Description de Produit

       

Vacuum plastic adhesive is a kind of water-based adhesive polyurethane glue. Waterborne polyurethane adhesives are
widely used in the market due to their water-based, non-toxic and convenient use. With the pursuit of low-carbon
environmental protection, a series of water-based adhesives have been produced.
Chinese Name: Vacuum plastic
Types : A kind of water-based adhesive polyurethane glue
Composition: Polyurethane emulsion as the main

Product description
Vacuum-absorbing plastics usually use polyurethane emulsion as the main component, which has good film-forming
properties and excellent heat resistance and water resistance after cross linking.
Characteristics
1. Non-toxic, safe, odor-free, non-irritating, formaldehyde-free and other harmful gases are released and easy to clean;
2. the softness and hardness are adjustable, as well as the advantages of temperature resistance and elasticity;
3. low viscosity value, good spray and excellent bonding properties.
Classification
At present, vacuum plastics on the market are roughly divided into: PVC vacuum plastic, PET vacuum plastic, particle board
vacuum plastic, wooden door vacuum plastic.
Scope of application
It is widely used in vacuum plastic heat compounding of tangible parts, such as soft plastic materials such as polyvinyl
chloride (PVC) and vacuum forming of MDF, particle board, wood, etc. It is mainly used for wooden doors, cabinets,
speaker boards, computer tables, Vacuum forming of a car console or the like.
Precautions
Vacuum suction plastics should pay special attention to the following points during use, so as to avoid unnecessary waste
of resources.
Precautions
1st, to prevent freezing, the best storage conditions are above 5 °C;
2nd, do not mix with other different adhesives;
3rd , the addition of 3-5% curing agent can effectively improve the temperature resistance.
Operating process
Vacuum plastic is mainly used to bond computer desks, office desks, plastic doors, audio panels, cabinet panels and other
plastic panels (pieces), etc., and is widely accepted by the market for its excellent quality and excellent price. The rich
experience summarizes the operating process of vacuum plastic for reference.
The vacuum blister process consists of roughly twelve steps:
 

First, the preparation of materials: MDF
1. Ensure the surface of the board is clean.
For the cut MDF, when it is polished on the four sides, it should be sanded as fine as possible. In this way, in the
process of spraying, the four sides of the MDF will not cause uneven glue absorption due to the excessively rough
weight of the fiber, thereby causing pitting.
2. Precautions for selecting a composite film
2.l. According to the temperature requirements, choose the appropriate lamination. Different composite films have
different reactions to high temperatures. If materials are changed, they should be evaluated before operating conditions.
2.2. Use a composite film with a low plasticizer content as much as possible, because the plasticizer in the film may
liberate the surface during long-term storage and high temperature environment, thereby affecting the bonding effect.
2.3. For hard composite films: a shorter blister time and a relatively high blister temperature are recommended.
2.4. For soft composite films: a longer blister time and a relatively low blister temperature are recommended.
3. About the moisture content of MDF
3.1. Generally, the moisture content of MDF is controlled at 6% to 14%.
3.2. The best bonding conditions require the moisture content of the MDF to be controlled at 8% to 12%e.
4. Requirements for storage and mixing of adhesives and curing agents
4.1. Under normal circumstances, the production of vacuum plastic parts can be used to meet the requirements.
4.2. If the customer's heat resistance requirement of the finished product exceeds 70 °C or the temperature and
humidity of the production workshop are too high, it is recommended to use a curing agent. The curing agent is used in an
amount of 3% to 5%.
4.3. The ratio of the main agent to the curing agent must be accurately weighed.
4.4. The main agent and curing agent should be mixed evenly. It is recommended to stir the electric motor for at least 2
minutes.
4.5. Store in a cool place, storage temperature is not lower than 10 ° C
4.6. When the main agent and curing agent are not in use, the lid must be tightly closed, and the lid is ready to use. It is
not recommended to add water.
4.7. Do not mix with other adhesives
5. How to spray glue, how to determine the amount of glue sprayed
5.1. Spray glue should be even, contrast plane, side and uneven surface need double spray.
5.2. Generally, the amount of spray on the plane is 55-85g/m, and the amount of glue on the contour surface is 75-125
g/m.
6. Choice of plastic methods
Blistering methods are divided into two types: dry blistering and wet blistering.
7. The minimum activation temperature of the adhesive
The minimum activation temperature refers to the minimum temperature required to activate the adhesive property
during the blistering operation, corresponding to the temperature that can be achieved by the film layer, rather than the
set temperature of the machine! The glue is usually sucked. The higher the plastic temperature, the better the wetting of
the surface of the composite film by the film, which is advantageous for the bonding effect. However, customers tend to
consider the heat resistance of the composite film and reduce the plastic temperature.

 
8. Vacuum degree depends on conditions
The degree of vacuum depends on different plastic equipment, different composite film manufacturers, the thickness of
different composite films, the plastic temperature, the contour of the surface of the board, the position of the board, etc.
The customer should do the corresponding according to their actual situation. Adjustment.
9. Determinants of vacuuming time
9.l. The vacuuming time depends on: the hardness of the composite film, the plastic temperature, the profile of the
sheet, the degree of vacuum, etc., the customer should make corresponding adjustments according to their actual
conditions.
9.2. Under normal circumstances, according to experience, under the condition that the plasticizing temperature
reaches the minimum activation temperature of the adhesive and the composite film is fully softened, the vacuuming time
is: 5-30 seconds.
10. Pressure
According to experience, the pressure is usually about 2 to 18 kg/m.
10.1. For wet blister, the recommended pressure time is: 3-5 minutes.
10.2. For dry blister, the recommended pressure time is 2-3 minutes.
11. Pressure time requirements:
11.1. For wet blister, the recommended pressure time is: 3-5 minutes.
11.2. For dry blister, the recommended pressure time is 2-3 minutes.
12. Choice of spray gun caliber
12.l. Under normal circumstances, the diameter of the spray gun is: 1.5-2.5mm.
12.2. The diameter of the spray gun is less than 1.0mm. It is easy to block the nozzle during operation, which affects
the working efficiency; the diameter of the spray gun is large.
