Abstract

The invention discloses a manufacture method of a soft clad door. The manufacture method comprises the following steps: A, carrying out primary dedusting treatment on the surface of a medium density fiberboard; B, removing the static electricity on the medium density fiberboard; C, placing the medium density fiberboard into a dedusting chamber so as to carry out further dedusting treatment; D, feeding the medium density fiberboard after further dedusting into a dryer, wherein the temperature of the internal environment of the dryer is 30-50 DEG C, and the drying time is 30-50 seconds; E, coating a hot melt adhesive on the surface of the dried medium density fiberboard, and scraping the hot melt adhesive on the surface of the medium density fiberboard flatly by utilizing a scraper; F, fitting a cortical layer onto the surface of the medium density fiberboard coated by the hot melt adhesive, and gluing the cortical layer and the hot melt adhesive; and G, rolling the surface of the medium density fiberboard fitted with the cortical layer by utilizing a roll shaft, and fully fitting the cortical layer and the medium density fiberboard to manufacture the soft clad door. The method disclosed by the invention is capable of effectively overcoming a phenomenon that the cortical layer falls off, and no hardwares such as rivets are required to fix the cortical layer and the medium density fiberboard.

Description

A kind of preparation method of Soft Roll door

Technical field

The present invention relates to a kind of preparation method of Soft Roll door.

Background technology

The Soft Roll door also is soft door, and it normally utilizes soft cortex, cloth to be wrapped in the outer surface of plank, reaches the effect of whole Soft Roll.

The Soft Roll door normally is installed in some high-grade houses, and therefore, people are relatively high for the requirement of the each side such as the quality of Soft Roll door, performance.existing Soft Roll door is adding man-hour, normally the cortical layer of outside or bed of cloth are bonded in the outer surface of MDF in the mode of gummed, yet, the Soft Roll door that utilizes existing method to make, the cortical layer of its outer surface and the bond strength of MDF are lower, the Soft Roll door is after having used the long period, the surface cortical layer is easy to come off from MDF, in order to overcome these defects, normally after cortical layer is bonded in MDF, utilize the accessories such as rivet that cortical layer and MDF are fixed, although the Soft Roll door of this structure can overcome excoriative defect, but it is in process or use procedure, the part of being combined with rivet due to cortical layer is subject to the pressure on top surface of rivet, easily produce the phenomenon of tearing.

Summary of the invention

For the deficiencies in the prior art, purpose of the present invention is intended to provide a kind of preparation method of Soft Roll door, and it can avoid cortical layer to come off from MDF, and need not to utilize the accessories such as rivet fixedly cortical layer and MDF.

For achieving the above object, the present invention adopts following technical scheme:

A kind of preparation method of Soft Roll door, comprise the steps:

A, rough dusting is carried out on the surface of MDF process;

B, utilize the hairbrush destatic remove on MDF with static;

C, the MDF that will remove static are positioned in dirt pocket to do and carry out further dust removal process, are provided with the air exhauster that is positioned at MDF top in this dirt pocket, start air exhauster, make in dirt pocket and form negative pressure, siphon away the dust on MDF surface;

D, the MDF after further dedusting is sent into dryer, remove the moisture on MDF surface; The temperature of this dryer internal environment is 30-50 ℃, and drying time is 30-50 second;

E, to the MDF surface coating hot-melt adhesive after oven dry, PUR was heated to 140-180 ℃ before being coated on the MDF surface, then utilize scraper that the PUR on MDF surface is struck off;

F, the cortical layer of fitting to the MDF surface that has applied PUR, make cortical layer and PUR bonding;

G, utilize roll shaft in the MDF surface rolling of cortical layer of having fitted, cortical layer and MDF are fully fitted, make the Soft Roll door.

In step e, PUR is selected copolyamide or copolyesters or polyethylene or polyurethanes.

In step e, utilize the net roller with the mode of the roll extrusion surperficial coating hot-melt adhesive to MDF, the net roller is positioned at the lateral opening place in the sizing material pond of putting PUR, utilizes the direction that conveying device postpones with net roll axis vertical from the below of net roller MDF to carry.

Beneficial effect of the present invention is:

Than existing processing method, method of the present invention can improve the adhesion of cortical layer and MDF, can effectively overcome the phenomenon that cortical layer comes off, and need not to utilize the handware such as rivet fixedly cortical layer and MDF, saved the processing of Soft Roll door cost, simplified the processing technology of Soft Roll door.

Description of drawings

Fig. 1 is process chart of the present invention;

Fig. 2 is the schematic diagram of gluing process of the present invention;

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the present invention is described further:

Preparation method referring to Fig. 1 Soft Roll door of the present invention, comprise the steps:

A, preliminary dust removal process is carried out on the surface of MDF, in processing procedure, utilize the tape transport MDF, a clearer with hairbrush is set above conveyer belt, the driven by motor clearer rotates, the dust and other impurities on preliminary removal MDF;

B, utilize conveyer belt that MDF is transported to and destatics station, utilize the roller that destatics of driven by motor band hairbrush to rotate, the surface of the friction MDF of hairbrush contact, remove MDF with static;

C, the MDF that will remove static are delivered in dirt pocket, the dirt pocket top is provided with the air exhauster that is positioned at MDF top, start air exhauster, make in dirt pocket and form negative pressure, siphon away the dust on MDF surface, be printed with and may also can be siphoned away by air exhauster by the bristle on MDF in steps A, B simultaneously, thus the cleaning surfaces of assurance MDF;

D, the MDF after further dedusting is sent into dryer MDF is carried out drying and processing, remove the moisture on MDF surface, the interior environment temperature of dryer is 30-50 ℃, drying time is 30-50 second, this dryer internal environment also can be adjusted as required, as long as can reach the purpose of removing the MDF surface moisture; Through inventor's experimental verification repeatedly, the dryer interior environment temperature is 41 ℃, and when drying time was 40 seconds, drying effect was ideal, and can save as much as possible the energy.

E, surperficial coating hot-melt adhesive to the MDF that has passed through drying and processing, concrete is referring to Fig. 2, a net roller 1 that utilizes driven by motor is set on the gluing station, the side of this net roller 1 arranges one and is used for the sizing material pond 2 of putting PUR 3, this sizing material pond 2 is provided with an opening in the side near net roller 1, and in the gluing process, what continue supplies with PUR 3 to sizing

material pond

2, 2 opening parts near net roller 1 one sides show as overflow status in the sizing material pond to make PUR 3, when gluing, net roller 1 ceaselessly rotates, the PUR 3 that overflows is attached in the roll surface of net roller 1, utilize conveyer belt to carry MDF 4 along the direction vertical with net roller 1 axis, the surface of MDF 4 contacts with the bottom of net roller 1, thereby the hot-melt that net roller 1 roll surface is subsidiary is overlying on the surface of MDF 4, after gluing is completed, utilize scraper that the PUR on MDF 4 surfaces is struck off, adhesion for increasing cortical layer and MDF, and can guarantee flatness after cortical layer pastes, improve the exterior quality of Soft Roll door.In above-mentioned gluing process, also need PUR heating, its heating-up temperature is 140-180 ℃, and concrete heating-up temperature can be selected arbitrary value in above-mentioned scope for selected sizing material.In this step, PUR can be selected copolyamide, copolyesters, polyethylene, polyurethanes;

To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the claims in the present invention.
