Technical Field

The invention relates to the technical field of plate processing, in particular to a manufacturing process of a pine europaea board.

Background

Oriented Strand board (osb) has developed into an important product group in the market of building materials and decorative materials in our country, and has gradually become a mainstream board in the decoration industry, and more a landmark material for medium-high grade decoration. The European pine board is prepared from fast-growing forests and intermediate forests with environmental protection significance, eucalyptus, fir, poplar and the like are usually used as raw materials, and the pine has the characteristic of high grease, so that the problems of difficult bonding and difficult preforming exist in the process of preparing the European pine board from the European pine board, the mechanical property of a finished product is poor, and the use standard cannot be met.

Disclosure of Invention

Therefore, based on the above background, the present invention provides a process for manufacturing pine europaea boards, which overcomes the problem of heavy oil in pine.

The invention is realized by the following technical scheme:

a manufacturing process of a pine euryale ferox plate comprises the following steps:

s1: processing pine into pine slices with the thickness within 1 mm;

s2: drying pine wood slices until the moisture content is 5-20%, and conveying the pine wood slices to a storage bin for later use;

s3: carrying out glue mixing treatment on the pine wood slices;

s4: paving the pine thin slices mixed with the glue and performing prepressing molding;

s5: and carrying out hot press molding on the preliminarily molded pine sheet to obtain the pine European pine plate.

Further, it also includes step S6: and cutting the forming plate to form the specification plate.

Further, the pine used in step S1 is masson pine.

Further, the adhesive for glue mixing in step S3 is a modified urea-formaldehyde resin containing amino groups.

Further, the hot pressing temperature of the step S5 is controlled to be 120-200 ℃.

Further, the hot pressing time of the step S5 is 3-6 minutes, and the pressure is controlled to be 15-20 MPa.

By adopting the technical scheme, the method has the following beneficial effects:

compared with the existing preparation process of the euryale ferox, the preparation process of the invention not only omits the step of degreasing the pine, but also can remove the grease on the surface of the pine veneer, increase the adhesive force between the pine veneer and the adhesive and improve the mechanical property of the product, because the pine oil on the surface of the pine veneer can be subjected to a cross-linking reaction with the amino in the adhesive in the hot-press molding process; and the pine oil in the residual pine sheet can play a certain waterproof role through the oil, so that the European pine of the pine has stronger waterproof property.

Example 2: a manufacturing process of a masson pine plate comprises the following steps:

s1: processing the masson pine into pine slices with the thickness within 1mm and different width and length by a flaker;

s2: drying the pine wood slices until the moisture content is about 15%, and then conveying the pine wood slices to a storage bin for later use;

s3: carrying out glue mixing treatment on the pine wood slices;

s4: paving the pine thin slices after glue mixing in a paving machine, and performing prepressing molding through a prepress;

s5: conveying the preliminarily formed pine slices into a hot press, and hot-pressing for 3-6 minutes at the temperature of 150-.

S6: and conveying the formed plate to an edge cutting machine for cutting and forming after cooling to manufacture the specification plate.

And step S3, the adhesive for glue mixing is modified urea-formaldehyde resin containing amino groups.

The photo of the pinus massoniana prepared by the invention shown in figure 1 shows that the prepared pinus massoniana has clear surface texture, golden yellow color and strong natural feeling and aesthetic property. The quality of the europaea prepared by the invention is detected (detection is carried out by the institute of quality supervision and inspection of products, Anhui province), and the detection results are shown in the following table:

detecting items	Unit of	Standard specification value	Test results	The result of the judgment
					Static bending strength	MPa	10.0	13.8	Qualified
Internal bond strength	MPa	0.24	0.70	Qualified
					Formaldehyde emission	mg/m3	≤0.124	0.078	Qualified

The above table shows that the masson pine plate prepared by the invention not only can solve the problem of much grease of masson pine, but also can improve the mechanical strength of the masson pine plate through the reaction of the grease and an adhesive, so that the masson pine plate meets the use standard, and the grease in the pine sheet can also enhance the waterproofness of the product.

In the actual production process, the moisture of the dried pine wood slices in the step S2 is preferably controlled to be 5-20% according to the production condition, the final finished product is easy to bubble due to the fact that the moisture content is too high, and the final mechanical property of the product is influenced due to poor bonding between the pine wood slices and the adhesive; and the water content is too small, not only can cause drying safety, deposit and have the potential safety hazard to still can take place the grease fission, this can increase later stage and glue and consume, the cost increase.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
