The invention provides a flame-retardant bark of an artificial tree and a making method thereof. The bark is prepared from the following raw materials: epoxy resin, polyaniline, carboxyl polysiloxane, heavy calcium carbonate powder, fumed silica, pigment printing paste, glass fiber, a curing agent, a fire retardant, dibutyl phthalate and a mixed solvent. The making method comprises the following steps: adding epoxy resin into a reaction vessel, then adding the mixed solvent for dissolving, adding polyaniline into the reaction vessel, mixing polyaniline with mixing under high-speed stirring, carrying out a reaction at 20 to 25 DEG C for 1 h with a pH value controlled to be 1 and then adding carboxyl polysiloxane; continuing the reaction at a temperature in a range of room temperature to 50 DEG C for 2 to 5 h; and then adding dibutyl phthalate, heavy calcium carbonate powder, fumed silica, pigment printing paste, glass fiber, the curing agent and the fire retardant, carrying out uniformly mixing under stirring, pouring the obtained mixture into a bark die placed in advance and carrying out micro-pressure standing so as to eventually obtain the flame-retardant bark of the artificial tree. The bark of the artificial tree has lifelike texture and flame retardation effect.

Provided are a door made of environmental-protection and energy-saving fireproof composite plates and a production method. Fireproof doors at the market are steel fireproof doors and wood fireproof doors, wherein the steel fireproof doors are usually made of steel plates with rock wool or expanded perlite filled inside. The production method of environmental-protection and energy-saving fireproof composite plates includes the following two steps: producing flame retardant single plates by aid of pure solid wood; arraying the flame retardant single plates in a way of placing one layer of longitudinal texture single plates and then placing one layer of transverse texture single plates crossly. The production method is used for producing the door made of the environmental-protection and energy-saving fireproof composite plates.

The invention relates to a home building material, in particular to a cabinet board and a manufacturing method thereof. The cabinet board structurally and sequentially comprises a decorative paper, a moisture-proof board and a shaving board from top to bottom, wherein an aluminum alloy is used for braiding the circumference of the cabinet board, an anti-flaming low formaldehyde emission UF resin adhesive is coated between the moisture-proof board and the shaving board and the shaving board in the cabinet board is glued by the adhesive. The cabinet board provided by the invention is high in bonding strength and low in formaldehyde emission, and has flame retardant property and environmental protection; furthermore, most raw materials are residual waste materials of woods, therefore the cabinet board is low in price and low in economical cost, and belongs to the recycling of regenerative resources.

According to the present invention, the aqueous thin coating type aluminum alloy fireproof coating material has advantages of uniform fineness, high bonding strength, long flame retardant time, good weather resistance, thin coating, environmental protection and the like; and the preparation method has characteristics of simple process, high production efficiency, stable product quality and environmental friendliness.

The invention discloses a crosslinked polyethylene insulating fireproof flame-retardant power cable in the technical field of cables. The cable comprises a copper conductor, and the outer wall of thecopper conductor is sleeved by an insulating layer. The outer wall of the insulating layer is sleeved by a shielding layer. The outer wall of the shielding layer is sleeved by a flame-retardant layer,and a heat conduction frame is arranged in the flame retardant layer. The heat conduction frame comprises ferrules, and the ferrules are uniformly arranged in the flame-retardant layer, wherein a connecting rod is welded between the ferrules. Through holes are formed in the outer walls of the ferrules and the connecting rod, and the outer wall of the flame-retardant layer is sleeved by a mineralinsulating layer, wherein the outer wall of the mineral insulating layer is sleeved by an outer protective sleeve. According to the cable, the heat conduction frame is arranged in the flame retardantlayer; when the cable encounters a fire, the local flame-retardant layer is heated to enable the heat conduction frame to be heated to conduct heat, the flame-retardant layer at the heated heat conduction frame is heated to decompose water vapor, the water vapor moves towards the burning damage position of the cable due to pressure, the flame-retardant time of the flame-retardant layer is effectively prolonged, and the normal power-on time of related alarm and safety indication equipment is effectively prolonged.

The invention discloses coating solid magnesium desulfurizer and a manufacture method thereof; the coating solid magnesium desulfurizer is made of following components in weight percentage: (1) 94 to97 percent of metal solid magnesium, 1 to 4 percent of magnesia powder, 0.1 to 1.0 percent of graphite powder, 0.5 to 1.5 percent of chloride, 0.1 to 0.5 percentof selenious acid and 0.2 to 0.6 percent of silicone grease; (2) components producing process is as follows: raw material - mix - agitation - response - adding package agent - dry -screen separation - finished product; earthy graphite powder, magnesia, chlorine salt, selenious acid and silicone grease are adopted as the composition and such producing technical solution is adopted as from raw material - mix - agitation - response - adding package agent - dry - screen separation - finished product. The method overcomes such flaws exiting in the prior coating solid magnesium desulfurizer as surface hygroscopicity and agglomeration ofthe solid magnesium, inconvenience for transportation and storage, lance sticking, jammed and splattering in the process of spraying and blowing, a plurality of used cerium oxide, expensive price, badeffect of formaldehyde on human heath and environment pollution, etc. The coating solid magnesium desulfurizer and the manufacture method are widely applied in molten iron pre-desulphurization and molten steel deepening desulphurization production in steel and iron smelting industry.
