[ description of the drawings ]
FIG. 1 is a production flow diagram of the present invention.
[ detailed description of the invention ]
The invention provides a brand new environment-friendly production process of a deformation-preventing resin sheet for wooden doors (paint-free doors), which comprises the following steps:
step 1) covering a resin adhesive film with hot melting property on the back surface of a decorative surface material on the surface of a wooden door by heating with a film covering machine, wherein the heating temperature is 60-120 ℃;
step 2) flatly pasting the decorative surface material and the large board which are covered with the resin adhesive film through a large board flat pasting coating machine or a PUR hot melt adhesive flat pasting machine to form an upper large board and a lower large board of the decorative surface wood door;
step 3) producing a large plate with a shape and a concave-convex surface, and performing mould pressing, plastic sucking, coating, flat pasting on the decorative surface of the large plate by using a negative pressure plastic sucking machine or a positive and negative pressure plastic sucking machine;
step 4) pre-pasting films on two symmetrical surfaces of the frame battens or the plate battens in the middle of the wooden door, and binding the frame battens or the plate battens with the pre-pasted films by workers to form a frame for standby;
step 5) conveying the stacked wooden doors into an industrial microwave press through an automatic production line, and performing microwave operation on the wooden doors under the premise of pressure to thermally activate, bond and fix the plates with the decorative surfaces on the upper and lower sides of the wooden doors and the frame;
and 6) finally, cutting edges and sealing edges of the wooden door, and thus finishing the finished wooden door.
The invention is further described below with reference to the following figures and specific examples:
production and manufacture of wood door decorative fabric and decorative panel:
firstly, various decorative plane materials (such as PET, PVC, PETR, wood veneer and the like) on the surface of the wood door are coated on the back surface of the decorative material by a coating machine through heating (the temperature range is 60-120 ℃) resin adhesive films (such as single-component and double-component hot-melt adhesive films which are mixed or chemically synthesized by VAE, PU, TPU, PUR and the like) with hot-melt characteristics.
The decorative surface material with the hot-coated adhesive film can be flatly pasted and coated on a large plate by a large plate flatly pasting coating machine, or the decorative surface material and the large plate can be flatly pasted by a PUR hot melt adhesive flatly pasting machine; secondly, the material with the modeling concave-convex modeling surface can be subjected to mould pressing, plastic sucking, coating and flat pasting of the large board decoration surface through a negative pressure plastic sucking machine or special equipment of the positive and negative pressure plastic sucking machine.
Secondly, a frame (commonly called a framework) batten or a multilayer plate batten in the middle of the wooden door passes through two vertical face heating and pasting equipment; the two symmetrical surfaces of the wood frame strip are pre-pasted with the films, and the wood strip or the plate strip which is pre-pasted with the films is bound with the frame (commonly called as a framework) by workers for standby.
Thirdly, when the wooden door is produced by automatic assembly line operation, the decorative surface of the plate stuck with the decorative surface is placed downwards (such as the step 1 or the step 2 of the method), the wooden door frame with the hot melt resin film is bound, the plate stuck with the decorative surface is placed, and the decorative surface is placed upwards; the stacking is repeated, and the multiple wooden doors can be simultaneously subjected to microwave hot-pressing bonding production; or putting a plate with a decorative surface (such as the step 1 or the step 2), putting a layer of resin film, putting a wooden door frame, putting a layer of resin film and finally putting the plate with the decorative surface.
And fourthly, conveying the stacked wooden doors (such as the third wooden door) into an industrial microwave press through an automatic production line, performing microwave operation for about 30-300 seconds on the premise of pressure (the range value is 0.2-30mpa), performing thermal activation bonding and fixing on the plates with the decorative surfaces on the upper and lower sides of the wooden doors and a frame (commonly called a framework), and then entering the next procedure, and performing edge cutting and sealing one-time production operation on the wooden doors to finish the finished wooden doors.
The wood door panel and the wood door frame are combined and hot-pressed to be bonded through the flat wooden door panel and the microwave press, so that the old market process production process can be well avoided, a large amount of moisture brought to the wooden door panel and the wooden door frame by repeatedly distributing glue, and the production process is equivalent to secondary dewatering and drying operation of the wooden door. The most key core advantage is that three wastes formed by repeated glue distribution of liquid glue which is not environment-friendly are eliminated in the whole production process, and a great amount of manual operation and staff body injury caused by an laggard process are eliminated, so that a great amount of work sites are saved, the production benefit is improved, and perfect environment-friendly online production is realized.
The key of the deformation of the wooden door is that the old process coats liquid glue on the upper panel cloth and the lower panel cloth of the wooden door and coats liquid glue on the frame cloth of the wooden door in the production process to bring a large amount of water, so that the overall water content of the wooden door is high, and the stress of the whole board is caused by irregular change. The deformation rate of the wooden door produced by the method can be greatly reduced to be close to zero, and the problem that the wooden door is easy to deform in production is well solved.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
