Description
Technical field
The present invention relates to PVB laminated glass field of deep, more particularly, to a kind of air guide agent, preparation method and its liquid
Method for exhausting.
Background technique
PVB is one kind of laminated glass intermediate coat, its main feature is that toughness height is good, the laminated glass of preparation is chiefly used in anti-machine
In the building and venue of tool impact.PVB film full name be polyvinyl butyral film, be using about 75% PVB resin and
25% plasticizer and other a small amount of substances.
PVB film bonding mechanism: the hydrogen bond between the COH base in glass SiOH and film forms bonding force；In film
Potassium ion displaces hydrogen from glass, to have preferable bonding force.
PVB is dry-method laminated glass intermediate coat, currently, dry lamination uses dry method to be vented, in the prior art, is met
The solution and limitation that glass is felt suffocated are as follows:
(1) temperature control method finds tail portion not edge sealing and the heated meet demand of film by reducing the temperature of roll-in furnace.
Its limitation is: glass thin can be used this method, but glass is thicker or the film number of plies is difficult to find or not deposit
In equalization point, it is finally unable to roll-in production.
(2) glass is put into vacuum bag by vacuumizing method using vacuum degassing production technology, in high-temperature high-pressure state
It persistently vacuumizes, has the function that exhaust；But its production efficiency and production cost are significantly increased, and limit its a wide range of popularization.
(3) capillary trachea degassing method forms gas circuit in the glass tail portion side's of burying tracheae in advance, and gas is logical when roll-in
Cross gas circuit exclusion.Its limitation has two o'clock, i) tracheae only point exhaust, it can only accomplish that exhaust gas density increases increasing tracheae
Add, between the tubes or there can be bubble；Ii pipe will remove after) being vented, this position does not have edge sealing after removing pipe, in autoclave rank
The anti-gas of section meeting causes bubble.Solution can only add stifled film clast edge and be clamped using external force, but in glass later period use process
Middle clamping position can come unglued, once coming unglued, (expand with heat and contract with cold, the steam in air is viscous into causing to lose in glass respiration
Connect performance) under the more will open the more big, cause glass to lose security performance.
(4) glass tail portion film applicator coating pastes the film not being bonded, limitation or and capillary trachea row in glass tail portion
Gas method problem is the same, needs autoclave stage gripping.
Summary of the invention
The problem to be solved in the present invention is to provide liquid air guide agent, preparation method and its exhaust liquid methods, using the liquid
Body air guide agent can accelerate the process of PVB laminated glass processing technology, and reduce rejection rate.
To solve the technical problem in background technique, the technical solution adopted by the present invention is that:
A kind of air guide agent consists of the following compositions by percentage to the quality:
Triethylene glycol diethyl caprylate, 97.5-99%；
Water, 1-2.5%；
The sum of each component mass percent is 100%.
In addition, the present invention also resides in the open exhaust liquid method using above-mentioned air guide agent, including following key step:
(1) tile bottom glass；
(2) away from smearing air guide agent at glass tail edge position 100-300mm；
(3) PVB film is spread, in every layer of film away from smearing air guide agent at the 100-300mm of tail edge position；
(4) upper layer glass is covered, laminated glass unit is formed；
(5) into roll-in furnace roller pressure.
It should be noted that the liquid in laminated glass exhaust liquid method expects water first, but film has water imbibition, roller
Tail portion film moisture content is exceeded after pressure, and adhesive property is caused to reduce；Grease type material such as edible oil, lubricating grease, although solving
Moisture content problem, but its own becomes permanent separation layer, causes film not be bonded with glass, loses original meaning
Justice；Alcohols material such as ethyl alcohol can solve moisture content and permanent sequestration problem, but alcohols material is equivalent to and dilutes bonding key
Density, cannot be tested by the shock resistance of " GB 15763.3-2009 safety glass for building ".
Air guide agent must have following features thus: cannot reduce film adhesive property, preferably mutually melt with film, it is necessary to meet
Liquid fluidity feature under relevant temperature cannot destroy film structure.
The formula and its respective action that air guide agent of the invention determines as a result, are as follows: triethylene glycol diethyl caprylate promotes
PVB is Nian Jie with glass；Because the adhesive property between PVB itself and glass is preferable, it is therefore not necessary to which coupling agent, which is added, can be realized
PVB is Nian Jie with glass.And PVB main component is polyvinyl butyral, the main component of triethylene glycol diethyl caprylate and the PVB
It is close, avoid the occurrence of incompatible problem.
Common laminated glass intermediate coat is ion and glass middle-jiao yang, function of the spleen and stomach there are also SGP, this SGP film essence Nian Jie with glass
Ion and hole, which are mutually embedded in, forms ionic bonding, poor compared with the adhesive property between PVB and glass, therefore, if the interlayer
Middle membrane of glass is SGP, needs that coupling agent is added in air guide agent, to improve its adhesive property.
When the key point of exhaust liquid, in roll-in, liquid level is formed between film and film, film and glass, is prevented
In roll temperature, several interfaces stick together, and the air inside laminated glass is allowed to exclude by liquid level.It is extra simultaneously to lead
Gas agent is squeezed out by pressure roller again.Remaining minimal amount of air guide agent can interpenetrate promotion with film in the sandwich-glass high-pressure kettle stage
Film is bonding with glass.
Therefore air guide agent not only addresses only the problem of PVB laminated glass is felt suffocated, but also it is Nian Jie with glass to promote film
Ability.
Beneficial effects of the present invention:
(1) component of air guide agent is simple, and in view of the consistency problem of air guide agent and glass material, PVB film, especially
Use triethylene glycol diethyl caprylate；
(2) it applies and is the advantages of exhaust liquid method: without increasing solid matter in glass tail portion, not increasing solid matter
With regard to not being related to the not edge sealing problem after taking out；And most liquid exclude under the pressure of pressure roller；It illustrates, uses
Exhaust liquid method of the invention, (specific pressure is with roll squeezer type and pressure roller than normal pressure increase 10-20% for platen pressure
Depending on material), convenient for by extra fluid removal；
(3) exhaust liquid method is not necessarily to that high temperature can be used and quickly produce and process mode by temperature balance-seeking point, according to
For 6G/1.52/6G structure roll-in furnace, former 550-600 DEG C of temperature of roll-in furnace 2# furnace radiating pipe, several 2.2-2.4 ms/min are walked,
Using exhaust liquid method, roll-in furnace 2# furnace radiating pipe temperature can be set as 650-700 DEG C, walk between several 2.8-3.5 (specific root
Adjusted according to pressing effect), such production efficiency can promote 20% or more.
