Chamfering latch floor production method
Technical field
The present invention relates to floor production field, especially prepare chamfering not by the chamfering latch floor production method of floor wearing layer thickness limits.
Background technology
In recent years, snap close PVC plastic vinyl tile is used widely, and its laying is convenient, waterproof and dampproof, be easy to arrange, long service life, is particularly suitable for being laid on the large public arena of visitors flowrate as market or business offices.
But, this kind of latch floor is in the market when producing, and mostly product chamfering is to carry out when mortice opening simultaneously, needs to utilize chamfering tool to carry out chamfering, and chamfered can only be carried out to wearing layer on the floor of more than 0.5mm, chamfering width and angle are all subject to the restriction of wearing layer thickness; For the lower wearing layer of thickness when chamfering, easily base material is exposed, thus make floor edge not wear-resisting, make base material can not be effectively protected, greatly compromise the application life on floor.
Summary of the invention
In order to solve above-mentioned existing issue, the invention provides a kind of chamfering latch floor production method not needing chamfering tool, be not subject to wearing layer thickness limitation.
Realize above-mentioned purpose, the technical solution used in the present invention is chamfering latch floor production method, it is characterized in that, comprises the following steps:
A, by composition floor each layer carry out laying successively;
Chamfering is carried out in b, the floor that employing chamfering formwork is good to step a laying under hot pressing state;
C, employing rubber roll carry out UV coating, solidification to the floor surface that step b obtains;
D, floor fluting, tenon processed that step c is obtained, obtained finished product.
In one embodiment of the invention, described hot pressing temperature is 125-140 DEG C, and hot pressing time is 1500 seconds to 2300 seconds.
In one embodiment of the invention, the edge of described chamfering formwork is with circular arc chamfering.
In one embodiment of the invention, described chamfering formwork is shallow basin body, between first inwall and the second inwall of described shallow basin body inner surface of the inner surface of described shallow basin body, be provided with circular arc chamfering.
Further, the radius of corner of described circular arc chamfering is 0-1.2mm.
Further, the top edge of described shallow basin body is connected with tub wall, and described tub wall is fixedly connected with described shallow basin body, described tub wall is provided with several steam vents, and described steam vent is connected with the pelvic cavity of described shallow basin body.Described tub wall is outstanding outside shallow basin body.
Further, the hardness of described rubber roll is 16 °-25 °.
The present invention has following beneficial effect: can make chamfering width and angle not by the limitation of floor wearing layer thickness by circular arc chamfering template, by the design of shallow basin body circular arc chamfering, in the energy-conservation enough rounding process realized accurately latch floor wearing layer of hot pressing complex loop, do not need the chamfering tool that cost of manufacture is high, can realize latch floor chamfer angle more greatly, wider; Meanwhile, the tub wall extended arranges steam vent, exhausting problem when efficiently solving hot pressing in chamfering formwork, can not only obtain good hot pressing composite effect, also can not destroy the circular arc chamfering effect on floor; In addition, adopt the rubber roll of above-mentioned hardness to carry out film coating UV coating, ensureing rubber roll application life and film is uniform while, all fully can also contact the whole cambered surface of rounding, make floor surface film complete, improve product quality.

Detailed description of the invention
Embodiment 1
By wearing layer 1, the color rete 2 of composition chamfering latch floor of the present invention, laying is good successively for substrate layer 3, and chamfering is carried out on good floor to adopt the radius of corner of circular arc chamfering 4 to be chamfering formwork 5 pairs of layings of 0.4mm; Described chamfering formwork is shallow basin body, between first inwall and the second inwall of described shallow basin body inner surface of the inner surface of described shallow basin body, be provided with radius is 0.4mm circular arc chamfering, described first inwall 11 is the sidewall of shallow basin body, and described second inwall 22 is the bottom of shallow basin body inner surface; Wherein, the temperature of hot pressing compound tense is 135 DEG C (positive and negative deviation is 5 DEG C), hot pressing time is that 1800 seconds (positive and negative deviation is 20 seconds) is when hot pressing, floor has 1mm from top to bottom and is absorbed in a formation complete totally enclosed shape in template, in order to solve the problem be vented in template, therefore on the tub wall 6 of described chamfering formwork, be symmetrically arranged with four steam vent 7(composition graphs 1, Fig. 1 is the sectional view along described steam vent axis), described steam vent 7 is connected with the pelvic cavity 8 of described shallow basin body, and the pore internal diameter of described steam vent 7 is 2mm; Then, employing hardness is that the rubber roll of HB 20 ° (positive and negative deviation is 2 °) carries out UV coating, solidification to floor surface obtained above, obtains UV film 100; Finally by cutter to the floor fluting after chamfering, tenon processed, the obtained chamfering latch floor with corresponding arc bevelling 9.
Embodiment 2
By wearing layer 1, the color rete 2 of composition chamfering latch floor of the present invention, laying is good successively for substrate layer 3, and chamfering is carried out on good floor to adopt the radius of corner of circular arc chamfering (sign) to be chamfering formwork 5 pairs of layings of 1mm; Wherein, the temperature of hot pressing compound tense is 125 DEG C (positive and negative deviation is 5 DEG C), hot pressing time is 2000 seconds (positive and negative deviation is 20 seconds), when hot pressing, floor has 1mm from top to bottom and is absorbed in a formation complete totally enclosed shape in template, in order to solve the problem be vented in template, therefore on the tub wall of described chamfering formwork, be symmetrically arranged with four steam vents 7, pore 7 internal diameter of described steam vent is 2mm; Then, employing hardness is that the rubber roll of HB 20 ° (positive and negative deviation is 2 °) carries out UV coating, solidification to floor surface obtained above, obtains UV film 100; Finally by cutter to the floor fluting after chamfering, tenon processed, obtained finished product.
Above-mentioned specific embodiment is only used to explain bright the present invention; but not be limit the invention; in the protection domain of aim of the present invention and claim, to any replacement and change of not paying creative work that the present invention makes, all protection scope of the present invention will be fallen into.
