在过去的20年中，我国电缆桥架行业在大量的技术引进、消化吸收以及自主研发的基础上，已经形成巨大的生产能力，与之配套的电缆材料、电缆设备制造业也初步形成了较完整的配套体系。这主要表现在以下方面:大型企业在市场竞争力方面具有明显的优势，赢利能力较强；中小型企业 资产营运能力较好；民营企业市场化运作机制灵活，发展迅速，沿海经济发达地区的电缆桥架制造企业优势明显。
In the past 20 years, China's cable bridge industry on a large number of technology introduction, digestion, absorption, and on the basis of independent research and development, has formed enormous production capacity, and form a complete set of cable materials, cable equipment manufacturing has initially formed a complete system of form a complete set. This is mainly manifested in the following aspects: large enterprises has obvious advantage in market competition, the profit ability is stronger; Small and medium-sized enterprise assets operation ability is good; Private enterprise flexible market operation mechanism, development is rapid, cable tray manufacturing enterprises in the coastal developed areas.

钢制电缆桥架防火涂料是在饰面型防火涂料基础上结合自身要求发展起来的，因而原料的研究及选用可参考饰面型防火涂料。钢制电缆桥架防火涂料作为特种涂料，除了应具有普通涂料的装饰作用和对电缆基材提供物理保护外，还需要具有阻燃耐火的特殊功能，这就要求它们在一定温度下能发泡形成防火隔热层。因此对其基料有一个特殊要求，要求基料能与整个涂料体系协和，使涂料既有良好的机械理化性能，又能在受火时形成较好的泡沫隔热层，为了达到一定的阻燃耐火时间，要求发泡层在高温下也不脱落。
Fire retardant coating steel cable bridge is based on the facing type fire-retardant coating with its requirements, and raw material research and choose veneer type fire-retardant coating for reference. As special coatings, fire retardant coating of steel cable bridge in addition to should have regular paint of the cable to adornment effect and base material providing physical protection, also need to have flame retardant fire-resistant special function, which requires them to a certain temperature can form fire foam thermal insulation layer. So have a special request for the basic material, require Concorde anti-rusty coating with the whole system, and improves the performance of the coating has good mechanical physics and chemistry, but also in good foam thermal insulation layer are formed when the fire, in order to achieve a certain amount of flame retardant fire-resistant time, require foam layer under high temperature does not fall off.
另外钢制电缆桥架电缆橡胶类材料是高弹性体，并且电缆需要经常检修移动，这就要求涂层应具有足够的耐伸缩变化的性能，还要求防火涂料对橡胶电缆类材料无腐蚀性能、附着力好、室温固化性好、涂膜装饰性好。上述这些要求决定了选择的关键之一是解决涂料与基材有良好的黏结性等问题。另外，对所选用的树脂基料进行改性，使其配入各种阻燃添加剂后，既有理想的防火隔热性，又能适应电线电缆地下沟应用的环境条件。在电缆防火涂料的研究中，所选用的树脂不仅使防火涂料有很好的防火效果，还需要从应用的角度出发，要求防火涂料具有抗水性、抗酸性、碱性、防霉性和电缆防腐蚀性及对电缆基材有较强的黏结性。
The other steel cable tray cable rubber materials are high elastomer, and cable need maintenance often mobile, which requires the coating should have enough scale changes of the resistance, also requirement for rubber cable fire retardant coating materials without good corrosion resistance, good adhesion, room temperature curing, coating, adornment sex is good. These requirements determine the choice of one of the key is to solve the coating and substrate with good bondability, etc. In addition, the selection of resin binders were modified, after the match into various kinds of flame retardant additives, both ideal insulating fire stays, and can adapt to the electric wire electric cable underground ditch application of environmental conditions. In the study of cable fire retardant paint, chooses the resin not only make the fire-retardant coating has good fire prevention effect, need from the perspective of application, fire-retardant coating with water resistance, resistance to acid, alkali, mouldproof and cable anticorrosive and bondability of cable base material has strong.

防火涂料的基料一般选用氯化橡胶、过氯乙烯、氨基树脂、酚醛树脂、丙烯酸树脂、醇酸树脂等溶剂型树脂和丙烯酸乳液、氯乙烯一偏二氯乙烯乳液、乳白胶、苯丙乳液等水溶型树脂。能用于制备电缆防火涂料的树脂有很多，在实际中经常采用两种以上的树脂混合使用，相互之间取长补短，以获得理想的涂膜性能。
Basic material of fire retardant coating of steel cable bridge in shandong generally selected chlorinated rubber, chlorinated polyvinyl chloride, amino resin, phenolic resin, acrylic resin, alkyd resin, solvent resin and acrylic acid emulsion, vinyl chloride flops dichloroethylene emulsion, milky white glue, styrene acrylic emulsion water soluble resin. Of fire retardant coating can be used for the preparation of cable resin has a lot of, in practice, often using a mixture of two or more of the resin, mutual complement each other, in order to obtain the ideal coating performance.
