Abstract
Description
DESCRIEREDESCRIPTION
Invenția se referă la un procedeu de obținere a unor polimeri adezivi în soluție, destinați aplicării pe diferite suporturi, pentru realizarea de confecții și ambalaje din material lemnos.The invention relates to a process for obtaining adhesive polymers in solution, intended for application on different substrates, for making confections and packaging of wood material.
Sunt cunoscute procedee de obținere a adezivilor prin polimerizare în soluție de solvenți organici a unor amestecuri de esteri etillenici nesaturați cu mai mult de 5 atomi de carbon în moleculă, cu esteri ai acidului acrilic cu mai puțin de 3 atomi de carbon în partea acidă a moleculei și nu mai mult de 2 atomi de carbon în gruparea alcailică, un monomer vinilic cu grupare carboxilică cu atom he hidrogen labil în moleculă și/sau esteri amidici sau glicilidici ai unui acid nesaturat monocarboxilici. Primele două componente dau caracterul de adezivi sensibili la presiune, în timp ce, reticularea și coeziunea internă a polimerului sunt conferite de celelalte componente.Processes for obtaining the adhesives by polymerization in solution of organic solvents of mixtures of unsaturated ethylene esters with more than 5 carbon atoms in the molecule, with esters of acrylic acid with less than 3 carbon atoms in the acidic part of the molecule are known. and not more than 2 carbon atoms in the alkyl group, a hydrogen-labile carboxylic group vinyl monomer and / or amide or glycidyl esters of a monocarboxylic unsaturated acid. The first two components are pressure sensitive adhesives, while the cross-linking and internal cohesion of the polymer are conferred by the other components.
Ca solvenți se utilizează hidrocarburi, cum ar fi toluen; benzen; esteri, cum ar fi acetat de etil; cetone, cum ar fi acetonă, metiletilcetonă, ciclohexanonă, alcooli alifatici, cum ar fi alcool izopropilic, alcool terțbutilic.Hydrocarbons such as toluene are used as solvents; benzene; esters such as ethyl acetate; ketones, such as acetone, methylethylketone, cyclohexane, aliphatic alcohols, such as isopropyl alcohol, tert-butyl alcohol.
în scopul de a facilita obținerea de anumite mase moleculare pentru produsul polimerizat în funcție de destinația lui ca adeziv, se pot folosi regulatori de creștere a catenei macromoleculare.In order to facilitate the obtaining of certain molecular masses for the polymerized product depending on its destination as an adhesive, macromolecular chain growth regulators can be used.
Dezavantajul acestor procedee este că, pentru conținutul ridicat în substanță solidă cerut pentru proprietăți, ele duc la produse cu viscozitate mare, improprie sistemelor de aplicare, cum ar fi rolă, lamă de aer, pulverizare și ca urmare, necesită consum mare de solvenți pentru diluare, ceea ce reprezintă un pericol crescut de inflamabilitate, un consum energetic sporit pentru uscare.The disadvantage of these processes is that, for the high solids content required for properties, they lead to high viscosity products, inappropriate for application systems, such as roller, air blade, spray and as a result, require high solvent consumption for dilution. , which represents an increased danger of flammability, increased energy consumption for drying.
Problema pe care o rezolvă invenția este realizarea unei reacții de polimerizare radicalică în soluție de solvenți organici în amestec, cu adaos treptat al sistemului de inițiere, în vederea obținerii unui polimer adeziv cu viscozitate reglabilă, corespunzătoare sistemului de aplicare pe suport, la un conținut ridicat în substanță solidă.The problem solved by the invention is to perform a radical polymerization reaction in solution of mixed organic solvents, with the gradual addition of the starting system, in order to obtain an adhesive polymer with adjustable viscosity, corresponding to the application system on the substrate, at a high content. in solid substance.
Procedeul de obținere a unor polimeri adezivi în soluție, conform invenției, înlătură dezavantajul menționat, prin aceea că se polimerizează în 60...80 părți amestec de solvenți, format din acetat de etil / alcool izopropilic în raport gravimetric 1/1...3/1 pentru un conținut în substanță solidă de maxim 70%, un amestec de comonomeri constituit din acrilat de 2-etilhexil, acrilat de butii, metacrilat de 2-etilhexil, acetat de vinii, acid acrilic, în prezență de 0,4-0,6 părți peroxid de benzoil ca inițiator radicalic adăugat treptat în timpul reacției, părțile fiind exprimate în greutate; amestecul <V 2 ο 15 - - 00538de comonomeri este format din 50-70% părți acrilat de 2-etilhexil, 20...40 părți acetat de vinii, 5 părți acid acrilic, părțile fiind exprimate în greutate.The process of obtaining adhesive polymers in solution, according to the invention, removes said disadvantage, by polymerizing in 60 ... 80 parts solvent mixture, consisting of ethyl acetate / isopropyl alcohol in gravimetric ratio 1/1 ... 3/1 for a solids content of up to 70%, a comonomer mixture consisting of 2-ethylhexyl acrylate, butyl acrylate, 2-ethylhexyl methacrylate, vinyl acetate, acrylic acid, in the presence of 0.4- 0.6 parts benzoyl peroxide as a radical initiator added gradually during the reaction, the parts being expressed by weight; The mixture <V 2 ο 15 - - 00538 of comonomers consists of 50-70% parts acrylate of 2-ethylhexyl, 20 ... 40 parts vinyl acetate, 5 parts acrylic acid, the parts being expressed by weight.
Amestecul de comonomeri este format din 50-60 părți acrilat de butii, 10...15 părți acrilat de 2-etilhexil, 10...15 părți acetat de vinii și 5 părți acid acrilic, părțile fiind exprimate în greutate;The comonomer mixture consists of 50-60 parts butyl acrylate, 10 ... 15 parts 2-ethylhexyl acrylate, 10 ... 15 parts vinyl acetate and 5 parts acrylic acid, the parts being expressed by weight;
Procedeul conform invenției prezintă următoarele avantaje:The process according to the invention has the following advantages:
- Este simplu de realizat pe instalații existente;- It is simple to do on existing installations;
- Decurge la conversie crescută;- It results in increased conversion;
- Duce la un produs cu viscozitate relativ mică, potrivită sistemului de aplicare pe suport, pentru un conținut în substanță solidă ridicat;- It leads to a product with relatively low viscosity, suitable for the application system on the substrate, for a high solid content;
- Nu necesită faza finală de diluare a produsului.- Does not require the final dilution phase of the product.
