Abstract
The invention discloses a regenerated fan blade fiber reinforced concrete decorative product and a preparation method thereof, and belongs to the technical field of concrete composite materials; the preparation method comprises the following steps: designing, preparing materials and a mold, preparing mortar, pouring, demolding, curing and finishing; the manufacturing materials of the decorative layer and the structural layer comprise cement, mineral admixture, sand and regenerated fan blade fibers, the regenerated fan blade fibers in the decorative layer are combined with the crack self-repairing agent, so that the cracking resistance and durability of the decorative product can be improved, and the recycled use of the fan blade can be promoted; the elastic properties of the dispersible latex in the structural layer can increase the toughness and ductility of the decorative article, making it more mechanically and durable. The decorative product doped with the regenerated fan blade fiber has excellent durability and environmental protection performance, and is suitable for popularization and application.
Description
Technical Field
The invention belongs to the technical field of concrete composite materials, and particularly relates to a regenerated fan blade fiber reinforced concrete decorative product and a preparation method thereof.
Background
GRC is a fiber concrete composite material, which adopts alkali-resistant glass fiber as a reinforcing material and cement mortar as a matrix material. Because GRCs can be made into components of various shapes and sizes, and detail and complex surface textures can be easily achieved during production, they are ideal choices for designers and architects. However, the cost of manufacturing GRC decorative articles has been high, mainly due to the high use of expensive alkali resistant glass fibers. Therefore, there is a need to find a low cost fibrous material to replace alkali resistant glass fibers.
With the rapid development of wind power generation, the number of waste wind turbine blades is increased year by year, and great attention is paid to environmental and social effects in many countries. Since wind turbine blades have a design life of 20-25 years, this means that approximately 500,000 tons of blade waste will be produced worldwide by 2034. The waste wind turbine blade is large in size and non-biodegradable, and the wind turbine blade is made of composite materials such as epoxy resin and glass fiber or carbon fiber. Since composite materials are currently difficult to recycle, researchers have conducted extensive research into their recycling technology because the polymers used are produced in an irreversible process to obtain the required durability and strength of the material while maintaining a low weight. Among them, the most common technique for recycling blades is mechanical grinding, which is a direct, economically viable physical recycling scheme for fan blades, unlike pyrolysis recycling and chemical recycling techniques. Physical recycling techniques provide a fast and efficient method of reducing the size of the waste and recycling low aspect ratio fibers. However, the fiber recovered by mechanical polishing is severely damaged, and long fibers cannot be obtained, resulting in low recovery value and poor reuse.
Disclosure of Invention
The invention aims to provide a regenerated fan blade fiber reinforced concrete decorative product and a preparation method thereof, and aims to solve the technical problems of high cost of fiber concrete composite materials and low recycling rate of fan blade fibers in the prior art.
In order to solve the technical problems, the invention adopts the following technical scheme:
the regenerated fan blade fiber reinforced concrete decorative product comprises a decorative layer, a structural layer and anchoring pieces, wherein the decorative layer and the structural layer are sequentially poured into a mold, and the anchoring pieces are embedded in the structural layer;
the decorative layer comprises the following components in parts by weight:
35-50 parts of cement;
15-20 parts of mineral admixture;
45-65 parts of sand;
25-35 parts of stone scraps;
3.5 to 5.0 portions of calcium acetate monohydrate powder;
2.5 to 4.5 parts of regenerated fan blade fiber;
0.25 to 0.5 portion of microorganism-induced calcium-based crack self-repairing agent;
0.1-0.3 part of water reducer;
14-20 parts of water;
the manufacturing materials of the structural layer comprise the following components in parts by weight:
45-50 parts of cement;
