Abstract

The ordinary-temp. far infrared radiation paint used for health-care appliances, ceramic heater and metallic heater for far infrared heating from ordinary temp. to high temp. is made of hematite ore, metallic and non-metal oxides, and inorganic adhesive of silicates or phosphates, and features low cost and simple preparing process.

Description

A kind of normal temperature coatings capable of preventing from far infrared radiation

The present invention relates to a kind of manufacture method of coatings capable of preventing from far infrared radiation, this coating is widely used in department's normal temperature such as worker, agricultural to medium and high temperature section far infrared heating technology field.

General coatings capable of preventing from far infrared radiation all adds a certain amount of silicate or phosphate inorganic adhesive and makes.No. 86106391, Chinese patent application, a kind of manufacture method of coatings capable of preventing from far infrared radiation is disclosed, calcination clay, manganese oxide, nickel oxide, zirconium white difference grinding powder are screened several times with 200 purpose sieves, the powder that sieve is good mixes the back at normal temperatures and adds mineral binder bond, make far ultrared paint, its manufacturing process complexity, the cost height.The manufacture method that Chinese patent application discloses a kind of coatings capable of preventing from far infrared radiation No. 89105088.4, with the metallurgical industry copper ashes is main raw, add ferric oxide, manganese oxide, chromic oxide, nickel oxide, cobalt oxide, behind ball milling, add mineral binder bond at normal temperatures and make.Because the copper ashes source is few, the raw material supply difficulty.Though and above two kinds of coating total radiation rates all are not less than 0.91, and are poor with the Wavelength matched property of far infrared rays, cause window little, are difficult to reach the ideal effect.

The purpose of this invention is to provide that a kind of material source is extensive, cheap, complete processing is simple, the total radiation rate is high and with the manufacture method of the good normal temperature coatings capable of preventing from far infrared radiation of the Wavelength matched property of far infrared rays.

The present invention is achieved in that the rhombohedral iron ore stone with cheapness is main raw material, is aided with manganese oxide, cupric oxide, aluminum oxide, cobalt oxide, zinc oxide, nickel oxide, titanium oxide, magnesium oxide, silicon oxide and silicate or phosphoric acid salt mineral binder bond and forms.Wherein rhombohedral iron ore stone is through behind the ball milling with the per-cent that cooperates of oxide compound component more than seven kinds being: rhombohedral iron ore stone 55-70%, manganese oxide 9-13%, cupric oxide 1.5-3.5%, aluminum oxide 2.5-4.5%, cobalt oxide 0.5-2.5%, zinc oxide 2.5-3.5%, nickel oxide 1.5-2.5%, titanium oxide 0.5-3.5%, magnesium oxide 2.5-3.5%, silicon oxide 8-15%, and the silicate of weight such as adding or the aqueous solution of phosphoric acid salt mineral binder bond, wherein binder content is 35-85%.

Each component is weighed respectively in proportion in will filling a prescription, and earlier rhombohedral iron ore stone is put into ball mill in proportion, pulverizes after adding entry.When the sampling Detection fineness reaches 250 orders, again by ball milling behind other each components of prescription adding.When the sampling Detection fineness reaches 320 orders, can go out mill.With mill back filler add connect need preparation etc. the adhesive solution of weight, stir at normal temperatures and can use.

Embodiments of the invention 1, weight cooperate per-cent to be: rhombohedral iron ore stone 55%, manganese oxide 13%, cupric oxide 3.5% aluminum oxide 4.5%, cobalt oxide 2.5%, zinc oxide 3%, nickel oxide 2.5%, titanium oxide 3.5%, magnesium oxide 3.5%, silicon oxide 9%.Contain silicate 85% in the adhesive solution.

Embodiments of the invention 2, weight cooperate per-cent to be: rhombohedral iron ore stone 70%, manganese oxide 9%, cupric oxide 1.7%, aluminum oxide 3%, zinc oxide 2.5%, titanium oxide 0.8%, cobalt oxide 1%, silicon oxide 12%.Phosphorous hydrochlorate 35% in the adhesive solution.

The present invention tests through infrared product inspection center of country, record total radiation rate value such as the table 1 of embodiment 1: temperature (℃): 150 300 500 700 836 normal emittances: 0.87 0.88 0.88 0.88 0.88 provides wavelength 2.5-13.5 μ M, after coating was born the impact of 2000g.cm, flawless, nothing were peeled off.Be applied to total radiation rate value such as table 2 that health-care product and ceramic heating aspect record embodiment 2: temperature (℃): 150 300 500 700 836 normal emittances: 0.87 0.88 0.87 0.86 0.87 provides wavelength 2.5-13.5 μ M, after coating was born the impact of 2000g.cm, flawless, nothing were peeled off.Be applied on the metal heat-generating pipe device.

The present invention compared with prior art has the following advantages: raw material wide material sources, valency Lattice are cheap; To the medium and high temperature section, total radiation rate and far infrared are Wavelength matched at normal temperature, Emissivities are strong, obvious energy conservation; Manufacturing process is simple.
