Etanșantul semifluid, conform invenției, este caracterizat prin aceea că, 15 cuprinde: între 70 și 110 părți greutate rășină poliesterică cu grad mic de nesaturare, având un conținut în substanțe nevolatile de 97 ... 98%, indice de aciditate 10 mg KOH/g, viscozitate măsurată cu aparatul Hoppler, în 20 soluție 70% în stiren, la 25°C 300 mPa.s, între 25 și 55 p.g. materiale de umplutură anorganice ,alese dintre sulfat de bariu, carbonat de calciu, talc micronizat, azbest și mică, putând fi utilizați singuri, precum și în 25 amestec în orice proporție, între 1 și 6 p.g,. pigmenți organici, aleși dintre ftalocianină de cupru policlorurată având un indice de ulei de 41 g/100 g, greutate specifică 2,2 g/cm3 temperatura de descompunere mai mare de 30 200°C, ftalocianină de cupru halogenată cu greutate specifică 2,94 g/cm3, temperatură de descompunere mai mare de 200°C, indice de ulei 22 g/100 g și ftalocianină de cupru clorurată rezistentă la aromate cu greutate specifică 1,99/cm3, rezistență la temperatură mai mare ca 200°C, indice de ulei 28 g/100 g și pigmenți anorganici, aleși dintre oxid verde de crom, cu conținut în Cr2O3 de 99% indice de ulei 13 g/100 g, pigmenții putând fi utilizați singuri, precum și în amestecuri în orice proporție, între 0 și 4 p.g. și bioxid de siliciu coloidal cu xm conținut în SiO2 de 99,8%, pH în suspensie apoasă 4% de 3,4 ... 4,2.The semifluid sealant according to the invention is characterized in that 15 comprises: between 70 and 110 parts by weight polyester resin with low degree of unsaturation, having a non-volatile content of 97 ... 98%, acidity index 10 mg KOH / g, viscosity measured with Hoppler apparatus, in 20% solution in styrene, at 25 ° C 300 mPa.s, between 25 and 55 pg inorganic fillers, chosen from barium sulphate, calcium carbonate, micronized talc, asbestos and small, which can be used alone, as well as in 25 in any proportion, between 1 and 6 pg. organic pigments, selected from polychlorinated copper phthalocyanine having an oil index of 41 g / 100 g, specific weight 2.2 g / cm 3 decomposition temperature greater than 30 200 ° C, halogenated copper phthalocyanine with specific weight 2, 94 g / cm 3 , decomposition temperature greater than 200 ° C, oil index 22 g / 100 g and chlorinated copper phthalocyanine resistant to aromatics with specific weight 1.99 / cm 3 , temperature resistance greater than 200 ° C, oil index 28 g / 100 g and inorganic pigments, selected from chromium green oxide, containing in Cr 2 O 3 99% oil index 13 g / 100 g, the pigments can be used alone, as well as in mixtures. in any proportion, between 0 and 4 pg and colloidal silicon dioxide with xm contained in SiO 2 of 99.8%, pH in aqueous suspension 4% of 3.4 ... 4.2.
Aplicarea invenției conduce la următoarele avantaje:Application of the invention leads to the following advantages:
- etanșantul semifluid adeziv permanent este un produs omogen, care, în timp, nu prezintă fenomene de separare, la contactul cu uleiuri minerale și garnituri din hârtie, marsit, cauciuc NBR;- the permanent adhesive semifluid sealant is a homogeneous product, which, in time, does not exhibit separation phenomena, in contact with mineral oils and linings of paper, molded, NBR rubber;
- etanșantul semifluid prezintă caracteristici fizico-chimice și de utilizare comparative cu produsele existente pe piață;- the semifluid sealant has physico-chemical and use characteristics compared to the existing products on the market;
- etanșantul semifluid este realizat cu materii prime ieftine;- the semi-fluid sealant is made with cheap raw materials;
- etanșantul depozitat în condiții corespunzătoare are o stabilitate a proprietăților de minimum 2 ani;- the sealant stored under appropriate conditions has a stability of properties of at least 2 years;
- etanșantul a fost testat și se aplică industrial la S.C. Automobile Dacia Pitești din trim. IV 1989.- the sealant has been tested and is applied industrially in S.C. Automobiles Dacia Pitesti from the quarter. IV 1989.
Se dau în continuare 9 exemple de realizare a invenției, în care componentele sunt exprimate în părți în greutate.9 embodiments of the invention are given below, in which the components are expressed in parts by weight.
Etanșantul realizat conform exemplelor de mai sus se prepară astfel: materiile prime se dozează separat, se introduc rășina poliesterică și pigmenții într-un malaxor, se malazează timp de 10 ... 15 min, după care se 5 adaugă materialele de umplutură inclusiv bioxidul de siliciu coloidal. Se continuă malaxarea încă 30 ... 50 min până se obține un produs omogen. Acesta este omogenizat în continuare pe o mașină de frecat cu 3 valțuri, până atinge un grad de frecare de 3 ... 4 microni măsurat pe grindometrul Eriksen.The sealant made according to the above examples is prepared as follows: the starting materials are dosed separately, the polyester resin and the pigments are introduced into a mixer, the mixture is mixed for 10 ... 15 minutes, after which the filling materials including the dioxide dioxide are added. colloidal silicon. Continue mixing for another 30 ... 50 minutes until a homogeneous product is obtained. It is further homogenized on a 3-roll milling machine, until it reaches a friction degree of 3 ... 4 microns measured on the Eriksen grindometer.
Produsul final este un etanșant semifluid, având următoarele caracteristici:The final product is a semi-fluid sealant, having the following characteristics:
