Abstract
The invention relates to a formula for modifying adhesive properties of polyvinyl chloride (PVC) soft products by using chlorinated polyethylene, belonging to the technical field of PVC soft products. The invention aims to solve the technical problem that the ASA (acrylonitrile-styrene-acrylate)/PVC coextruded profile small-molecule soluble plasticizer can easily precipitate and corrode the ASA colored surface. The technical scheme is as follows: the chlorinated polyethylene accounts for 30-60 wt% of the PVC. By reasonably proportioning the chlorinated polyethylene and PVC, the chlorinated polyethylene with adhesive, coating and bonding properties is utilized to provide favorable adhesive properties for the PVC soft material at processing temperature and firmly attach the PVC soft material to the plastic profile by a coextrusion technique. The small-molecule plasticizer is limited and immobilized to prevent the phenomena of dissolution adhesiveness to the ASA colored surface and swelling to the PVC surface due to the transfer of the small-molecule plasticizer.
Description
Technical field
The formula of a kind of chlorinated polyethylene modified polyvinyl chloride soft goods adhesiveproperties of the present invention, belongs to polyvinyl chloride soft goods technical field.
Background technology
In the development of plastic-steel section bar, along with improving constantly of people's demand, the technology such as section bar overlay film, spraying, ASA co-extrusion that engender are to meet people to door and window colorize, personalized demand.And raising energy-conserving and environment-protective required along with people, also occur that adhesive tape co-extrusion section bar improves into watertightness and the resistance to air loss of window.Have at the same time in the production and application process of ASA co-extrusion and adhesive tape co-extrusion section bar and find, window is closed along with migration of plasticizer, volatilization, erosion in adhesive tape for a long time, and adhesive tape and the colour plane window that is sticked together is difficult to open, and affects the use of user.
Adhesive tape co-extrusion section bar will reach into window watertightness, bubble-tight raising, and coextrusion rubber strip must bondingly with section bar firmly not to come off.In prior art, main dependence has the small molecules softening agent of solvency action to complete the bonding of adhesive tape and section bar to PVC.Such as dimethyl phthalate etc. just have dissolution phenomena clearly to PVC at normal temperatures, just more easily bondingly with section bar when co-extrusion firmly not to come off.But easily separate out at this part small molecules softening agent when the later stage uses and corrode the color face of ASA, cause when window is not opened for a long time sash to open difficulty.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, and technical problem to be solved is that the problem corroding the color face of ASA easily separated out by ASA/PVC co-extrusion section bar small molecules solvability softening agent.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of formula of chlorinated polyethylene modified polyvinyl chloride soft goods adhesiveproperties, and the consumption of employing chlorinatedpolyethylene chlorinatedpolyethylene is the 30-60% of PVC quality.
As preferred example, following formula can be selected:
PVC 35~40
DOP 20~30
DBP 0.2~13.5
Stablizer 1.6 ~ 2.1
Inorganic filler 5 ~ 20
Chlorinatedpolyethylene 12 ~ 21
Those skilled in the art can also according to needs of production, some stearic acid of suitable interpolation and toner.
Up to now, the chlorinatedpolyethylene of all trades mark can both be used for formula of the present invention, and plays corresponding effect.
Compared with prior art the present invention has following beneficial effect: the novelty teabag providing chlorinatedpolyethylene, and usual chlorinatedpolyethylene is as the anti-impact modifier, fusing assistant etc. of PVC; The present invention is by the rational proportion of chlorinatedpolyethylene and PVC, utilize the cementability of chlorinatedpolyethylene, covering property and bonding performance, at processing temperatures for PVC soft material provides good adhesiveproperties, PVC soft material is firmly bonded on plastic irregular profile by co-extrusion technology; Small molecules softening agent is fixed simultaneously, prevent small molecules migration of plasticizer to the color molten sticky phenomenon in face of ASA and the Swelling to PVC face.
Various starting material are carried out batch mixing, extruding pelletization by processing requirement by using method: the consumption of reference formulation on request.Sizing material particle on plastic irregular profile, can form co-extrusion section bar by sizing material co-extrusion machine co-extrusion.
