Abstract

可以防止磁场干扰的容器及其材料,是由塑料或其它材料作底基,在其表面喷涂一层软磁材料,再喷复一层装饰材料而成,外表面配有美观的图案,适合于保存录音带,录像带,计算机所用的磁盘等需防磁的物品,其材料还可以做成地板,墙布用于计算机机房等。
若将铁粉涂复于底基(纸、塑料等)所做成的材料还可兼有防静电的作用。

Description

现有的磁制物品如录音带、录像带、计算机用的磁盘等,大都自然存放或放入塑料制作的盒子中,这如同置于空间磁场,易于受到空间磁场的污染,其结果是使被保存的信号时间久了会发生崎变,例如录音带音质变差声音变轻;录像带图像模糊;计算机磁盘记录的信息紊乱数据丢失等。
申请人曾设计了“高保真磁带盒”(专利号:ZL86204943,和“高保真录像带盒”(专利公开号:GK87104949,本发明是以上发明的扩展。
本发明的目地是给磁制物品提供一种磁屏蔽材料,并根据不同的磁制物品形状制成各种不同形状的磁屏蔽容器。
本发明的磁屏蔽材料是由一般材料如塑料或纸等涂复软磁材料而成,软磁材料可以用铁氧体也可以是软磁材料混合其它材料如塑料之后成型而成,在其表可再喷复一层具有保护作用的美化装饰层。
例如用塑料制作的盒子,在其外表面或内表面喷涂一层锰锌铁氧体后,将盒子放置于磁场中,则盒内的磁场强度将减弱到只有原来的三千分之一。
如果喷涂的材料是铁或铁的合金粉末,还可兼有静电屏蔽的作用。
喷复美化装饰层的作用是保护软磁材料层不使之脱落,另有外观美化的作用。
这种磁屏蔽材料有广范的用途,可根据需要做成各种不同的形状,如存放多个磁带的磁带盒[图(1)],录音带带仓盒[图(2)],扁方形磁带外盒[图(2)],计算机用的磁盘盒[图(4)],和需要防磁的仪表外盒[图(5)]等。
在图(6)中1为底基材料层2为软磁材料层,3为装饰涂料层。
将上述材料也可以做成局部需要防磁的防护层,例如用上述材料将录音机的盒带仓围护起来以屏蔽喇叭磁场和机内的杂散磁场。
用软磁材料喷涂于塑料板,墙布上等,在表面美化后可用于计算机机房等墙的内壁和地板,来屏蔽外界磁场,电场等的污染。

Claims (1)

  1. 一种可以防止磁场干拢的磁屏蔽材料及用这种材料制作的可以存放录音带、录像带、计算机磁盘等需要防磁物品的容器,其特征在于:
    a、磁屏蔽材料是由塑料或纸等底基面上粘附有软磁材料而成。
    b、磁屏蔽材料也可以是由塑料或其它材料掺有软磁材料而成。
    c、用上述a或b所述的材料制作的容器等,在其内或外表面可再粘附有一层护性美化装饰层。
