橡塑保温材料是以橡胶和聚氯乙烯（NBR/PVC）为主要材料，经混炼、密炼、连续挤出、加热发泡、冷却切割而成的混合发泡材料。橡塑保温材料有一个特殊的地方，就是它的结构不同于其他保温材料，属于闭孔结构：由许多闭孔小气泡组成。气泡的大小和密度与发泡技术密切相关。那么橡塑保温材料闭孔结构的作用是什么？

Rubber plastic thermal insulation material is a mixed foaming material made of high-quality rubber and polyvinyl chloride (nbr/pvc) as main materials through mixing, internal mixing, continuous extrusion, heating foaming, cooling and cutting. Rubber and plastic insulation materials have a special place, that is, its structure is different from other insulation materials, belonging to closed cell structure: it is composed of many closed cell small bubbles. The size and density of bubbles are closely related to foaming technology. So what is the function of closed cell structure of rubber and plastic insulation materials?

华美橡塑采用精确控制微孔泡沫技术，大大提高了电芯的闭孔率，使橡塑保温材料具有弹性特性，压制柔软，弹性好。可以在一些特殊的场合使用，比如一些特殊的车间或者运动场馆，因为在这些地方使用很容易对人体造成伤害。加装橡塑保温材料可起到缓冲和防震的作用，能有效保护身体不受伤害。

Huamei rubber and plastic adopts the precise control microporous foam technology, which greatly improves the cell closing rate of the cell and makes the rubber and plastic insulation material have elastic properties, soft pressing and good elasticity. It can be used in some special occasions, such as some special workshops or sports venues, because it is easy to cause harm to human body. Adding rubber and plastic insulation materials can play a role in cushioning and shockproof, and can effectively protect the body from injury.

橡塑是高品质的保温材料，是隔冷、隔热防结露的克星，热传导系数低并且保持稳定，对任何热介质起隔绝效果。橡塑材料符合标准GB8624《建筑材料燃烧性能分析法》经测试判定为GB8624B1级难燃性材料。橡塑为闭泡式结构，外界空气中的水很难渗透到材料之中，具有优异的抗水汽渗透能力，保冷保温层外表不必再添加隔汽层。

Rubber and plastic is a high-quality heat preservation and energy-saving material. It is the bane of cold insulation, heat insulation and anti condensation. Its thermal conductivity is low and stable, and it has the effect of isolating any thermal medium. The rubber and plastic materials comply with the national standard GB8624 "analysis method for burning performance of building materials" and are determined to be gb8624b1 class flame retardant materials after testing. The rubber and plastic are of closed bubble structure. It is difficult for the water in the outside air to penetrate into the material. It has excellent water vapor permeability resistance. There is no need to add a vapor barrier on the surface of the cold insulation layer.

其次，闭孔结构使橡塑保温材料的导热系数更低。由于物料内部分布着许多封闭的小气泡，可以阻止热能散发，同时阻止冷气流进入物料，从而形成稳定恒定的空气温度。材料的导热系数较低，保温效果较好。

Secondly, the closed cell structure makes the thermal conductivity of rubber and plastic insulation materials lower. Because there are many closed small bubbles in the material, it can prevent the heat energy from emitting and the cold air from entering the material, so as to form a stable and constant air temperature. The thermal conductivity of the material is low and the thermal insulation effect is good.

闭孔结构使华美橡塑保温材料具有很强的抗穿透性。由于材料中分布着具有细密闭孔结构的小气泡，形成独立的封闭结构，外界的水汽不易进入材料，从而提高了穿透力，无需加隔汽层，由于材料稳定，即使局部划伤，也不会影响整体的水汽阻隔性，延长橡塑保温材料的使用寿命。

The closed cell structure makes Huamei rubber and plastic insulation materials have strong penetration resistance. As small bubbles with fine closed cell structure are distributed in the material to form an independent closed structure, the external water vapor is not easy to enter the material, so the penetration is improved. There is no need to add a vapor barrier. Because the material is stable, even if it is scratched locally, it will not affect the overall water vapor barrier and prolong the service life of rubber and plastic insulation materials.
