Description
Technical field
The present invention relates to Furniture manufacturing technical field more particularly to a kind of formaldehyde it is nearly zero release low smell Kang Chun plate and its
Preparation process.
Background technique
As people's living standard improves, also higher and higher, especially wood-based plate man is required for the environmental-protecting performance of furniture
The smell and Formaldehyde of tool.For the Form aldehyde release of wood-based plate and furniture, there are special detection method and index in current country
It is required that state compulsory standard GB18580-2017 releases the formaldehyde of wood-based plate and its product (including impregnated paper face artificial board)
High-volume requirement≤0.124mg/m3, it is identified as E1；For the smell of wood-based plate and furniture, national industry is carried out without relevant criterion
Regulation and limitation.
The current common thick china of Wood-based Panel Furniture, predominantly Surface decorated woodbased panels with paper impregnated thermosetting resins on the market, are passed through by substrate
Impregnated bond paper facing forms.The substrate of substrate, predominantly urea-formaldehyde glue production, burst size of methanal execution state compulsory standard≤
0.124mg/m3；Impregnated bond paper, predominantly melamine-impregnated bond paper, burst size of methanal A grades≤1.5mg/L, B grades≤
3.0mg/L。
With impregnated bond paper facing made of common melamine-impregnated bond paper paste substrate is artificial on the market at present
Plate even if burst size of methanal meets state compulsory standard requirement, but still has the following problems: 1, such impregnated paper face artificial
Plate still has biggish burst size of methanal, and it is a large amount of in room in use, it is possible to generating room air matter to make furniture
It measures exceeded；2, such Surface decorated woodbased panels with paper impregnated thermosetting resins smell is larger.Therefore, existing artificial board formaldehyde burst size is excessively high and gas
Taste is larger to become those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
The present invention provides the low smell Kang Chun plates and its preparation process of a kind of nearly zero release of formaldehyde, solve existing people
Make the technical problem that plate burst size of methanal is excessively high and smell is larger.
The present invention provides a kind of preparation processes of the low smell Kang Chun plate of nearly zero release of formaldehyde, comprising the following steps:
Step 1: smell is carried out to substrate and burst size of methanal detects, the smell and burst size of methanal of the detection substrate,
The substrate is the formaldehydeless addition substrate of MDI glue production；
Step 2: removing the gas of substrate internal residual by vacuumizing mode before overlaying；
Step 3: smell being carried out to impregnated paper and burst size of methanal detects；
Step 4: the substrate and impregnated paper that step 2 is obtained form Kang Chun plate by hot pressing.
Preferably, the impregnated paper is melamine impregnated paper.
Preferably, the melamine impregnated paper is the melamine impregnated paper of the chitin eliminating smell agent added with 10%.
Preferably, the ingredient of the eliminating smell agent includes nanometer silicon wafer.
Preferably, smell≤2.5 grade of the substrate, formaldehyde≤0.01mg/m3。
Preferably, smell≤1 grade of the impregnated paper, formaldehyde≤0.5mg/L.
It should be noted that by using the chitin and nanometer silicon wafer eliminating smell agent as main component for being added with 10%
Melamine impregnated paper can further achieve the purpose that reduce smell.A kind of low smell Kang Chun plate of nearly zero release of formaldehyde,
It is characterized in that, the preparation process system of the low smell Kang Chun plate of nearly zero release of the formaldehyde as described in claim 1~6 any one
?.
The present invention provides the low smell Kang Chun plates and its preparation process of a kind of nearly zero release of formaldehyde, and wherein substrate is selected
The formaldehydeless addition substrate of MDI glue production produces and uses neutral stains, release agent without containing bark, substrate in substrate material
Use is not recycled, is avoided conventional method from rotting since bark is mouldy, is repeatedly recycled and gone bad using acid stain, release agent, makes
Substrate smell turn sour, the present invention is also all detached by the odorous gas of the internal residual to substrate, thus reach into
The purpose of one step purification smell.Formaldehyde and odor detection, formaldehyde≤0.01mg/ are carried out to Kang Chun plate made from the embodiment of the present invention
m3, oder levels≤2.5 grade.
Specific embodiment
The embodiment of the invention provides the low smell Kang Chun plates and its preparation process of a kind of nearly zero release of formaldehyde, solve existing
Somebody makes the technical problem that plate burst size of methanal is excessively high and smell is larger.
In order to make the invention's purpose, features and advantages of the invention more obvious and easy to understand, below in conjunction with the present invention
Embodiment, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that the embodiments described below
Only a part of the embodiment of the present invention, and not all embodiment.Based on the embodiments of the present invention, ordinary skill
Personnel's all other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Embodiment 1
1), the formaldehydeless addition substrate for selecting MDI glue to produce from substrate supplier；
2), melamine impregnated paper is selected from impregnated paper supplier；
3), the smell of substrate is detected using the odor detection method that enterprise formulates, is examined according to national standard method
Survey the burst size of methanal of substrate；
4) smell for the odor detection method detection impregnated paper formulated with enterprise, with the detection method of national Specification,
Detect the burst size of methanal of impregnated paper；
5) by the substrate after above-mentioned detection aeration-drying 15 days or more in warehouse；
6) after substrate aeration-drying, the gas of substrate internal residual is removed by vacuumizing mode before overlaying；
7) it will be overlayed to form Kang Chun plate with hot press by step 6) treated substrate and impregnated paper；
8) above-mentioned Kang Chun plate is placed on cooling plate rack and is cooled down；
9) by step 8) treated Kang Chun plate aeration-drying 15 days or more in warehouse；
10) the Kang Chun plate later to step 9) processing detects, formaldehyde≤0.01mg/m3, oder levels≤2.5 grade are i.e.
For qualified products.
The performance test results of Kang Chun plate in 1 Examples 1 to 3 of table and comparative example
Note: 040, different batches, different colours texture are represented 818,162 for different colours and the decorative paper of texture, 1.2.3
Ordor removing letterweight patch product.
From the foregoing, it will be observed that in current country, the temporary odorlessness standard of industry, 3 grades of substrate smell > on the market；National compulsory
