Abstract
The invention discloses a kind of volatile rust preventive paper and production method thereof, concrete system adopts the anti-wrinkling neutral kraft paper of energy absorption value (T.E.A) 〉=500 of opening as base material, at the compound PE film of the one side of wrinkling neutral kraft paper, do not contain the vapour phase inhibitor of nitrite in the another side coating of wrinkling neutral kraft paper.The producer genealogy of law of this anti-tarnish paper is formed the vapor phase corrosion inhibitor agent prescription by raw materials such as capric acid and dimethylethanolamine, benzoic acid, deionized water or distilled water, be applied to by 10g/ square metre (amount of giving money as a gift) on 70g/ square metre the wrinkling neutral kraft paper, another side at wrinkling brown paper is compounded with the PE film, and semi-finished product are dried to moisture about 10% in 20-100 ℃.
Description
The present invention relates to a kind of volatile rust preventive paper and production method thereof.
Iron and steel generally all need carry out corrosion protection in transporting procedures handles, and traditional method is that this method need consume grease at metal surface coating corrosion protection grease, during use, must carry out the degrease operation again.In recent years, people have developed the vapor phase metal anti-tarnish paper, and this anti-tarnish paper only need be attached to the surface that needs non-corrosive metal (NCM), and can make needs non-corrosive metal (NCM) at certain hour (for example 7 cycles) non-corrosive.But these anti-tarnish papers or toughness are relatively poor, in use produce breakage, or contain nitrite, in use can cause the generation of nitrosamine.
The purpose of this invention is to provide a kind of volatile rust preventive paper and production method thereof that does not contain nitrite, have splendid toughness by corresponding anti-tarnish paper provided by the invention, and the antirust cycle that can corresponding prolongation anti-tarnish paper.
(if no special instructions, following umber for by weight) that the objective of the invention is to be achieved by following technical solution:
At first 16.5 parts of capric acid and 8.5 parts of dimethylethanolamines are mixed in 60-70 ℃, in addition 14.5 parts of benzoic acid and 10.5 parts of dimethylethanolamines are mixed, two kinds of mixtures are pressed (40-60%): weight ratio (60-40%) mixes, add deionized water or distilled water then by a certain percentage, and by per 100 parts of mixtures interpolation 0.1-0.2 part NaOH, the adjusting pH value is 7-9, promptly constitutes vapour phase inhibitor.
Dimethylethanolamine in the above-mentioned corrosion inhibiter can be substituted by diethyl ethylene diamine or diisopropyl ethanolamine, also can adopt the wherein tertiary amine mixture replacing of two kinds or three kinds components, tertiary amine general molecular formula (CnH2n+1) 2 NCH2CH2OH(n=1-3 that adopted).But its molal quantity should be corresponding with described tertiary amine.
Benzoic acid in the above-mentioned corrosion inhibiter can be substituted by methyl salicylic acid, salicylic acid or Aminosalicylic, also can adopt tert-butylbenzene formic acid to substitute.Or adopt and to contain the wherein mixture replacing of component more than two kinds or three kinds, but its molal quantity should be consistent with the benzoic acid molal quantity during prescription is formed.
Neutral kraft paper through wrinkling processing, is controlled percentage elongation: vertically 〉=22%;
Control tearability: more weak direction: 1500-1810mN or 〉=1810mN;
The anti-energy absorption value (T.E.A) of opening of control
Vertically 〉=500.
The compound PE film of the one side of the wrinkling neutral kraft paper after processing, be coated with the vapour phase inhibitor for preparing at another side, coating weight is applied to by 10g/ square metre (amount of giving money as a gift) on 70g/ square metre the wrinkling processing brown paper, be dried to moisture about 10% in 20-100 ℃, promptly get desired volatile rust preventive paper.
Because the present invention has adopted technique scheme, thereby can guarantee that anti-tarnish paper has splendid toughness, and can prolong the antirust cycle of anti-tarnish paper at double.
Because vapour phase inhibitor of the present invention does not contain nitrite, thereby fundamentally eliminated the factor that produces inferior ammonium nitrate.
Describe the present invention in detail below in conjunction with embodiment.
(if no special instructions, following umber all by weight)
A, 16.5 parts of capric acid and 8.5 parts of dimethylethanolamines are mixed in 60-70 ℃, in addition 14.5 parts of benzoic acid and 10.5 parts of dimethylethanolamines are mixed, two kinds of mixtures are pressed (40-60%): weight ratio (60-40%) mixes, in mixture and deionized water or distilled water is (40-60%): ratio (60-40%), mixture and deionized water (or distilled water) are mixed, add 0.1-0.2 part NaOH by per 100 parts of mixtures, the adjusting pH value is 7-9, promptly constitutes vapour phase inhibitor.
Dimethylethanolamine in the above-mentioned corrosion inhibiter can be substituted by diethyl ethylene diamine or diisopropyl ethanolamine, also can adopt the wherein tertiary amine mixture replacing of two kinds or three kinds components, tertiary amine general molecular formula (CnH2n+1) 2 NCH2CH2OH(n=1-3 that adopted).But its molal quantity should be consistent with the molal quantity of described dimethyl ethanol ammonium.
Benzoic acid in the above-mentioned corrosion inhibiter can be substituted by methyl salicylic acid, salicylic acid or Aminosalicylic, also can adopt tert-butylbenzene formic acid to substitute.Or adopt the wherein mixture replacing more than two kinds or three kinds, but need make the molal quantity of substitute consistent with the benzoic acid molal quantity that is adopted.
B, with neutral kraft paper through wrinkling processing, control percentage elongation: vertically 〉=22%;
The control tearability:
More weak direction: 1500-1810mN or 〉=1810mN;
The anti-energy absorption value (T.E.A) of opening of control
Vertically 〉=500.
The compound PE film of the one side of the wrinkling neutral kraft paper after processing, be coated with the vapour phase inhibitor for preparing at another side, coating weight is applied to by 10g/ square metre (amount of giving money as a gift) on 70g/ square metre the wrinkling processing brown paper, be dried to moisture about 10% in 20-100 ℃, promptly get desired volatile rust preventive paper.
Volatile rust preventive paper of the present invention can attach the packing iron and steel, also can directly pack main equipment, empirical tests, and its rust-proof effect excellence to general iron and steel test piece, adopt to be interrupted the heating test, can guarantee corrosion not to take place in 300 hours, occupies the leading level in the world.
Volatile rust preventive paper toughness of the present invention is splendid, and normal the use can prevent paper sheet break fully.
