The invention discloses a multi-functional laminated iron production line. The multi-functional laminated steel production line comprises a cold rolled base plate unwinding device, a seam welder, two S turning roller sets, a first or/and second thin film release device, an iron sheet laminating device and a laminated iron winding machine, which are sequentially arranged in a conveying direction of metal base plates; the metal base plate from the seam welder enters the iron sheet laminating device after being tensioned and rectified, and a first thin film or/and second thin film is/are fed into an iron sheet laminating machine after rectification, so that the iron sheet laminating machine covers one surface or two surfaces of the metal base plate with the first thin film or/and the second thin film to form single-sided or double-sided laminated iron, the single-sided or double-sided laminated iron is fed into the other S turning roller set by the iron sheet laminating machine to be tensioned, and the tensioned single-sided laminated iron is wound by the laminated iron winding machine. The multi-functional laminated iron production line can produce both low-temperature bonded laminated iron and high-temperate melted laminated iron, is advanced iron laminating equipment capable of realizing efficient and continuous production, and can be well adaptive to the change of market requirement.

The invention provides a preparation method of a superabsorbent resin used for a high-molecular gel extinguishing agent. The preparation method comprises: mixing acrylic acid and a sodium carbonate aqueous solution to prepare a neutralization solution; successively adding a cross-linking agent, an initiator and an adhesion promoter into the neutralization solution to prepare a polymerization solution; performing polymerization to prepare the superabsorbent resin; and cutting into particles with a diameter of 10-20 mm to further prepare superabsorbent resin particles with a particle size of 40-150 meshes. The preparation method is simple, and the superabsorbent resin prepared by the method is convenient to used and excellent in fire extinguishing effect.

The invention discloses a preparation method of nucleocapsid soap free surface sizing agent and comprises the following procedures that: (1) firstly, water, macromolecule polymers and monomers are mixed according to the mass ratio of 8.5:1.5 to 6.5:3.5, then proper molecular weight regulator are added and uniformly stirred; the monomers comprise a function monomer, an acrylate kind soft monomer, a hard monomer and an ion monomer; (2) in a stirring state, a part of mixture which accounts for 10 percent to 60 percent of the total mixture mass of the acrylate kind soft monomer, the hard monomer and the ion monomer is added and heated to 73 to 75 DEG C; evocating agent solution which accounts for 20 percent to 50 percent of the total evocating agent mass is then added; after 20 to 60 minutes, the mixture is heated to 76 to 82 DEG C; (3) then the residual mixture of the acrylate kind soft monomer, the hard monomer and the ion monomer and the residual evocating agent solution are respectively added; (4) the mixture is heated to 80 to 82 DEG C for heat preservation, has reaction for 2h to 3h, cooled to the room temperature and filtered, thereby achieving the nucleocapsid soap free surface sizing agent.

The invention discloses a preparation method of a salt-resistant and detergent-resistant seaweed fiber; by introducing an auxiliary agent containing a borate radical, a finished product seaweed fiber is contacted and infiltrated with an auxiliary agent solution, appropriate raw materials, proportion and reaction conditions are selected, and thus the salt-resistant and detergent-resistant seaweed fiber is prepared. The preparation method solves the problems that the seaweed fiber and textiles thereof are not resistant to salts and detergents; the seaweed fiber after being modified by the borate radical and textiles thereof have good salt resistance and can withstand washing of alkaline detergents; the seaweed fiber modified by the auxiliary agent solution enables the swelling degree to be reduced to 39.8% after being soaked for 72 h in 30 DEG C normal saline, and enables the swelling degree to be reduced to 55.3% after being soaked for 24 h in a standard detergent; and the original appearance of the fiber is maintained, no obvious dissolution phenomenon generates, and at the same time, the self flame retardant performance of the seaweed fiber can be maintained.
