专利汇可以提供Flexible ionizing radiation shield barriers专利检索，专利查询，专利分析的服务。并且Flexible ionizing radiation shield barriers which comprise a heavily lead-loaded elastomeric layer adhering to a fabric base, thereby forming a thick heavy flexible material useful in shielding against radiation. The lead loading comprises at least 55 percent by total weight of the material, and is comprised of lead particles of, at most, 200 mesh.，下面是Flexible ionizing radiation shield barriers专利的具体信息内容。

权利要求

2. The material of claim 1 wherein the fabric base constitutes from 2 to 10 percent by weight, the elastomer constitutes from 3 to 15 percent by weight, and the lead constitutes from 55 to 95 percent by weight, all based on the total weight of the barrier.

3. The material of claim 1 wherein an intermediate adhesive layer is present between said fabric and said elastomer.

4. The material of claim 3 wherein the elastomer of said lead-loaded elastomer is a synthetic vinyl polymer.

5. The material of claim 4 wherein said elastomer is formed from 2-chloro-butadiene-1,3.

6. The material of claim 4 wherein said lead-loaded elastomeric layer comprises from about 0.5 to about 20 percent by weight of a lead powder dispersing agent, based on the weight of said elastomer alone.

7. The barrier of claim 6 wherein the total thickness of the lead-loaded elastomeric layer is from 0.2 to 0.5 inches.

8. The barrier of claim 7 wherein the elastomer is formed from 2-chloro-butadiene-1,3.

9. The barrier of claim 8 wherein the fabric is an asbestos-base fabric and the adhesive layer comprises a first elastomeric layer formed from 2-chloro-butadiene-1,3 adhering to said fabric and a butyl rubber layer adhering to said first elastomeric layer and said lead-loaded elastomer.
