Description

A kind of anticorrosive wear-resistant container aqueous sealant and preparation method thereof
Technical field
The present invention relates to fluid sealant technical field, more particularly, to a kind of anticorrosive wear-resistant container aqueous sealant and its system Preparation Method.
Background technology
Fluid sealant is to guide to deform with sealing surface shape, is difficult to trickle, has the encapsulant of certain caking property, be used to Filling configuration gap, to play the adhesive of sealing function, play important in multiple fields such as building, assembling, transportation Effect.In recent years, developing rapidly with Container Transport industry, fluid sealant is as the main auxiliary material during Production Container Material, its serviceability is also more paid attention to.Container seals conventionally used solvent-borne type butyl type rubber or neoprene Class fluid sealant, such fluid sealant abnormal smells from the patient weight, VOC emission amount are big, may result in environmental pollution, or even produce injury to human body, Environmental requirement cannot be met.Aqueous sealant, as a kind of environmentally friendly product, increasingly receives universal paying close attention to.
Acrylic emulsion has the characteristics that caking property is strong, weatherability is high, application property good, becomes the good choosing of aqueous sealant Select.CN201410684697 discloses a kind of automobile water-based property acrylic sealant, has excellent sealing, weatherability and storage Deposit stability, VOC emission amount is low, environmental protection.However, the intensity of this fluid sealant and pliability deficiency are it is impossible to adapt to existing For the high request to fluid sealant serviceability for the container, need to improve further.
Content of the invention
The object of the invention is exactly the defect in order to make up prior art, provides one kind to have high intensity, high-flexibility and excellent concurrently Good sealing property, the anticorrosive wear-resistant container aqueous sealant of good endurance, long service life and environmental protection and its system Preparation Method.
The present invention is achieved by the following technical solutions:
A kind of anticorrosive wear-resistant container aqueous sealant, it is to be obtained by the raw material of following weight parts:
Solid content is the aqueous acrylic emulsion 40-60 of 40-50%, and solid content is the polythene wax emulsion 3-5 of 30-40%, nanometer Silicon nitride 3-5, silica flour 40-50, hydroxyethyl cellulose 1.5-2.5, soybean protein 2-4, Tween-80 0.5-1, sterilization Preservative BIT 0.3-0.5, dimethicone 0.3-0.5, triethanolamine borate 0.5-1, water 10-15.
A kind of preparation method of anticorrosive wear-resistant container aqueous sealant, comprises the following steps:
(1)Weigh raw material by weight, first soybean protein and Tween-80 are added to the water 60-80 DEG C of stirring 0.5-1h, cooling Add aqueous acrylic emulsion and polythene wax emulsion stirring 10-15min afterwards, obtain complex emulsions;
(2)Hydroxyethyl cellulose is compared 1 by solid-liquid weight:30-1:50 add 60-80 in the acetum that mass fraction is 4-6% DEG C stirring 2-4h, after cooling, pH is adjusted to neutrality, be subsequently adding silica flour and nano-silicon nitride stirring 0.5-1h, be dried after grind Uniformly, obtain modified filler;
(3)By step(1)In complex emulsions and step(2)In modified filler mix under the conditions of 1000-1200r/min Stirring 10-15min, is subsequently adding remaining raw material mix homogeneously, obtains final product anticorrosive wear-resistant container aqueous sealant.
It is an advantage of the invention that:
The present invention carries out surface coating modification using hydroxyethyl cellulose to filler, has both enhanced filler and aqueous acrylic emulsion Between adhesion, synergism can be played with soybean protein again, improve pliability and the intensity of aqueous sealant, then pass through its Remaining raw material compounding so as to get aqueous sealant have high intensity, high-flexibility and excellent sealing property, bonding effect concurrently Well, durability height, long service life and environmental protection, also good wear-resisting, decay resistance simultaneously, are suitable for packaging Case field.
Specific embodiment
A kind of anticorrosive wear-resistant container aqueous sealant, is prepared from by the component raw material of following weight (kg):
Solid content is 40% aqueous acrylic emulsion 40, and solid content is 30% polythene wax emulsion 3, nano-silicon nitride 3, quartz Powder 40, hydroxyethyl cellulose 1.5, soybean protein 2, Tween-80 0.5, sterilization antiseptic BIT 0.3, dimethicone 0.3, triethanolamine borate 0.5, water 10.
A kind of preparation method of anticorrosive wear-resistant container aqueous sealant, comprises the following steps:
(1)Weigh raw material by weight, first soybean protein and Tween-80 are added to the water 60 DEG C of stirring 0.5h, add after cooling Enter aqueous acrylic emulsion and polythene wax emulsion stirring 10min, obtain complex emulsions;
(2)Hydroxyethyl cellulose is compared 1 by solid-liquid weight:30 add 60 DEG C of stirring 2h in the acetum that mass fractions are 4%, After cooling, pH is adjusted to neutrality, is subsequently adding silica flour and nano-silicon nitride stirring 0.5h, grinds uniformly after being dried, obtain modified filling out Material;
(3)By step(1)In complex emulsions and step(2)In modified filler mixing under the conditions of 1000r/min stir 10min, is subsequently adding remaining raw material mix homogeneously, obtains final product anticorrosive wear-resistant container aqueous sealant.
