Abstract
The invention discloses environment-friendly melamine glue belonging to the technical field of floor woodgrained paper and furniture paper, and a preparation method of the melamine glue. The melamine glue comprises the following components in parts by weight: 25-32 parts of formaldehyde, 12-17 parts of melamine, 0.1-1.0 part of diethylene glycol, 1-3 parts of pycreus globosus extract, 1-2 parts of digitaria sanguinalis extract and 15-20 parts of water. According to the melamine glue, the pycreus globosus extract is added, so that non incompletely-reacted melamine can be effectively absorbed; the digitaria sanguinalis extract is added, so that harmful gas-formaldehyde can be effectively absorbed. Therefore, the melamine glue is relatively environment-friendly.
Description
Technical field
The invention belongs to floor woodgrained paper, furniture paper technical field, trimeric cyanamide glue being specifically related to a kind of environmental protection and preparation method thereof.
Background technology
Floor woodgrained paper, furniture paper generally adopts wood pulp kraft paper, and intensity is comparatively large, and the decorative pattern on woodgrained paper is what print, and woodgrained paper thickness is generally at 0.5-1.0mm.Woodgrained paper in use, needs to flood, to reach woodgrained paper smooth surface, texture, and antiacid alkali, the performances such as resistance to compression, resists cold, fire-resistant.
Trimeric cyanamide is commonly called as melamine, extract of protein, IUPAC called after " 1,3; 5-triazine-2; 4,6-triamine ", is a kind of triazines nitrogen heterocyclic ring organic compound, it is white monoclinic crystal, almost tasteless, be slightly soluble in water (3.1g/L normal temperature), dissolve in methyl alcohol, formaldehyde, acetic acid, hot ethylene glycol, glycerine, pyridine etc., be insoluble to acetone, ethers, health is harmful to, be not useable for food-processing or food additives.
Trimeric cyanamide and formaldehyde reaction generate terpolycyantoamino-formaldehyde resin, a kind of dipping glue of excellent performance, but trimeric cyanamide and formaldehyde all harmful to human body, unreacted completely trimeric cyanamide and residues of formaldehyde can endanger user, and especially children's is healthy.
The flat nutgrass flatsedge of ball fringe, formal name used at school Pycreus globosus (All.) Reichb.Belong to Cyperaceae annual herb plant, all there is distribution all parts of the country, the aquatic crops such as main harm paddy rice, Ying Bai.The flat nutgrass flatsedge vitality of ball fringe, reproductivity are very strong, can absorb the chemical noxious materials such as trimeric cyanamide.
Lady's-grass, is a kind of common annual grassy weeds in field, has the ability of the obnoxious flavour materials such as very strong vitality and formaldehyde adsorption.
Current trimeric cyanamide glue, at more formaldehyde residual in preparation engineering and trimeric cyanamide harmful chemical, endangers the health of people, contaminate environment.
