Abstract
Description
Invenţia se referă la materiale de construcţie, în special la compoziţiile termoizolante pentru construcţie, şi poate fi utilizată pentru izolarea termică şi acustică a pereţilor, planşeelor şi structurilor portante ale clădirilor cu diversă destinaţie, precum şi pentru izolarea termică a traseelor termice, cuptoarelor, cazanelor, boilerelor şi altor dispozitive. The invention relates to construction materials, in particular to thermal insulation compositions for construction, and can be used for thermal and acoustic insulation of walls, floors and load-bearing structures of buildings for various purposes, as well as for thermal insulation of heat pipes, furnaces, boilers, water heaters and other devices.
Este cunoscut un material termoizolant, care conţine, % mas.: în calitate de antiseptic - borax 5,5…6,5, în calitate de antipiren - acid boric 10,5…11,5, şi fibre lemnoase - restul [1]. A thermal insulation material is known, which contains, % mass: as an antiseptic - borax 5.5…6.5, as a fire retardant - boric acid 10.5…11.5, and wood fibers - the rest [1].
Dezavantajele materialului cunoscut constau în costul lui sporit din cauza utilizării boraţilor, precum şi faptul că în procesul de aplicare uscată a materialului se formează mult praf, care conţine substanţe dăunătoare pentru sănătate, fiind imposibil de a lucra fără respirator. În plus, un astfel de amestec de aer şi praf, la depăşirea concentraţiei maxim admisibile de praf în aer, este periculos pentru sănătatea omului. The disadvantages of the known material are its high cost due to the use of borates, as well as the fact that in the process of dry application of the material a lot of dust is formed, which contains substances harmful to health, making it impossible to work without a respirator. In addition, such a mixture of air and dust, when exceeding the maximum permissible concentration of dust in the air, is dangerous to human health.
Este cunoscut un procedeu de preparare a materialului izolant, care include prelucrarea materialului din celuloză cu acid boric şi boraţi şi pulverizarea lui pe o suprafaţă de izolare [2]. A process for preparing insulating material is known, which includes processing cellulose material with boric acid and borates and spraying it onto an insulating surface [2].
Dezavantajele materialului izolant cunoscut sunt costul relativ ridicat al boraţilor, necesitatea de a preveni pătrunderea în organismul lucrătorului a prafului, apariţia căruia este inevitabilă în procesul de aplicare uscată a materialului. Totodată materialul cunoscut se desprinde şi nu prea bine rezistă la umiditate, ceea ce nu permite de a-l utiliza în încăperi umede. The disadvantages of the known insulating material are the relatively high cost of borates, the need to prevent dust from entering the worker's body, the appearance of which is inevitable in the process of dry application of the material. At the same time, the known material peels off and does not withstand moisture very well, which does not allow it to be used in damp rooms.
Este de asemenea cunoscut un material termoizolant pentru construcţie, care conţine fibre din celuloză, acid boric, boraţi şi adeziv. Materialul se pulverizează sub presiune înaltă pe o suprafaţă de izolare [3]. A thermal insulation material for construction is also known, which contains cellulose fibers, boric acid, borates and adhesive. The material is sprayed under high pressure onto an insulating surface [3].
La dezavantajele materialului izolant cunoscut se referă faptul că insuflarea uscată sau metoda de montare manuală a materialului izolant este însoţită de prăfuire cu fibre fine şi adaosuri în formă de praf, care practic este imposibil de înlăturat. The disadvantages of the known insulating material include the fact that the dry blowing or manual installation method of the insulating material is accompanied by dusting with fine fibers and dust-like additions, which is practically impossible to remove.
În plus, rezistenţa la compresiune redusă limitează utilizarea materialelor cunoscute, de exemplu, pentru instalarea podelelor «plutitoare». In addition, the low compressive strength limits the use of known materials, for example, for the installation of "floating" floors.
Problema pe care o rezolvă invenţia constă în excluderea prăfuirii, sporirea rezistenţei mecanice a materialului, sporirea adeziunii la suprafaţa care se protejează. The problem that the invention solves consists in excluding dust, increasing the mechanical resistance of the material, and increasing adhesion to the surface being protected.
Problema se soluţionează prin aceea că compoziţia termoizolantă pentru construcţie conţine fibră din celuloză, antipirenă şi antiseptic. Totodată în calitate de antipirenă şi antiseptic conţine sticlă lichidă, diluată cu apă în raport de 1:1…1:3, în următorul raport al componentelor, % mas.: The problem is solved by the fact that the thermal insulation composition for construction contains cellulose fiber, fire retardant and antiseptic. At the same time, as a fire retardant and antiseptic, it contains liquid glass, diluted with water in a ratio of 1:1…1:3, in the following ratio of components, % mass:
fibră din celuloză 70…90 sticlă lichidă 10…30.cellulose fiber 70…90 liquid glass 10…30.
Suplimentar în compoziţie poate fi introdus un component pentru sporirea rezistenţei la apă a sticlei lichide, de exemplu, metasilicat de sodiu, în cantitate de 6…7% din masa sticlei lichide până la diluarea ei cu apă. Additionally, a component can be introduced into the composition to increase the water resistance of the liquid glass, for example, sodium metasilicate, in an amount of 6...7% of the mass of the liquid glass until it is diluted with water.
Fibra din celuloză poate fi amestecată cu sticla lichidă nemijlocit la aplicarea compoziţiei pe suprafaţa de protejare. The cellulose fiber can be mixed with the liquid glass directly when applying the composition to the protective surface.
Compoziţia de asemenea poate fi executată în formă de panouri sau învelişuri termoizolante, executate la pulverizarea ei în forme demontabile şi uscare ulterioară. The composition can also be made in the form of thermal insulation panels or coatings, made by spraying it into removable forms and subsequent drying.
Rezultatul tehnic constă în îmbunătăţirea adeziunii la substrat, excluderea prăfuirii compoziţiei de construcţie, sporirea rezistenţei mecanice a materialelor pe baza compoziţiei, precum şi reducerea semnificativă a costului ei. Totodată compoziţia posedă proprietăţi sporite de rezistenţă la foc, antiseptice şi termoizolante. The technical result consists in improving adhesion to the substrate, excluding dusting of the construction composition, increasing the mechanical strength of materials based on the composition, as well as significantly reducing its cost. At the same time, the composition possesses increased fire resistance, antiseptic and heat-insulating properties.
În calitate de materie primă pentru obţinerea fibrei din celuloză poate fi utilizată maculatura, deşeurile vegetale şi lemnoase. Waste paper, vegetable and wood waste can be used as raw material for obtaining cellulose fiber.
Un avantaj al utilizării în calitate de antipirenă şi antiseptic a sticlei lichide este disponibilitatea acesteia, costul mic, rezistenţa la foc şi lipsa toxicităţii. Totodată sticla lichidă prezintă un antiseptic foarte bun, ecologic pur (previne formarea de mucegai, putregai, ciuperci), posedă proprietăţi înalte de adeziune la substraturile de natură chimică diferită, precum şi semnificativ sporeşte rezistenţa mecanică a materialelor pe baza compoziţiei. An advantage of using liquid glass as a flame retardant and antiseptic is its availability, low cost, fire resistance and lack of toxicity. At the same time, liquid glass is a very good antiseptic, ecologically pure (prevents the formation of mold, rot, fungi), has high adhesion properties to substrates of different chemical nature, and significantly increases the mechanical strength of materials based on the composition.
Fibra din celuloză poate fi amestecată cu sticla lichidă nemijlocit la aplicarea compoziţiei pe suprafaţa de izolare. Totodată compoziţia se lipeşte bine şi după uscare posedă proprietăţi înalte de termoizolare. Cellulose fiber can be mixed with liquid glass directly when applying the composition to the insulation surface. At the same time, the composition adheres well and after drying has high thermal insulation properties.
Compoziţia de asemenea poate fi pulverizată în forme demontabile, uscată, apoi utilizată în formă de panouri sau învelişuri termoizolante cu grosimea necesară. The composition can also be sprayed into removable forms, dried, then used in the form of thermal insulation panels or coatings of the required thickness.
În cazul când materialele pe baza compoziţiei sunt utilizate într-un mediu umed, în componenţa ei poate fi introdus în concentraţie efectivă metasilicat de sodiu, în cantitate de 6…7% din masa sticlei lichide (până la diluarea ei cu apă). In the case when materials based on the composition are used in a humid environment, sodium metasilicate can be introduced into its composition in an effective concentration, in an amount of 6…7% of the mass of the liquid glass (until it is diluted with water).
Exemple de preparare a compoziţiei termoizolante pentru construcţie Examples of preparation of thermal insulation composition for construction
Exemplul 1 Example 1
Maculatura se mărunţeşte într-un dispozitiv-uscător de mărunţire până la obţinerea materialului fibros cu dimensiunile particulelor de cel mult 5 mm. Masa obţinută este în formă de vată, gata pentru transportare. La locul de utilizare componentele sunt dozate în cantităţile necesare. Într-un vas pentru amestecare sticla lichidă în cantitate de 10% mas. se diluează cu apă în raport de 1:1. Fibra din celuloză în cantitate de 80% mas. cu ajutorul instalaţiei de pulverizare se aplică pe suprafaţa de izolare, concomitent dintr-un ajutaj suplimentar se injectează cu aer comprimat sticla lichidă, diluată cu apă, umezind fibra din celuloză. The waste is shredded in a shredding dryer until fibrous material with particle sizes of no more than 5 mm is obtained. The mass obtained is in the form of cotton wool, ready for transportation. At the place of use, the components are dosed in the required quantities. In a mixing vessel, liquid glass in an amount of 10% by weight is diluted with water in a ratio of 1:1. Cellulose fiber in an amount of 80% by weight is applied to the insulation surface using a spraying installation, at the same time, liquid glass diluted with water is injected with compressed air from an additional nozzle, wetting the cellulose fiber.
Exemplul 2 Example 2
Deşeurile vegetale se mărunţesc în dispersor până la obţinerea materialului fibros cu dimensiunile particulelor de cel mult 5 mm. Masa obţinută este în formă de vată, gata pentru transportare. La locul de utilizare componentele sunt dozate în cantităţile necesare. Pentru prepararea compoziţiei termoizolante pentru construcţie, utilizată într-un mediu umed, sticla lichidă în cantitate de 9,4% mas. se amestecă cu 0,6% mas. a componentului pentru sporirea rezistenţei la apă a sticlei lichide, de exemplu, metasilicat de sodiu, apoi se diluează cu apă în raport de 1:1. Fibra din celuloză se aplică pe suprafaţa de izolare cu aer comprimat, totodată la ieşirea fibrei din ajutajul instalaţiei pneumatice aceasta se umezeşte cu sticla lichidă diluată şi amestecată cu metasilicat de sodiu, respectând raportul de greutate între ele de 4:1 (fibra din celuloză la sticla lichidă pregătită). The vegetable waste is crushed in a disperser until fibrous material with particle sizes of no more than 5 mm is obtained. The mass obtained is in the form of cotton wool, ready for transportation. At the place of use, the components are dosed in the required quantities. To prepare the thermal insulation composition for construction, used in a humid environment, liquid glass in an amount of 9.4% by weight is mixed with 0.6% by weight of the component for increasing the water resistance of liquid glass, for example, sodium metasilicate, then diluted with water in a ratio of 1:1. The cellulose fiber is applied to the insulation surface with compressed air, at the same time, when the fiber exits the nozzle of the pneumatic installation, it is moistened with diluted liquid glass mixed with sodium metasilicate, observing the weight ratio of 4:1 (cellulose fiber to prepared liquid glass).
La utilizarea compoziţiei solicitate semnificativ se îmbunătăţesc indicii ei fizico-mecanici şi economici. When using the requested composition, its physical, mechanical and economic indicators are significantly improved.
