Abstract
That the present invention relates to is the preparation method of melamine printed immersion paper, and the selected body paper technical indicator of this method is easy to control.Tableware with this melamine printed immersion paper manufacturing meets national sanitary tableware standard BGn87-80.And the melamine printed immersion paper hot pressing that is printed on trade mark, tag mark can be posted on the thermosetting plastics goods, replace metallic data plate and paste trade mark.
Description
What the present invention relates to is thermosetting resin printed immersion paper, particularly melamine printed immersion paper.
Mentioned among the clear 59-129145 of day disclosure special permission communique at thermosetting plastics product surfaces such as melamines coated with the thermosetting resin impregnated membranes that is printed on decorative pattern, made it to become patterned goods, to improve the value of commodity.The preparation method of this thermosetting resin impregnated membranes is: void ratio is adjusted into 10～20% film, and (this film is generally selected cloth or paper for use, for obtaining having the goods of good appearance, with with paper for well), stamp pattern with methods such as hectograph, silk screen, stamps, impregnated in the thermosetting resins such as melamine resin, the dipping back is carried out drying by drying machine and is formed the semi-solid preparation macerate, cuts on guillotine by required form then and promptly gets thermosetting resin dipping printed film.The empty void ratio of mentioning common paper in this day disclosure special permission communique is the area of micropore part and the ratio of the gross area for the 5%(void ratio), and the void ratio of the used paper of preparation thermosetting resin dipping need be controlled in 10～20% the scope.The void ratio of paper is big, and resin content is big between hole, can improve the cementability between thermosetting resin impregnated membranes and plastic products, when void ratio less than 10%, then adhesive effect is poor, void ratio is greater than 20%, then the fastness of paper film is low, and is easily damaged in the dipping operation, and the pattern after the printing is not bright-coloured yet.For the void ratio of controlling paper 10～20%, need in paper-making process, to adjust void ratio or with the method for pin dense puncture on paper, this work both bothered, and difficulty is bigger.
The objective of the invention is to select for use the existing paper that meets certain technical indicator in market, through printing, dipping melamine resin, drying, operation such as cut, prepared melamine printed immersion paper can replace day disclosed thermosetting resin impregnated membranes of the disclosure special permission clear 59-129145 of communique, this film requires the void ratio of paper 10～20%, and it is bigger to control this index difficulty.
The present invention is achieved in that and at first selects body paper for use that body paper need meet following technical indicator: quantitatively be 25～70 the gram/square metre; Wet strength is not less than 1 newton; Dry strength is not less than 20 newton; Suction head is not less than 5 millimeters; Ash is not more than 0.4%(weight).The paper that meets above-mentioned technical indicator, quality is loose, has certain intensity again, is easy to printing and impregnating resin.
After body paper is made, pattern is printed on the body paper with offset printing method.The used printing ink sun-proof grade of hectographic printing is three grades, 150 ℃ of heatproofs, and nondiscolouring, unfading in PH4～9 scopes, the carrier of printing ink itself is a thermosetting resin, as amino resins, phenolic resins etc.
After pattern is printed, the melamine resin liquid for preparing is painted on the paper equably, makes it to soak into.Melamine resin liquid is preparation like this: add formalin earlier, regulate PH to 6.0～8.0 with PH conditioning agent methenamine, add melamine then, the mol ratio of melamine and formaldehyde is 1: 1.6～3.0, heat up gradually, under 70～80 ℃, react transparent,, determine reaction end by measuring its turbidity to solution.The assay method of cloud point is to splash into 1 part of resin liquid to be measured in 3 parts 40 ℃ water, and the muddiness circle when resin liquid is white in color in 40 ℃ of water did not disappear in 20 seconds, illustrates that then resin reaction has reached terminal point.After reaching home, the solution pH value is adjusted to 7.0～9.0, and adds the mixture of used usually curing agent ethyl oxalate, ammonium chloride or these two kinds of curing agent, the content of curing agent in melamine resin liquid is 0.3%(weight) about.With add water or vacuum dehydration with the resin content in the control melamine resin liquid in 25～70%(weight).
The body paper that is printed on pattern just carries out drying behind impregnating resin, baking temperature is 50～150 ℃, and decide according to baking temperature drying time, the temperature height, and the time can lack, and temperature is low, and the time can be grown, and drying time is generally at 15 minutes to 2 hours.Dried melamine printed immersion paper cuts the back packing on request, and resin content is 30～80% in the prepared melamine printed immersion paper.The impregnating resin operation can be once, also can impregnation drying after, dipping is once again.The advantage of flooding twice is that the distribution of melamine resin in the melamine printed immersion paper is than once more even of dipping.
The invention has the advantages that the selected body paper technical indicator of melamine printed immersion paper is easy to control, the void ratio that needn't require paper is in 10～20% these unmanageable indexs, saved to adjust void ratio in the paper-making process or with pin this complex steps of dense puncture on paper.The body paper of selecting for use with the present invention is a carrier, through dipping melamine resin, drying, the prepared melamine printed immersion paper of operation such as cut, can replace day disclosed thermosetting resin impregnated membranes of the disclosure special permission clear 59-129145 of communique.The melamine printed immersion paper that the present invention makes, with melamine plastics goods such as melamine molding compound, the prepared melamine printed tableware of melamine light-shielding resin matched moulds hot pressing, melamine printed ceramic tile, melamine printed vases, bright in luster, clear patterns, colour-fast, indeformable, do not ftracture, can anti-boiling water and-20 ℃ of low temperature, product meets national sanitary tableware standard GBn87-80.With melamine printed immersion paper and amino film plastics, the artistic ornament that the hot pressing of phenolaldehyde moulding compound matched moulds gets, inexpensive, the decorative pattern difficult drop-off.To be printed on duroplastic moulding materials matched moulds hot pressing such as the melamine printed immersion paper of trade mark, label symbol and amino film plastics, phenolaldehyde moulding compound, make its thermosetting plastics goods have trade mark, label symbol, replace metallic data plate or paste label paper, prevent counterfeit goods, metallic data plate and stickup label paper easily take off transposing, easily personation.
