Abstract

The wall electrostatic spinning be utilize high voltage electric field will be through electricity the fibre fluff handled be implanted on the wall that scribbles adhesive.Its technology contents comprises the development that adhesive and fine hair electricity inorganic agent, the technology of wall flocking and the design of electrostatic flocking apparatus.The advantage of wall flocking is that the flocking fastness is good, lovely luster, and gloss is soft, and heat insulation sound absorbent is durable in use, and flame retardant effect is arranged, and is convenient to clean, and is particularly useful for high-grade interior decoration.

Description

Electrostatic flocking method on wall

The present invention is a kind of new electrostatic flocking method on wall, belongs to building field.Its main contents relate to the adhesive of flocking, and the electricity of fine hair processing, wall flocking technique, special maneuver and the equipment of flocking.The unresolved always subject matter of technology of direct flocking has two problems on wall for a long time.

The first, used adhesive is the price height not only, and the flocking fastness is poor, and the conjunctiva of adhesive is fast, and fibre fluff is difficult for inserting glue-line during flocking, or the degree of depth of insertion glue-line is superficial, and the flocking fastness is poor, does not perhaps plant at all.

The second, do earth polar (positive pole) as the wall of flocking, electric conductivity is very poor, therefore between wall and flocking plant (negative pole), be difficult for forming strong high voltage electric field, the consumption of fine hair is big, makes the magnetic line of force strength deficiency of fine hair insertion glue-line, influences the uniformity of flocking fastness and flocking.

Purpose of the present invention is exactly to solve the above problem that exists:

Thermoplastic resin is (as vinyl acetate-acrylate copolymer emulsion, vinyl acetate-chloroethylene copolymer emulsion, vinyl acetate-ethylene copolymerization emulsions) 100, thermosetting resin (phenolic resins, or trimerization ammonium resin, the HMM resin) 1-5%, ammonium salt class conductive agent 0.15-1%, antistatic additive SN 0.15-1.5%, conjunctiva prolong agent acrylates 1-3%, acrylic thickener ASE-60 0.5-1.5%, the viscosity of this adhesive requires 6000-10000cps.

The second, adopt fine hair inorganic agent based on aluminium colloidal sol, its prescription is as follows:

Aluminium colloidal sol 4-8%, antistatic additive Tm0.5-1.5%, 30% Ludox 5-15%, ammonium chloride 4-6%, the molten ratio of fine hair weight and water 1: 16 adds various compositions and handled 15-30 minute under temperature 40 degree conditions.

The 3rd, according to the characteristics of wall electrostatic spinning, formulate rational technology.Technological process comprises the repairing metope, prevents that the Flock Adhesive infiltration is coated with primer, is coated with Flock Adhesive, electrostatic spinning and the floating hair of removing etc.Gluing thickness 0.3-0.4mm wherein, die opening 90-140mm(just plants 150-250mm), ten thousand volts of voltage 5.5-6, the floating hair of cleaning after 24 hours after the flocking, one week back finish-drying and crosslinked.

With the wall flocking that the present invention obtained, superior in quality, dry grinding fastness more than 2000 times, wet-milling fastness be more than 150 times, and certain flame retardant effect is arranged.Because the fine hair of flocking is mainly used nylon and acrylic fibers (length 0.5-0.8mm, fineness 1.5-3D), lovely luster, gloss is soft, heat insulation sound absorbent, it is convenient to clean.The wall electrostatic spinning has become a kind of interior decoration technology of novelty.

The wall electrostatic spinning is to use electrostatic flocking apparatus fine hair is implanted on the wall that scribbles adhesive.Electrostatic flocking apparatus mainly comprises: screen cloth, dress suede device, electrode and handle four parts.Can keep a certain amount of fine hair in the container, the direction that fine hair is pressed the magnetic line of force through hyperpolarization flies to wall by screen cloth.Selected mesh density and area can be controlled out the suede amount and divide comb fine hair.

The electrostatic flocking apparatus accompanying drawing in after.Wherein

The 1-copper mesh;

2-dress suede device;

The 3-electrode;

4, the 5-insulating slab;

6-electrode hold-down nut;

7-organic glass handle.

Claims

1, a kind of new electrostatic flocking method on wall is primarily characterized in that a kind of new adhesive, and the fine hair electricity inorganic agent, wall electrostatic flocking apparatus and technology.
