The invention discloses a phase change heat storage type electric heating floor. The phase change heat storage type electric heating floor comprises a floor main body and an electric heating assembly. Socket positions which are connected with the adjacent electric heating floor portions during usage are formed on the periphery of the floor. The phase change heat storage type electric heating floor is characterized by also comprising a flat phase change unit; the floor main body comprises a panel component and a base plate; the corresponding positions of the panel component and the base plate in the vertical direction are bonded and fixed together to form the floor main body, wherein the inside of the floor main body comprises the first installation space; the electric heating assembly comprises an electric heating piece, a transmission unit and connection sockets which are located at the front end and the rear end of the electric heating piece respectively and used for performing electrical connection externally; the electric heating piece and the phase change unit are fixedly arranged in the first installation space of the floor main body; the panel component, the electric heating piece, the phase change unit and the base plate are arranged in turn from top to bottom and are in close contact with each other in turn in the vertical direction.

The invention discloses an environmentally-friendly organic inorganic hybridized paint and preparation method and application thereof. The preparation method includes that acrylosilane microemulsion is taken as binder, 2-35 parts of acrylosilane microemulsion containing hydroxyl is dissolved into 10-80 parts of alcohols solvent, 1-15 parts of tetraethoxysilane, 2-30 parts of organosiloxane and 0.5-10 parts of basic catalyst are added, hydrolysis and polycondensation are carried out in organic polymer emulsion to form hydrophobic inorganic network, so as to obtain organic inorganic hybridized acrylosilane paint. The paint is coated on the surface of water poly(methyl) acrylic ester primer and is dried, thus obtaining the organic inorganic hybridized super-hydrophobic coating with favourable mechanic performances. The adhesive force of the super-hydrophobic coating can achieve 1-2 level, water static contact angle is more than 150 degrees, and rolling angle is less than 10 degrees. The invention is simple in technology, available in raw materials and low in cost and overcomes the defects of the existing preparation technology and the disadvantage of poor mechanical performances of the super-hydrophobic coating.

The invention discloses a preparation process of a fluffy, warm, mildew-proof down quilt. The filled down fibers are first pretreated to remove impurities and dust on the down, and then the down fibers are modified to introduce bactericidal and antibacterial active N+ into the down quilt. In the down fiber, the pre-modified down fiber is mixed with metal ions, and the phenolic and alcoholic hydroxyl groups on the pre-modified down fiber can be combined with Ni 2+ and Fe 3+ Complexation further improves the antibacterial and antifungal performance of down fiber. In addition, Ni 2+ and Fe 3+ It has better far-infrared radiation ability, and it is introduced into the down fiber, thereby improving the warmth retention of down, Ni 2+ and Fe 3+ Introduced into the down fiber to generate electrostatic effect, which can improve the bulkiness of down; this process is scientific and reasonable, and improves the defect that the existing down fiber is not mildew-proof, and after repeated washing, it still has good anti-bacteria and anti-mold properties. The prepared duvet has good washability.

The invention provides a water-based ink emulsion resin and a preparation method thereof. Through a specially optimized emulsification scheme and process control, the emulsion polymerization process of the invention is stable and controllable, and there is no filter residue after the reaction, which solves the problem of high acrylonitrile monomer content. The problem of emulsion polymerization stability, the particle size of the emulsion of the present invention is fine, and the particle size distribution is very narrow, which is beneficial to the configuration of the subsequent gravure printing water-based ink, the emulsion has strong adhesion fastness to the ASA / ASA composite system, and the blank film sample The peel strength of the film is increased to more than 2 times, and the PVC / PVC composite system also has good adhesion performance, and the peel strength of the blank film sample can be raised to nearly 2 times. The fine particle size emulsion resin of the present invention is expected to be applied to ASA Preparation of water-based ink for gravure printing on plastic film or PVC furniture film.

The invention discloses a self-heating type floor decoration brick, and is characterized by comprising a floor tile panel, a floor tile lower seat and a self-heating assembly. A heating unit of the self-heating assembly is an electric heating piece. The floor tile is stuck and fixed above the floor tile lower seat to form a floor tile main body provided with an inner cavity. The electric heating piece of the self-heating assembly is arranged in the inner cavity of the floor tile main body. Power supply plug connectors of the self-heating assembly are arranged on the front side and the back side of the floor tile main body. The power supply plug connectors are reliably limited and fixed in the floor tile main body and can be used for electric connection with an adjacent electric heating floor tile and transmission of current by externally protruded spliced eye positions provided with copper contain pins through corresponding electric connection assemblies, so that the electric heating floor tile has the advantages of being simple and convenient to install, safe and reliable to use, higher in heat efficiency, durability and structurally providing technical supports.
