Description
[technical field]
The present invention relates to a kind of manufacture method and products thereof, particularly a kind of manufacture method and products thereof of low VOC product.
[background technology]
Along with people's living standard improves, automobile enters the quickening of family's paces, and automotive interior air pollution problems inherent has become the focus of consumer's general concern.At present, the professional institutions such as the Automobile Associations of various countries have all formulated relevant criterion and have required to limit the air quality in vehicle, and world-famous Automobile Enterprises formulates respective company standard respectively with management and control in-car air quality.
VOC is that VOC (VolatileOrganicCompounds) is called for short, and is the major reason affecting in-car air quality.VOC mainly comprises the materials such as alkane, alkene, aromatic hydrocarbons, aldehydes or ketone, there is special penetrating odor, and part is listed in carcinogenic substance, as vinyl chloride, benzene, polycyclic aromatic hydrocarbon etc., part VOC also has destruction to ozone layer, as CFC and HCFC.During VOC excessive concentration, be easy to cause acute poisoning, the lighter there will be headache, dizziness, cough, Nausea and vomiting; There will be tic time serious, and the liver of people, kidney, brain and nervous system can be hurt.Prove through foreign medical science research, live in the pregnant woman in VOC ambient influnence, cause the probability of fetal anomaly far away higher than ordinary person, and likely child's intelligence development is from now on impacted.
See the vehicle articles procedure for producing more complicated of the button classes such as letter character at present on the market.If do not need transparent product, after general employing injection moulding, material sprays paint, and is carved by symbol radium after spraying paint again; Or material sprays paint after injection moulding, after republish letter character.Processing procedure is long, produces yield not high, and in the processing procedure that sprays paint contained solvent etc. its can produce VOC, pollute the environment, the reliability of product neither be fine, easily falls paint after using a period of time.
In view of this, the manufacture method developing a kind of low VOC product is necessary, to solve the problem in fact.
[summary of the invention]
Therefore, the object of the present invention is to provide manufacture method of a kind of low VOC product and products thereof, the method can manufacture needs letter character class button product, and processing procedure is short, yield is high, the reliability of product is good.
In order to achieve the above object, the manufacture method of low VOC product of the present invention, for the manufacture of letter character class button product, the method comprises the following steps:
(1) adopt first to penetrate material to carry out first and penetrate injection mo(u)lding, form first and penetrate product, described first penetrates on product and has letter character class shape, and wherein, described first penetrates material adopts low VOC material;
(2) adopt second to penetrate material to penetrate first and product carries out second penetrate injection mo(u)lding, form second and penetrate product, described second penetrates and product exposes described first and penetrate letter character class shape on product, and wherein, described second penetrates material is adopted as low VOC material.
Alternatively, twice injection molding in described step (1), (2) is dijection shaping (DoubleInjection) or the mode imbedding ejection formation (Insertmolding).
Alternatively, described first material is penetrated for carrying out the low VOC material that smell (Odor) VDA270 test value is less than or equal to 3.
Alternatively, described second material is penetrated for carrying out the low VOC material that smell (Odor) VDA270 test value is less than or equal to 3.
Alternatively, first in described step (1) is penetrated material and is adopted PC.
Alternatively, second in described step (2) is penetrated material and is adopted ABS.
Alternatively, the model that described ABS selects bright and beautiful lake day beautiful is the ABS of HU600EM.
Alternatively, twice injection mo(u)lding processing procedure in described step (1), (2) adopts RHCM (RapidHeatCycleMolding) rapid heat cycle forming technique.
The present invention also provides a kind of product, and this product is the product produced after above-mentioned manufacture method manufactures.
Alternatively, described product is the letter character class button product used in automobile.
Compared to prior art, manufacture method of low VOC product of the present invention and products thereof, be not adopt spray paint after radium carving or printing form letter character class shape, but penetrate material by first and form described shape and expose described letter character class shape when second penetrates product.Therefore tool has the following advantages: technique is more simple efficient, and processing procedure is short, yield is high; Need not spray paint, and select low VOC material, processing procedure environmental protection, Product Green environmental protection; Product is produced by twice ejection formation, and without the need to spraying paint, avoid paint, reliability is high.

Fig. 2 illustrates the product embodiments schematic diagram that the manufacture method for low VOC product of the present invention is produced.
[detailed description of the invention]
For having further understanding to object of the present invention, method step and effect, be now described with reference to the accompanying drawings as follows.
Refer to Fig. 1, Fig. 1 illustrates the flow chart of the manufacture method into low VOC product of the present invention.
In order to achieve the above object, the manufacture method of low VOC product of the present invention, for the manufacture of letter character class button product, the method comprises the following steps:
Step 101: adopt first to penetrate material and carry out first and penetrate injection mo(u)lding, forms first and penetrates product, and described first penetrates on product and have letter character class shape, and wherein, described first penetrates material adopts low VOC material;
Step 102: adopt second to penetrate material and penetrate first and product carries out second penetrate injection mo(u)lding, form second and penetrate product, described second penetrates and product exposes described first and penetrate letter character class shape on product, and wherein, described second penetrates material is adopted as low VOC material.
