Abstract
In the present paint-free ecological plate production process, use plywood and joinery board core as the substrate, use a large amount of urea-formaldehyde glue with glues such as poplar veneer, science and technology veneer, melamine impregnated paper and paste together, all use a certain amount of formaldehyde in the production process of science and technology veneer, melamine paper in addition, after the stack of various factors, cause the exceeding standard of formaldehyde emission very easily, cause certain harmful effects to consumer health. The invention discovers that a certain proportion of German Ryansun is added in the process of preparing urea-formaldehyde glue®Biological formaldehyde purification factor can effectively control the formaldehyde emission of the board, and the board has the formaldehyde purification function, can adsorb free formaldehyde in the air, and ensures that the formaldehyde content of the indoor air reaches the standard.
Description
Technical Field
The invention relates to the technical field of decoration and building materials, in particular to a production process of a paint-free ecological plate capable of purifying formaldehyde.
Background
The paint-free ecological board (also called paint-free board or ecological board) has the characteristics of rich design and color, beautiful surface, convenient construction, scratch resistance, wear resistance and the like, and simultaneously, the base material is multilayer solid wood (plywood) and laminated wood board (such as malachite, fir, tung, poplar and the like), is very close to the solid wood, but the price is far lower than the solid wood, so the paint-free ecological board becomes the first choice building material for consumers, and is widely applied to the manufacture of various furniture such as wardrobes, bathroom cabinets, television cabinets, shoe cabinets and the like in home decoration.
In the present paint-free ecological plate production process, use plywood and joinery board core as the substrate, use a large amount of urea-formaldehyde glue with glues such as poplar veneer, science and technology veneer, melamine impregnated paper and paste together, all use a certain amount of formaldehyde in the production process of science and technology veneer, melamine paper in addition, after the stack of various factors, cause the exceeding standard of formaldehyde emission very easily, cause certain harmful effects to consumer health.
Disclosure of Invention
In order to solve the problem that the formaldehyde release amount of the paint-free ecological plate exceeds the standard, the invention provides the production process of the paint-free ecological plate capable of purifying formaldehyde, which has the formaldehyde purification function, can adsorb the formaldehyde released from the paint-free ecological plate, ensures that the formaldehyde release amount of the ecological plate is far lower than the national standard, and can adsorb free formaldehyde in air to play a role in purifying air.
The invention provides the following technical scheme:
1) the core plate is subjected to putty scraping and sanding treatment.
2) Glue mixing: mixing German ryan Ryansunun®Mixing biological formaldehyde-purifying factor, flour and urea-formaldehyde glue according to the proportion of 0.1:1:2.5, and stirring uniformly.
3) Gluing and coating a veneer: and uniformly coating the prepared glue on two surfaces of the core plate, covering the core plate with a single plate, and standing for half an hour to one hour.
4) Cold pressing and hot pressing: and (5) putting the mixture into a cold press for half an hour, and then putting the mixture into the hot press.
5) Gluing and coating a technical wood veneer: and uniformly coating the mixed glue on the surface of the veneer, covering with scientific wood veneer, and standing for half an hour to one hour.
6) Cold pressing and hot pressing: and (5) putting the mixture into a cold press for half an hour, and then putting the mixture into the hot press.
7) Pasting paper: and gluing the melamine impregnated paper with the substrate by using a hot press.
The invention discovers that a certain proportion of German Ryansun is added in the process of preparing urea-formaldehyde glue®Biological formaldehyde purification factor can effectively control the formaldehyde emission of the board, and the board has the formaldehyde purification function, can adsorb free formaldehyde in the air, and ensures that the formaldehyde content of the indoor air reaches the standard.
Detailed Description
1) The core plate is subjected to putty scraping and sanding treatment.
The core board is made of multi-layer solid wood or core-board (such as Maliuta asiatica, fir, tung, poplar, etc.).
2) Glue mixing: mixing German ryan Ryansunun®Mixing biological formaldehyde-purifying factor, flour and urea-formaldehyde glue according to the proportion of 0.1:1:2.5, and stirring uniformly. The urea-formaldehyde glue needs to be detected before use, and reaches E1 grade. The prepared glue needs to be used up within 5 hours.
3) Gluing and coating a veneer: uniformly coating the prepared glue on two surfaces of a core plate, covering a single plate, and standing for half an hour to one hour; the glue coating amount is controlled to be 1.1-1.2 KG/sheet; after the veneer is covered, if the standing time is too long, the surrounding is sprayed with mist water.
4) Cold pressing and hot pressing: and (5) putting the mixture into a cold press for half an hour, and then putting the mixture into the hot press. The cold pressing pressure is 9MPa, the hot pressing pressure is 7.5MPa, the temperature is 125 ℃, and the time is 20 minutes.
5) Gluing and coating a technical wood veneer: and (3) uniformly coating the glue on two sides of the substrate, covering with technical wood veneers, and standing for half an hour to one hour. The scientific wood veneer needs to be detected before use to reach E1 level. The coating amount is controlled to be 0.8-0.9 KG/sheet.
6) Cold pressing and hot pressing: cold pressing for half an hour in a cold press, and putting into a hot press. The cold pressing pressure is 7MPa, the hot pressing pressure is 8MPa, the temperature is 125 ℃, and the time is 6 minutes.
7) Pasting paper: the melamine paper was applied to both sides of the board using a hot press. The hot pressing pressure is 9MPa, the temperature is 125 ℃, and the time is 7 minutes.
