Description

A kind of high-performance frit for porcelain enamel

Technical field

The present invention relates to a kind of frit for porcelain enamel.

Background technology

Frit for porcelain enamel be for the application of slip at the metal mold, consist of the glass state material of alkali-boron-silicate.It had both had the intrinsic physical strength of metal and processing characteristics, have again that the figure layer has corrosion-resistant, wear-resisting, heat-resisting, nontoxic and can be ornamental.It is widely used in the daily life, such as tableware, kitchen tools, wall, floor etc.

Summary of the invention

Technical problem to be solved by this invention provides a kind of high-performance frit for porcelain enamel, and this frit for porcelain enamel has difficult drop-off, wear-resisting, corrosion resistant advantage.

Technical problem to be solved by this invention is achieved by the following technical programs:

A kind of high-performance frit for porcelain enamel is comprised of the component of following mass percent:

Quartz 30 ~ 40%, borax 20 ~ 30%, SODIUMNITRATE 3 ~ 8%, calcium oxide or barium oxide or Lithium Oxide 98min 5 ~ 10%, sodium oxide 2 ~ 5%, aluminium sesquioxide 2 ~ 5%, boron oxide 2 ~ 5%, polyethylene wax powder 1 ~ 3%, Calcium Fluoride (Fluorspan) 3 ~ 8%, nickel oxide 1 ~ 3%.

Further, each component and mass percent are preferably:

Quartz 35%, borax 25%, SODIUMNITRATE 5%, calcium oxide 10%, sodium oxide 5%, aluminium sesquioxide 5%, boron oxide 5%, polyethylene wax powder 2%, Calcium Fluoride (Fluorspan) 5%, nickel oxide 3%.

The present invention has following beneficial effect:

Glaze sticking power of the present invention is good, wear-resisting, corrosion-resistant.

Embodiment

The present invention will be described in detail below in conjunction with embodiment, and embodiment only is preferred implementation of the present invention, is not limitation of the invention.

A kind of high-performance frit for porcelain enamel is comprised of the component of following mass percent: quartzy 35%, borax 25%, SODIUMNITRATE 5%, calcium oxide 10%, sodium oxide 5%, aluminium sesquioxide 5%, boron oxide 5%, polyethylene wax powder 2%, Calcium Fluoride (Fluorspan) 5%, nickel oxide 3%.

The preparation method of this frit for porcelain enamel is: each raw material fully pulverized, mixed, drop in the crucible, and fusing under 1200 degree, then cold quenching in cold water is pulled oven dry out, solidifies to get block frit.The preparation method is this area general knowledge, is not described in detail.

Above-mentioned frit for porcelain enamel is made enameling sheet take stainless steel plate as matrix, carry out the detection of tack, wear resistance, erosion resistance.

(1) adhesion test method is:

Mark the lattice (scratch depth is controlled at and guarantees film lower substrate metal exposed) of 100 1mm of being spaced apart of uniform size with sharp blade on the enameling sheet surface, the lattice that the ketone group glaze comes off is counted N1, the scotch tape that width is 24mm is sticked in the lattice zone of drawing on film, and guarantees between adhesive tape and the film that grid is arranged in conjunction with tight.Behind the 5min, with the power of a vertical face adhesive tape is uncovered, and is again added up the lattice that film comes off and count N2.Appraisal procedure is as follows: adopt centesimal system, film sticking power mark=100-(N1+N2), film sticking power mark is larger, illustrates that sticking power is better.

(2) abrasion resistance test method is:

Enameling sheet put into take out after 2h is ground in oscillating mill continuous shaking, whether the rete of observing the corner angle of enameling sheet and surface has comes off.

(3) erosion resistance testing method:

Weigh by salt-fog test, the salt-fog test method is for to place enameling sheet in the salt-mist corrosion tester, 35 the degree under with 5% sodium chloride aqueous solution splash 2h after, taking out and being placed on another temperature again is that 40 degree, relative humidity are in 80% the climatic chamber, how long the rear surface occurs unusual to observe it, time is longer, illustrates that the erosion resistance of rete is better.

Test-results is as shown in table 1.

Film sticking power mark	Wear resistance	Erosion resistance (lab scale)
			100	Corner angle and surface are all without any coming off	240

As can be seen from Table 1, the board with enamel panel layer made of frit for porcelain enamel of the present invention has good sticking power, wear resistance and erosion resistance.
