Description
Technical field
The invention belongs to plasticizer field, it is related to a kind of composite elasticizer and its preparation method and application.
Background technology
Food containers, in particular for holding the food glass bottle of all kinds of fruit, pickles, wine, honey etc., in order to ensure glass
The leakproofness of glass bottle moulds technique application liquid sealant, heating modeling generally in the injecting glue slot or bottle cap of its bottle cap by drop
Formed after change has certain adhesive force and flexible sealing ring to bottle cap, plays sealing and antisepsis.Traditional bottle cap is close
Sealing is equipped with phthalic ester plasticizer and various auxiliary agents using PVC paste resin as primary raw material.Due to adjacent benzene two
Formate ester is the main source for causing environmental hormone effects, using phthalic acid esters class as the food bottle cap sealing of plasticizer
There is health and seriously endanger, put into effect in succession in relation to the environmental regulation to phthalic acid esters class plasticizer in glue.Also,
In order to effectively prevent risk, not only strictly forbid to use phthalic acid esters class at present in the world, but also for containing benezene, epoxy
Class and other oiliness objects strictly limit their amounts of moving out in sealing ring.To overcome China's food export packing technique bottle
Neck, nearly ten years, domestic industry are being dedicated to developing the polyvinyl chloride sealant of non-phthalic acid ester class always.
CN102311592 is disclosed using PVC paste resin as primary raw material, is plasticising with tributyl 2-acetylcitrate
Agent, dilatancy microballoon are foaming agent and are aided with the polyvinyl chloride sealant of the combinations such as antifoaming agent, heat stabilizer.It is well known that second
Primary plasticizer less effective of the acyl tributyl citrate as polyvinyl chloride, and high-foaming can influence the attachment of sealing ring and substrate
Power, to influence the sealing performance of sealing ring.
In conclusion polyvinyl chloride sealant is in addition to that must have the traditional performances such as certain adhesive force, elasticity and flatness
Outside, move out amount of the oiliness object in fluid sealant must also reach international advanced standard.Meanwhile the viscosity of fluid sealant must also expire
The processing request of sufficient rotational forming, therefore, it is necessary to develop a kind of composite elasticizer to meet the requirement of polyvinyl chloride sealant.
Invention content

Suddenly in the mixture that (1) obtains, 25-35min is mixed with the stir speed (S.S.) of 1000-1200r/min, obtains the compound plasticising
Agent.
The third aspect, the present invention provides a kind of polyvinyl chloride sealant, the polyvinyl chloride sealant includes such as first
Composite elasticizer described in aspect.
Preferably, the polyvinyl chloride sealant can be used as bottle cap sealant.
Composite elasticizer provided by the invention has good speedup effect, and has low oily matter emigration,
When the plasticizer as polyvinyl chloride, obtained polyvinyl chloride sealant reaches food-grade application requirement, and it is close to can be used as bottle cap
Sealing uses.
Compared with the existing technology, the invention has the advantages that：
(1) use epoxidized soybean oil as primary plasticizer, the tributyl 2-acetylcitrate of addition, dioctyl terephthalate
Plasticization is equally played with polyester, four are used cooperatively, and the composite elasticizer that the present invention obtains can be made to have and preferably increased
Effect is moulded, the flexibility of polyvinyl chloride can be increased considerably；
(2) pentaerythrite have hydroxyl, with epoxidized soybean oil, tributyl 2-acetylcitrate, dioctyl terephthalate and
It can form hydrogen bond between polyester, in this way can be precipitated to avoid molecule and oily matter is moved out；
(3) addition of dimethicone can make up epoxidized soybean oil, tributyl 2-acetylcitrate etc. and molecular weight of polyesters
The deficiency to differ greatly makes molecular weight have certain continuity, above-mentioned plasticizer can be made to squeeze into polyvinyl chloride molecular gap,
It can be more advantageous to absorption of the polyvinyl chloride for plasticizer, so that the polyvinyl chloride sealant arrived has better effect；
(3) when composite elasticizer provided by the invention is plasticized for polyvinyl chloride, obtained polyvinyl chloride sealant is reachable
To the other requirement of food-grade, it can be used as bottle cap sealant.
