Description
Technical field
The present invention relates to decorative board material technical fields, more particularly to a kind of aqueous no aldehyde decoration panel and its production technology.
Background technique
As the improvement of people's living standards, people are higher and higher to indoor finishing requirements.Existing decoration panel
More meeting generation environment contamination phenomenons, endanger to the health care belt of modern people in production, for example existing decoration panel produces work
Three-aldehyde glue is mostly used in skill, easily releases free formaldehyde, and formaldehyde phenomenon is serious, directly affects people's health.And face
The quality of production of plate is influenced by its production technology, is adhesive quality first, and adhesive requires performance to stablize, there is enough gluings
Intensity, resin content and viscosity are suitable for having the sufficiently long active phase just to can guarantee that normal operating and product indices conform to
It asks, is critical secondly, controlling Veneer moisture with flatness, since aqueous adhesive is using water as medium, plate is contained
Water rate requires to be apparently higher than three-aldehyde glue, in postorder hot pressing moisture evaporation, it is necessary to assure finished product plate moisture content is in qualified model
In enclosing, in addition, having needed to be grasped two links of resin added and storage, glue amount is excessive, blocked up or very few, can in gluing procedures
Influence board quality and production cost；Resting period need to also make reasonable change with climate change.For the hair for complying with modern industry
Exhibition, it is desirable that inexpensive, efficient production method, this requires need in the production technology of decoration panel constantly by changing
Into shortening production time and reduction production cost.
For this purpose, it is proposed that a kind of aqueous no aldehyde decoration panel and its production technology solve the above problems.
Summary of the invention
The purpose of the present invention is to solve the problems of the prior art, and the aqueous no aldehyde decoration panel of one kind that proposes and
Its production technology.
To achieve the goals above, present invention employs following technical solutions:
A kind of aqueous no aldehyde decoration panel, including two pieces of core plates, one piece of panel and one piece of backboard, the one of every piece of core plate
Face is equipped with wavy surface, and is fitted closely between the wavy surface of two pieces of core plates by the first rubberised layer, the panel and the back
Plate passes through the second rubberised layer respectively and fits closely on two pieces of core plates；
First placing groove there are two symmetrically being opened up on the panel upper surface, and pressure is placed in each first placing groove
Plate, symmetrically opens up that there are two the second placing grooves on the lower surface of the backboard, and is placed with follow block in each second placing groove,
Each pressing plate is slidably connected in the corresponding follow block in position, is mounted on hexagon socket head cap screw on each follow block,
And hexagon socket head cap screw is threadedly coupled with pressing plate.
In above-mentioned aqueous no aldehyde decoration panel, the pressing plate is divided into holding section, interconnecting piece and moving portion, and interconnecting piece
It is connected between holding section and moving portion, the holding section is fastened in the first placing groove, and the height of holding section is put with first
The height for setting slot inner wall is equal, i.e. the upper surface of panel and the upper surface of holding section is generally aligned in the same plane, the hexagon socket head cap screw
It is threaded in moving portion.
In above-mentioned aqueous no aldehyde decoration panel, the follow block includes horizontal part, vertical portion and mounting portion, and vertical portion
It is connected between horizontal part and mounting portion, the height of the mounting portion is equal with the height of the second placing groove inner wall, i.e. backboard
