Abstract
The invention discloses an environment-friendly emulsion paint used for glued board, which is prepared by copolymerizing the following raw materials by weight ratio: 800-900 parts of water, 30-50 parts of polyvinyl alcohol, monomer: 10-20 parts of acrylic acid, 450-500 parts of vinyl acetate, 20-40 parts of methyl acrylate, 20-40 parts of butyl acrylate, 350-450 parts of EVA emulsion, 4-8 parts of emulsifier, 30-45 parts of initiator, 40-50 parts of plasticizer, pH conditioning agent: 30-50 parts of sodium acetate solution with concentration of 15% and 40-60 parts of sodium bicarbonate solution with heavy concentration of 10%. According to the invention, each performance index reaches or exceeds the common white emulsion containing aldehyde, the emulsion paint has advantages of excellent water resistance and heat resistance performances, has characteristics of high bonding strength, fast drying speed, easy storage, long shelf-life, no pollution and the like, and can be widely used for industries of timber treatment, paint, building material, printing and the like.
Description
Technical field:
The present invention relates to adhesive field, being specifically related to a kind of environment-friendly type does not have the aldehyde white glue with vinyl.
Background technology:
Venamul; Claim white glue with vinyl again, because it produces advantages such as easy, easy to use; Be widely used in the bonding of material in the numerous areas such as wood working, adhering fabric, architectural decoration; Market is boundless, and its output is only second to urea-formaldehyde resin, occupies second in the production of tackiness agent with in using.Yet; Because product is Z 150PH and the condensation reaction of formaldehyde under acidic conditions of adopting in the venamul aborning mostly; So the formaldehyde that unavoidably contains hazardous substance in the product, use the back free formaldehyde to discharge, environment and human body are caused bigger harm.Enhancing along with scientific-technical progress and people's environmental consciousness has proposed requirements at the higher level to adhesive products, through copolymerization, blend, protective colloid modification obtain high-performance, pollution-free product has become inexorable trend.
Summary of the invention:
The technical problem that the present invention will solve provides wood veneer and uses environment-friendly type emulsion paint, does not contain free formaldehyde in the product, and adhesive property is excellent.
The present invention realizes through following technical scheme:
Wood veneer is used environment-friendly type emulsion paint, it is characterized in that being made by following raw materials in weight portion (the employing Z 150PH is a protective colloid) copolymerizing and blending: water 800-900, Z 150PH 30-50; Monomer: vinylformic acid 10-20, vinyl acetate between to for plastic 450-500, methyl acrylate 20-40; Bing Xisuandingzhi 20-40, EVA emulsion 350-450, emulsifying agent 4-8; Initiator 30-45; Softening agent 40-50, the PH regulator: weight concentration is 15% sodium acetate soln 30-50, heavy dense amount concentration is 10% sodium hydrogen carbonate solution 40-60;
Copolymerizing and blending comprises the following steps:
(a) water is added reaction kettle, be warming up to 28-32 ℃, under whipped state, add Z 150PH, be warming up to 95-98 ℃ then, and under this temperature, be incubated 1 hour;
(b) material with step (a) is cooled to 78-82 ℃, adds emulsifying agent, and then add sodium acetate soln, sodium hydrogen carbonate solution respectively is 1/2 of a total amount, stirred 25-35 minute;
(c) in the material of step (b), add 1/12 of initiator total amount again at 73-78 ℃; In 50-70 minute, drip 1/5 of monomer total amount then, reacted 30 minutes, add 1/9 of initiator total amount again; Dripped residual monomer then at 3-4 hour; During dripping residual monomer, added 1/14 of initiator total amount in per 30 minutes, drip off back insulation 80-100 minute;
(d) step (c) material is cooled to 65-75 ℃, adds softening agent, be cooled to 55-65 ℃ and add the EVA emulsion, be cooled to 45-55 ℃ again and add residue sodium-acetate, sodium hydrogencarbonate, continue to be cooled to below 40 ℃ and can pack.
Said emulsifying agent is one or both mixing of OP-10, sodium lauryl sulphate.
Said initiator is a kind of, two or three mixing of 6% ammonium persulphate, Potassium Persulphate or Sodium Persulfate solution.
Said softening agent is a kind of, two kinds, three kinds or four kinds of mixing of dimethyl phthalate, diethyl phthalate, Witcizer 300 or DOP.
Said Z 150PH is a kind of, two kinds three kinds or four kinds of mixing of Z 150PH 20-88,20-99,17-88,17-99 type.
Performance index of the present invention:
Solid content 40% ± 2%, cohesive strength 25-30mpa, boiling water boil and did not come unglued in 3 hours.
Each item performance index of the present invention all meet or exceed the common aldehyde white glue with vinyl that contains; Water tolerance, resistance toheat are superior; Have cohesive strength height, rate of drying fast, be prone to storage, long quality-guarantee period, characteristics such as pollution-free, can be widely used in industries such as wood working, coating, building materials, printing.
