實(shí)際上大家都知道的，電纜橋架的防火措施十分重要，以下就是濟(jì)南橋架廠家講下組合式橋架選擇防火材料的方法介紹的相關(guān)內(nèi)容。

In fact, we all know that the fire prevention measures of cable tray are very important. The following is the introduction of the method of selecting fire prevention materials for combined cable tray by the cable tray manufacturer in Jinan.

組合式橋架防火涂料是在飾面型防火涂料基礎(chǔ)上結(jié)合自身要求發(fā)展起來的，因而原料的研究及選用可參考飾面型防火涂料。玻璃鋼電纜橋架防火涂料作為特種涂料，除了應(yīng)具有普通涂料的裝飾作用和對電纜基材提供物理保護(hù)外，還需要具有阻燃耐火的特殊功能，這就要求他們能夠在火災(zāi)形成一定的溫度發(fā)泡保溫層。

The composite bridge fireproof coating is developed on the basis of the decorative fireproof coating and in combination with its own requirements, so the research and selection of raw materials can refer to the decorative fireproof coating. As a special coating, the fire retardant coating for glass fiber reinforced plastic cable tray should not only have the decorative effect of ordinary coating and provide physical protection for cable substrate, but also have the special function of flame retardant and fire-resistant, which requires them to be able to form a certain temperature foam insulation layer in a fire.

因此，存在其基部的特殊要求，要求基料能與整個(gè)涂料體系協(xié)和，該涂層既具有良好的機(jī)械物理和化學(xué)性能，又能在受火時(shí)形成較好的泡沫隔熱層，為了達(dá)到一定的時(shí)間阻燃劑，在發(fā)泡層需要較高的溫度不關(guān)閉。

Therefore, there are special requirements for its base. The base material is required to be compatible with the entire coating system. The coating has good mechanical, physical and chemical properties, and can form a good foam insulation layer when exposed to fire. In order to achieve a certain time of flame retardant, the foam layer needs to be kept open at a higher temperature.

另外組合式橋架電纜橡膠類材料是高彈性體，和電纜需要進(jìn)行定期維護(hù)移動，這就要求涂層應(yīng)具有足夠的耐伸縮變化的性能，還要求防火涂料對橡膠電纜類材料無腐蝕性能、附著力好，良好的室溫固化，裝飾涂料好。一個(gè)關(guān)鍵的決定了這些要求的選擇是為了解決具有良好的對基材的附著力和其他問題的涂料。

In addition, the rubber materials of the combined bridge cable are highly elastic, and the cable needs to be regularly maintained and moved. This requires that the coating should have sufficient resistance to expansion and contraction changes. It also requires that the fire retardant coating has no corrosion performance, good adhesion to rubber cable materials, good room temperature curing, and good decorative coating. A key decision in the selection of these requirements is to solve the coating with good adhesion to the substrate and other problems.

樹脂基體材料的選擇被修改，使其適應(yīng)各種阻燃添加劑，該這兩種理想的防火隔熱，又能適應(yīng)電線電纜地下溝應(yīng)用的環(huán)境條件。在電纜防火涂料的研究，不僅防火涂料樹脂的選擇有很好的防火效果，從應(yīng)用的角度需要，要求防火涂料具有耐水性，耐酸性，堿性，霉性和耐腐蝕性和電纜具有用于電纜凝聚力強(qiáng)堿。

The selection of resin matrix materials has been modified to adapt to various flame retardant additives. These two ideal fire and heat insulation can also adapt to the environmental conditions of wire and cable trench application. In the research of cable fire-retardant coating, not only the selection of fire-retardant coating resin has a good fire-retardant effect, but also from the application point of view, the fire-retardant coating is required to have water resistance, acid resistance, alkali resistance, mildew resistance and corrosion resistance, and the cable is required to have strong alkali for cable cohesion.

組合式橋架防火涂料的基料一般選用氯化橡膠、全氯乙烯，氨基樹脂，酚醛樹脂，丙烯酸類樹脂，溶劑基醇酸樹脂和丙烯酸樹脂乳液，雙面氯乙烯乳液，白膠，丙烯酸類乳液及其它水溶性樹脂。能用于制備電纜防火涂料的樹脂有很多，在實(shí)踐中兩種或更多種樹脂的混合物經(jīng)常使用，相互之間取長補(bǔ)短，以獲得所需的涂膜性能。

The base materials of the composite bridge fireproof coating are generally chlorinated rubber, perchloroethylene, amino resin, phenolic resin, acrylic resin, solvent alkyd resin and acrylic resin lotion, double-sided vinyl chloride lotion, white glue, acrylic lotion and other water-soluble resins. There are many resins that can be used to prepare fire retardant coatings for cables. In practice, mixtures of two or more resins are often used to learn from each other to achieve the required film performance.
