Изобретение относитс  к строительству и может быть использовано при нанесении теплоизол ции на металлические трубы.The invention relates to the construction and can be used when applying heat insulation to metal pipes.

Цель изобретени  - повышение изо- л ционных свойств пенопластовой изол ции и снижение расхода материала путем создани  на металлической трубе многослойной теплоизол ции, каждый слой которой отличаетс  от других слоев кажущейс  плотностью и толщиной.The purpose of the invention is to increase the insulation properties of foam insulation and reduce material consumption by creating multilayer heat insulation on a metal pipe, each layer of which differs from other layers in apparent density and thickness.

На фиг. 1 и 2 показаны варианты вьшолнени  теплоизол ции на металлической трубе.FIG. Figures 1 and 2 show the options for performing thermal insulation on a metal pipe.

Согласно первому варианту (фиг. 1) металлическа  труба 1 имеет внутренний слой 2 жесткой полиуретановой пе- ноизол ции низкой плотности (0,032- 0,096 г/см) и наружный слой 3 жесткой полиуретановой пеноизол ции, имеющий плотность по крайней мере на 25% вьше, чем у сло  2, и толщи- ну, составл ющую 5-30% общей толщины слоев 2 и 3.According to the first embodiment (Fig. 1), the metal pipe 1 has an inner layer 2 of rigid low density polyurethane foam insulation (0.032-0.096 g / cm) and an outer layer 3 of rigid polyurethane foam insulation having a density of at least 25% higher, layer 2, and a thickness of 5-30% of the total thickness of layers 2 and 3.

Согласно второму варианту (фиг. 2 труба 1 имеет внутренний слой, состо щий из нескольких слоев, имеющих разную плотность, при этом слой, примыкающий к трубе, должен иметь самую низкую плотность.According to the second variant (Fig. 2, pipe 1 has an inner layer consisting of several layers having different density, while the layer adjacent to the pipe must have the lowest density.

Способ осуществл ют следующим образом.The method is carried out as follows.

Трубу 1 нагревают дл  устранени  конденсации влаги, очищают от гр зи, окалины и ржавчины (любым известным способом). Нанос т первый слой 2 вспенивающей композиции обычно в виде брызг при вращении и поступательном перемещении трубы мимо раз- брызгивающих композицию сопел, при этом труба перед нанесением композиции может быть загрунтована или покрыта антикоррозионным составом.Pipe 1 is heated to eliminate condensation, cleaned from dirt, scale and rust (by any known method). The first layer 2 of the foaming composition is usually applied in the form of splashes during rotation and translational movement of the pipe past the nozzles spraying the composition, and the pipe can be primed or coated with an anti-corrosion composition before applying the composition.

Дл  создани  на трубе слоев теплоизол ции может быть Использован любой рецепт способной вспениватьс  жидкой полиуретановой пластической композиции в зависимости от требуемых в конечном изделии конкретных характеристик. Предпочтительной  вл етс  жидка  смесь компонентов, включающих в себ  пенообразователь..To create layers of thermal insulation on the pipe, any recipe for a foaming liquid polyurethane plastic composition can be used, depending on the specific characteristics required in the final product. A liquid mixture of components comprising a foaming agent is preferred.

На первый слой пеноизол ции нанос т второй слой 3 вспенивающейс  жидкой пластической композиции, который может быть нанесен на первыйA second layer 3 of foaming liquid plastic composition is applied to the first layer of foam insulation, which can be applied to the first layer.

Толщина первого сло  пены может измен тьс  в диапазоне 2,5-15 см в зависимости от диаметра трубы, температуры, при которой должна работать труба, кажущейс  плотности пены.The thickness of the first foam layer can vary in the range of 2.5-15 cm, depending on the diameter of the pipe, the temperature at which the pipe should work, the apparent density of the foam.

Дл  получени  жесткой пены может быть использован следующий состав, мае.ч:To obtain a rigid foam, the following composition can be used, mac.h:

Дилаурат дибутиловый 0,1 Трихлормонофторметан 35 Трис-(2-хлорэтил)-фосфат 10 Все компоненты, кроме диизоциана- та, предварительно смешивают, а последний добавл ют непосредственно перед вспениванием и набрызгом на трубу. Уменьшение в составе относительного количества порообразовател  трихлормонофторметана приводит к повышению плотности.Dilaurate dibutyl 0.1 Trichloromonfluoromethane 35 Tris- (2-chloroethyl) -phosphate 10 All components, except diisocyanate, are premixed, and the latter is added just before foaming and spraying on the pipe. The decrease in the composition of the relative amount of the trichloromethane fluoride blowing agent leads to an increase in the density.

Поверх наружного сло  пеноизол ции могут быть нанесены любые слои или покрыти . Наружный слой пеноизол ции , например-,- может быть снабжен путем обертывани  или экструзии защитным или влагозадерживающимAny layer or coating may be applied over the outer layer of foam insulation. The outer layer of foam insulation, for example, -, - can be provided by wrapping or extruding with a protective or moisture retaining layer.

Благодар  высокому сопротивлению разламьшанию и высокой стойкости к абразивному износу, обеспечиваемому наружным слоем пеноизол ции, дополнительный защитный слой в большинстве случаев нужен только дл  защиты от проколов и проникновени  влаги.Due to the high resistance to cracking and high resistance to abrasive wear provided by the outer layer of foam insulation, an additional protective layer in most cases is needed only to protect against punctures and moisture penetration.
