The invention discloses a glass fiber reinforced plastic optical cable protective sleeve, which includes a first glass fiber reinforced plastic tube, and the first glass fiber reinforced plastic tube is made of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. The first polytetrafluoroethylene waterproof material layer is coated on the outer wall of the first glass fiber reinforced plastic pipe, and the outer wall of the first polytetrafluoroethylene waterproof material layer is glued with a first silicide heat insulation cotton layer. The glass fiber reinforced plastic optical cable protective sleeve passes through the cooperation between the first polytetrafluoroethylene waterproof material layer and the first silicide heat insulation cotton layer, so that the first polytetrafluoroethylene waterproof material layer and the first silicide insulation cotton layer The temperature resistance of the heat insulation cotton layer makes the first glass fiber reinforced plastic pipe have stable temperature resistance, and through the temperature resistance of the second polytetrafluoroethylene waterproof material layer and the second silicide heat insulation cotton layer, it makes The optical cables inside the first cylinder, the second cylinder and the third cylinder can work stably.

The invention discloses a production method of water-in-water colorful paint containing color sand. The production method comprises the following steps: (a), preparing a protection glue solution; (b), producing basic slurry; (c), matching the color of the basic slurry; (d), performing color point granulation; (e), producing coating gloss oil; (f), producing finished paint. Granite-shaped particle containing particles are formed on the surface of the paint produced by the method, imitated-marble granite paint can be prepared from the paint, formed patterns are simple, artistic and elegant, and the paint prepared by the method is level in surface and not easy to form ash deposition, can keep the overall appearance longer, and has stain resistance; the special coating gloss oil can keep the color on the surface of the paint to be permanent and fresh, and has weather resistance; the paint is high in water resistance and rot resistance, is neither absorbed by a wall surface nor damaged in rainy days, and can protect the overall shapes of buildings.

The invention relates to a high-environment-friendliness concrete aggregate which is prepared from the following raw materials in parts by weight: 100-140 parts of coal gangue detritus, 40-60 parts of casting waste sand, 10-30 parts of nickel slag, 20-40 parts of regenerated diatomite detritus, 3-7 parts of conjugate fibers and 5-9 parts of 0.5 mol / L sodium hydroxide solution. The regenerated diatomite detritus is prepared from the following components in parts by weight: 40-60 parts of pulpous waste diatomite, 20-30 parts of modified steel slag micropowder, 6-10 parts of surface modifier and 0.04-0.06 part of foaming agent. The modified steel slag micropowder is prepared from steel slag and sodium metaborate which accounts for 1 / 10-1-2 of the steel slag. The method detects a direction for large-scale application of coal gangue, casting waste sand, nickel slag, steel slag and waste diatomite, changes wastes into valuable substances, reduces the environmental pollution and land occupation caused by solidified wastes, further utilizes the resources, and implements energy saving and environmental protection. The concrete aggregate has the advantages of high density, low water absorptivity, high strength, low powdering tendency, favorable fire resistance, high weather resistance and wide applicability, and is suitable for popularization.

The invention discloses a nanometer bi-layer film biogas digester material, which is composed of the following components: PVC (polyvinyl chloride) resin, DOP (Dioctyl-Phthalate), DBP (dibutyl phthalate), a stabilizing agent, an antioxidant, an anti-UV (ultraviolet) agent, nano calcium carbonate, modified red mud and other accessory ingredients, wherein the components are subjected to the calendering technology, the fitting technology and the surface treatment technology, and two groups of single-surface surface-treated single-layer biogas digester materials are combined to obtain the bi-layer biogas digester material. The nanometer bi-layer film biogas digester material has the advantages that nano calcium carbonate and the modified red mud are adopted to serve as filling agents, thus the weather resistance, the aging resistance and the like of a PVC film are improved and the service life of the bi-layer film biogas digester material is prolonged; the acrylate coating is used for surface treatment, thus the weather resistance and the aging resistance of the bi-layer film biogas digester material are improved; and because of adopting the bi-layer film structure, the inner-layer film has excellent air impermeability and chemical corrosion resistance, and the outer-layer film has good physical and mechanical property and aging resistance so as to prevent the inner-layer film from being damaged by the external environment.

The invention discloses a high-stability concrete silicone joint glue and a preparation method thereof. The joint glue consists of 100 parts by mass of α,ω-dihydroxy polydimethylsiloxane, 50-150 parts of filler 0.5-10 parts of thixotropic agent, 0.5-10 parts of chain extender, 5-15 parts of curing agent, 0.1-5 parts of tackifier, 0.01-3 parts of catalyst, 1-10 parts of liquid nitrile rubber, First, α, ω-dihydroxy polydimethylsiloxane, thixotropic agent and filler are made into a base material in a kneader, and then the base material is transferred into a high-speed disperser, and the remaining raw materials are added to react to obtain the base material. seam glue. The invention uses liquid nitrile rubber modified silicone joint adhesive, and adopts a specific chain extender to endow the joint adhesive with permanent toughness and mechanical property retention, and the plasticizer does not migrate, does not damage the bonding, and greatly improves Improve the bonding strength, excellent aging resistance, environmental protection and pollution-free.
