Abstract
The invention discloses dustproof stain-resistant container water-based sealant. The dustproof stain-resistant container water-based sealant is prepared from, by weight, 40-60 parts of water-based acrylic emulsion with the solid content being 40-50%, 5-10 parts of water-based fluorine carbon emulsion with the solid content being 40-50%, 1.5-2.5 parts of hydroxyethyl cellulose, 20-30 parts of wollastonite powder, 20-30 parts of talcum powder, 2-4 parts of soyabean protein, 0.5 -1 part of polysorbate-80, 0.3-0.5 part of antibacterial preservative BIT, 0.5-1 part of methyl phenyl silicone oil, 0.1-0.15 part of nonylphenol polyoxyethylene ether and 10-15 parts of water. The water-based sealant has high strength, high suppleness and excellent sealing performance at the same time and is good in bonding effect, high in durability, long in service life and green and environmentally friendly; and meanwhile, the water-based sealant has good dustproof performance, dampproof performance and stain-resistant performance and is applicable to the field of containers.
Description
Technical field
The present invention relates to fluid sealant technical field, more particularly to a kind of dust-proof stain resistant container aqueous sealant and its system
Preparation Method.
Background technology
Fluid sealant be guide deform with sealing surface shape, be difficult trickling, have the encapsulant of certain caking property, be for
Filling configuration gap, the adhesive to play sealing function, play important in multiple fields such as building, assembling, transportation
Effect.In recent years, developing rapidly with Container Transport industry, fluid sealant as Production Container during main auxiliary material
Material, its performance are 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 is increasingly paid close attention to by universal as a kind of environmentally friendly product.
Acrylic emulsion has the characteristics of caking property is strong, weatherability is high, application property is good, becomes the good choosing of aqueous sealant
Select.CN201410684697 discloses a kind of automobile water-based property acrylic sealant, with excellent sealing, weatherability and storage
Stability is deposited, VOC emission amount is low, environmental protection.However, the intensity of this fluid sealant and pliability are not enough, it is impossible to adapt to existing
For high request of the container to fluid sealant performance, need further to improve.
The content of the invention
The object of the invention is exactly for the defect for making up prior art, there is provided one kind has high intensity, high-flexibility and excellent concurrently
Good sealing property, the dust-proof stain 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 dust-proof stain resistant container aqueous sealant, which is obtained by the raw material of following weight parts：
Aqueous acrylic emulsion 40-60 of the solid content for 40-50%, water-base fluorocarbon emulsion 5-10 of the solid content for 40-50%, hydroxyl second
Base cellulose 1.5-2.5, wollastonite in powder 20-30, Pulvis Talci 20-30, soybean protein 2-4, Tween-80 0.5-1, sterilization
Preservative BIT 0.3-0.5, methyl phenyl silicone oil 0.5-1, NPE 0.1-0.15, water 10-15.
A kind of preparation method of dust-proof stain resistant container aqueous sealant, comprises the following steps：
（1）Raw material is weighed by weight, and soybean protein and Tween-80 are added to the water into 60-80 DEG C of stirring 0.5-1h, cooling first
Aqueous acrylic emulsion, water-base fluorocarbon emulsion stirring 10-15min are added afterwards, obtain complex emulsions；
（2）Hydroxyethyl cellulose is compared into 1 by solid-liquid weight:30-1:50 add mass fraction for 60-80 in the acetum of 4-6%
PH is adjusted to neutrality after cooling, is subsequently adding wollastonite in powder, Pulvis Talci stirring 0.5-1h by DEG C stirring 2-4h, and after being dried, grinding is equal
It is even, 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 dust-proof stain resistant container aqueous sealant.
It is an advantage of the invention that：
The present invention carries out surface coating modification to filler using hydroxyethyl cellulose, has both enhanced filler and aqueous acrylic emulsion
Between adhesion, synergism can be played with soybean protein again, improve the pliability and intensity of aqueous sealant, then by which
The compounding of remaining raw material, so as to get aqueous sealant have high intensity, high-flexibility and excellent sealing property, bonding effect concurrently
Good, durability height, long service life and environmental protection, while also good dust-proof, moistureproof, contaminated resistance, is adapted to use
In container field.
Specific embodiment
