace mineral powder and the synthetic material are beneficial to the comprehensive utilization of resources. Compared with a concrete fiber plate, the synthetic material which is made by pressing the composite blast furnace mineral powder has better toughness and can be formed in one step during manufacturing without autoclaved curing. Compared with a woodwork plate, the synthetic material made from the dry composite powder has the advantages that the fireproofing capability achieves grade A, the released volatile organic substances such as methanal are extremely few, the wood resource is saved, and the like. The composite blast furnace mineral powder can also be pressed to sectional bars or brick blanks.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a blast furnace slag composite powder and a composite material made from it. Background technique [0002] Blast furnace slag is a potentially active mineral admixture obtained by grinding water-quenched and granulated blast furnace slag to a specified fineness. When the surface area reaches 400cm 2 When it is above / g, it has the characteristics of ultra-fine particles and high activity. At present, it is mainly used as an admixture of concrete to replace part of cement, and it is one of the constituent materials for the production of high-strength concrete. But the application field of blast furnace slag is still relatively limited. Contents of the invention [0003] The object of the present invention is to provide a kind of blast furnace slag composite powder and the composite material made by it. [0004] In order to solve the above problems, the technical...
