Abstract
The invention discloses a polyvinyl butyral adhesive and a preparation method thereof. The adhesive comprises the following components in parts by weight: 40-50 parts of polyvinyl alcohol, 30-55 parts of aldehyde, 15-20 parts of concentrated sulfuric acid, 7-12 parts of a silane coupling agent, 25-30 parts of filler and 2-4 parts of diluents. The polyvinyl butyral adhesive has the beneficial effect that the polyvinyl butyral adhesive is good in binding power, moisture-proof and anticorrosive, the binding power is increased due to the added coupling agent, and the production cost is reduced due to the added filler and diluent without influencing the adhesion effect of the polyvinyl butyral adhesive.
Description
Technical field
The present invention relates to a kind of preparation method of tackiness agent, relate in particular to glutinous agent of a kind of butvar adhesive and preparation method thereof.
Background technology
The features such as splicing (bonding, bonding, cementing, gluing) refers to the technology that homogeneity or heterogeneous body surface link together with sizing agent, has stress distribution continuous, lightweight, or sealing, and most technological temperatures are low.Glued joint the connection that is specially adapted to unlike material, different thickness, ultra-thin specification and complex component.Glued joint RECENT DEVELOPMENTS the fastest, application industry is very extensive.Along with the proposition in succession of the various gluing theories of 20 middle of century, and the deep progress of the basic research work such as sizing agent chemistry, sizing agent rheology and gluing failure mechanisms, make sizing agent performance, kind and application have the development of advancing by leaps and bounds.At present, the glutinous agent of the butvar adhesive produced is generally that polyethylene alcohols and aldehydes generates under acidic substance, and cost is high, therefore, needs a kind of new technical scheme to address the above problem.
Summary of the invention
The invention provides glutinous agent of a kind of butvar adhesive and preparation method thereof.
The technical solution used in the present invention: the glutinous agent of a kind of butvar adhesive comprises each composition of following weight part: the polyvinyl alcohol of 40-50 part, the acetaldehyde of 30-55 part, the vitriol oil of 15-20 part, the silane coupling agent of 7-12 part, the filler of 25-30 part, the thinner of 2-4 part.
Above-mentioned silane coupling agent is one or more the mixture of KH550, KH560 and KH570; Above-mentioned filler is one or more mixture of calcium carbonate, barium sulfate and aluminium powder; Above-mentioned thinner is one or both of acetone, toluene.
The preparation method of the glutinous agent of a kind of butvar adhesive is: according to above-mentioned weight part, in the mixture of polyvinyl alcohol and acetaldehyde, add the vitriol oil, temperature setting is set to 70-90 ℃, generate polyvinyl butyral acetal, filter out product, previous step is produced polyvinyl butyral acetal and silane coupling agent, filler and thinner add in stirrer and stir successively, the stirring velocity that stirrer is set is 1500-2700r/min, churning time is 40-50min, generates finished product.
Beneficial effect of the present invention: the glutinous agent cohesive force of butvar adhesive is good, moisture resistance, anticorrosion, and the coupling agent of interpolation has increased cohesive force, the filler of increase and thinner, in the gluing effect that does not affect the glutinous agent of butvar adhesive, have reduced production cost.
