Abstract
The present invention is one kind of modified emulsion with olefine monomers to change the after tackinese and the contamination resistance. The adoption of organic silicane coupling agent alters the hydrophilicity of the polymer and the adhesion to base material, and the adoption of sodium allyl hydroxypropyl sulfonate makes the prepared emuslion contain no free emulsifier and have high waterproof property, adhesion property and cement matching property. The emulsion is mainly used in facing paint of outer wall and may be also used in building adhesive, waterproof coating material, sealing glue, etc.
Description
The present invention relates to a kind of rubber-like cold cross-linking type pure acrylic acid lipin polymer emulsion, particularly a kind of pure acrylic acid lipin polymer emulsion of polymkeric substance being carried out the free emulsifying agent of nothing of modification by multiple alkene class functional monomer.
Pure acrylic acid lipin polymer emulsion has the ultraviolet essence of seeing through, and is specially adapted to outdoor use, so be mainly used in exterior coating at present.Existing domestic widely used ACRYLIC EMULSION exterior coating is usually because coating thickness reaches the low temperature brittleness (thermoplasticity) of emulsion polymer inadequately; half a year at least; 1 year 2 years at most; As time goes on; the crackle of filming that all occurs filming the spider reticulation be full of cracks in varying degrees or occur differing in size along with the cracking of body of wall sand-cement slurry, thus make the decoration defencive function of exterior coating be subjected to great influence.
The objective of the invention is to overcome weak point of the prior art, provide a kind of emulsion dry film to have elasticity and low temperature flexibility, and have simultaneously anti-after-tack, anti-ly stain, water-fast, high gloss and with the good elastic pure acrylic acid emulsion of cement compatibleness.
Technical scheme of the present invention is: elastic pure acrylic acid emulsion mainly is made up of vinyl monomer, initiator, buffer reagent and water.Vinyl monomer comprises acrylate, alkene class functional monomer.Improvements are, described alkene class functional monomer comprises vinyl cyanide, N hydroxymethyl acrylamide, (methyl) vinylformic acid, alkene class organo silane coupling agent, allyl group hydroxypropyl azochlorosulfonate acid sodium, and the per-cent that its content accounts for the emulsion gross weight is respectively 2-4%, 0.4-0.8%, 1-1.5%, 1.5-2% and 1-1.2%; The weight percent of all the other compositions is in the emulsion: acrylate 50-55%, sodium bicarbonate 0.1-0.2%, Potassium Persulphate 0.3-0.5%, water 39-41%.
The aforesaid propylene acid esters comprises soft monomer ethyl propenoate, butyl acrylate, Octyl acrylate or its mixture.
Among the present invention, owing to adopted alkene class functional monomer vinyl cyanide, N hydroxymethyl acrylamide, (methyl) vinylformic acid and alkene class organo silane coupling agent with cold cross-linking function and allyl group hydroxypropyl azochlorosulfonate acid sodium that emulsion polymer is carried out modification with emulsification function, thereby can further be cross-linked into reticulated structure after making the emulsion polymer film forming, change the wetting ability of polymkeric substance itself and the tack of base material.Owing to have the employing of the alkene class functional monomer allyl group hydroxypropyl azochlorosulfonate acid sodium of emulsification function, make not contain the free emulsifying agent in the emulsion that makes simultaneously.This emulsion is compared with present emulsion, dry film has good elasticity and low temperature flexibility, water tolerance and binding property all are significantly increased, and improved the compatibleness of emulsion and cement, exterior coating can be used for, fields such as architecture adhesion agent, waterproof coating material, seal gum, modified cement and concrete repair can be used for again.
The prescription that further specifies embodiments of the invention is below formed (weight percent):
Embodiment one: ethyl propenoate 53; Vinyl cyanide 2.5; N hydroxymethyl acrylamide 0.6; Vinylformic acid 1.3; Alkene class organo silane coupling agent 1.5; Allyl group hydroxypropyl azochlorosulfonate acid sodium 1; Sodium bicarbonate 0.1; Potassium Persulphate 0.4; Water 39.6.
Embodiment two: butyl acrylate 51; Vinyl cyanide 4:N-n-methylolacrylamide 0.6; Vinylformic acid 1.3; The organic alkane coupling agent 2 of alkene class; Allyl group hydroxypropyl azochlorosulfonate acid sodium 1; Sodium bicarbonate 0.1; Potassium Persulphate 0.4; Water 39.6.
Embodiment three: ethyl propenoate 35; Octyl acrylate 16; Vinyl cyanide 4; N hydroxymethyl acrylamide 0.6; Vinylformic acid 1.3; Alkene class organo silane coupling agent 2: allyl group hydroxypropyl azochlorosulfonate acid sodium 1; Sodium bicarbonate 0.1; Potassium Persulphate 0.4; Water 39.6.
Claims (2)
