Abstract
The invention discloses preparation raw materials of an aldehyde-free environmentally-friendly adhesive for artificial boards. The preparation raw materials include the following materials in parts by mass: 750-1200 parts of sodium silicate, 2-5 parts of oxalic acid, 2-5 parts of 98% concentrated sulfuric acid, 200-400 parts of water, 20-30 parts of borax, 20-40 parts of urea, 100-150 parts of starch, and 50-80 parts of sodium hydroxide. According to the preparation raw materials and method of aldehyde-free environmentally-friendly adhesive for the artificial boards, the prepared adhesive does not contain formaldehyde, polychorinated biphenyls and other toxic and harmful substances, is strong in adhesive force, clean and environmentally-friendly, simple in production, convenient to use, and low in cost, and has high economic benefits and social benefits, thus being wide in development and application prospects, and beneficial to popularization.
Description
Technical field
The present invention relates to a kind of wood-based plate tamanori, relate in particular to raw materials and the method for a kind of wood-based plate without aldehyde environmental protection tamanori.
Background technology
Tamanori, claims again " sizing agent ", is commonly called as " glue ", has the material of good bonding ability.Divide inorganic substance and organic substance two classes.Inorganic substance have water glass etc.; Organic substance is all macromolecular compound, has from various vegeto-animal natural high moleculer eompounds and many synthetic gums, as dextrin, rubber, epoxy resin, resol etc.Can bind the materials such as metal, glass, timber, it is widely used in the departments such as industry, traffic, building and daily life.Tamanori has the very wide application of sending out in fields such as decorative building materials, in January, 2002, country promulgated GB18580-2001 " burst size of methanal in house decorative material, wood-based plate and goods thereof ", as pressure standard, and carry out in July, 2003, but up to the present, the wood-based plate of selling on market still major part belongs to substandard product, and the content of its free formaldehyde still exceeds standard far away.Although part producing producer has been used UF Resin Adhesive with Low Toxicity, free formaldehyde discharges and exists all the time to indoor environmental pollution and to the harm of HUMAN HEALTH.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, raw materials and the method for a kind of wood-based plate without aldehyde environmental protection tamanori are provided, the tamanori making is not containing hazardous and noxious substances such as formaldehyde, multichannel biphenyl, and adhesive power is strong, clean environment firendly.
Technical scheme: a kind of wood-based plate of the present invention is without the raw materials of aldehyde environmental protection tamanori, formed by following mass parts material: water glass 750-1200 part, oxalic acid 2-5 part, 98% vitriol oil 2-5 part, water 200-400 part, borax 20-30 part, urea 20-40 part, starch 100-150 part, sodium hydroxide 50-80 part.

As preferably: above-mentioned wood-based plate, without the raw materials of aldehyde environmental protection tamanori, comprises following mass parts material: 1000 parts of water glass, 3 parts of oxalic acid, 98% 3 parts of the vitriol oils, 300 parts, water, 3 parts of boraxs, 30 parts, urea, 125 parts of starch, 65 parts, sodium hydroxide.
Adopt above-mentioned raw materials to prepare the method for wood-based plate without aldehyde environmental protection tamanori, comprise the steps:
(1) oxalic acid is heated in water glass and stir 30 minutes;
(2) after 98% vitriol oil is added to the water stirs, then add borax, continue to be stirred to entirely molten;
(3) solution step (2) being obtained is poured in the solution of step (1) gained, continues to stir 30 minutes;
(4) urea is poured in the solution of step (3) gained, continued to stir 30 minutes;
(5) solution of step (4) gained is slowly warming up to 40 degrees Celsius, adds starch, and continue to be slowly warming up to 70 degrees Celsius, close thermal source, continue to stir;
(6) while the solution of step (5) gained being cooled to 40 degrees Celsius, add sodium hydroxide, continue to be stirred to temperature to normal temperature.
The tackiness agent making can be used for the manufacture of artificial timber board.
The present invention compared with prior art, its beneficial effect is: a kind of wood-based plate of the present invention is without raw materials and the method for aldehyde environmental protection tamanori, the tamanori making is not containing hazardous and noxious substances such as formaldehyde, multichannel biphenyl, and adhesive power is strong, clean environment firendly, produce simple, easy to use, with low cost, there is very high economic benefit and social benefit, exploitation utilization prospect is boundless, is beneficial to popularization.
