Abstract
The present invention relates to an impregnating phenol-formaldehyde resin for producing paper high-pressure decorative fire-resisting plate and its production process. Its formula composition includes (by weight portion) melamine 210-280, phenol 250-350, formaldehyde 450-550, methyl alcohol 480-560 and ammonia water 20-40, besides, 4-6 portions of water and 1.8-2.2 portions of flake alkali also can be added. Its production process includes the following steps: (1). adding phenol, formaldehyde and ammonia water in reaction still, regulating pH value; (2). adding melamine, heating, when the water solubility reaches to 100%, stopping reaction; (3) adding methyl alcohol, stirring, natural cooling and discharging material. In the above-mentioned process the alkaline water also can be added.
Description
Technical field
The present invention relates to a kind of resol and production technique thereof, decorate the impregnated phenolic resin and the production technique thereof of PLASTIC LAMINATED in particular for the papery high pressure.
Background technology
Along with the develop rapidly of building decorating industry, the application that high pressure is decorated PLASTIC LAMINATED obtains unprecedentedly popularizing.But existing production high pressure is decorated the used resol of PLASTIC LAMINATED, its main component is a phenol, cost height not only, and after adopting high-load phenol to make resol, volatile component is more, be used for behind the upholstery the yet corresponding raising of the pollution of room air is not met the trend of modern society's " healthy, long-lived, comfortable ".
Summary of the invention
Technical problem to be solved by this invention provides the improvement of a kind of resol and production technique, and this product should have that phenol content is few, cost is low, the characteristics of safety and environmental protection, and production technique has that flow process is simple, the characteristics of easy handling.
Technical scheme provided by the invention is: a kind of papery high pressure is decorated the PLASTIC LAMINATED impregnated phenolic resin, and the weight part of each contained composition is in its prescription: trimeric cyanamide 210-280, phenol 250-350, formaldehyde 450-550, methyl alcohol 480-560, ammoniacal liquor 20-40.
The composition and the weight part that also can add in this resin are: water 4-6, sheet alkali 1.8-2.2.
The weight part of each composition that this resin is contained is: water 5, sheet alkali 2, trimeric cyanamide 235, phenol 294, formaldehyde 470, methyl alcohol 510, ammoniacal liquor 25.
The production technique of this resin is:
One, stir drop into phenol, formaldehyde in reactor after, add ammoniacal liquor then, the accent pH value is 7.5-8;
Two, be warming up to 38-42 ℃, add that trimeric cyanamide is follow-up continuously to be warming up to 65-75 ℃, test reaction liquid is water-soluble after 40-60 minute, when water-soluble when reaching 100% reaction finish;
Three, add methyl alcohol and stir discharging behind the naturally cooling.
Above-mentioned technology also can add the buck that is formed by sheet alkali and water dissolution simultaneously when adding ammoniacal liquor.
Papery high pressure provided by the invention is decorated PLASTIC LAMINATED impregnated melamine resol, the expensive phenol of trimeric cyanamide alternative former about 30% carries out modification by using cheaply, about 500 yuan of resol cost minimizings per ton, thus the production cost that high pressure is decorated PLASTIC LAMINATED effectively reduced.And, effectively reduced the volatile component of resol owing to significantly reduced the consumption of phenol, and then reduced high pressure and decorated the pollution of PLASTIC LAMINATED to room air, the safety and environmental protection effect had.After tested: content of free aldehyde≤0.8%, free phenol content≤4%.In addition, that the resin that the present invention utilizes trimeric cyanamide and phenol, formaldehyde reaction to generate has is heat-resisting, wear-resisting, the characteristics of high strength and good stability, can improve the performance that resol and high pressure are decorated PLASTIC LAMINATED.In addition, production technique provided by the invention has that flow process is simple, the characteristics of easy handling.
