研究自制的硫磺分散体的各项性能指标,并分析对石棉胶乳密封纸板性能的影响。研究结果表明:随着硫磺分散体研磨时间延长,其粒径逐渐减小,电负性逐渐增加;在密封纸板中使用硫磺分散体比普通硫磺所得的产品具有更高的抗拉强度、更低的压缩率和更高的回弹率,证明硫磺分散体有更好的硫化效果,且随着研磨时间延长,密封纸板的抗拉强度和回弹率逐渐增加,压缩率逐渐降低,硫化效果不断提高;与硫磺分散体配合使用,丁腈胶乳作为胶黏剂所制得的密封纸板比丁苯胶乳的具有更高的抗拉强度、更低的压缩率和更高的回弹率。
The performance of self-made sulfur dispersions was studied, and the influence of asbestos latex sealing paperboard performance was analyzed. The results show that with the prolongation of grinding time, the particle size of sulfur dispersion decreases and the electronegativity increases gradually. The use of sulfur dispersion in sealing paper has higher tensile strength and lower Compression rate and higher rebound rate to prove that the sulfur dispersion has a better curing effect, and with the milling time, sealing paper tensile strength and rebound rate gradually increased, the compression rate gradually decreased, the curing effect of continuous ; With the use of sulfur dispersions, nitrile latex seal as a binder made of styrene-butadiene latex has higher tensile strength, lower compression and higher rebound rate.
