Basalt fiber base composite geotextile and preparation method thereof
The invention discloses basalt fiber base composite geotechnical cloth and a preparation method thereof, and the basalt fiber base composite geotechnical cloth comprises a functional protective film layer, a modified high polymer layer and a basalt fiber gridding cloth layer, the modified high polymer layer comprises the following raw materials in parts by weight: 45-55 parts of matrix asphalt, 15-25 parts of phenolic resin, 8-14 parts of butadiene styrene rubber powder, 4-8 parts of a curing agent, 3-7 parts of an ethylene-vinyl acetate copolymer and 4-12 parts of a modified material. The composite geotextile which is high in tensile strength, resistant to high temperature, good in cohesiveness and excellent in low-temperature toughness is produced by adopting scientific and reasonable design and formula, can be firmly bonded with a base layer in actual use, has a good stress absorption effect, and effectively prevents expansion of reflection cracks of a pavement; the basalt fiber gridding cloth is used, the good interlocking effect on the modified high polymer is achieved, the raw material consumption is greatly reduced while the performance is met, and the great cost advantage and market performance are achieved.
本发明公开了一种玄武岩纤维胎基复合土工布及其制备方法，包括功能防护膜层，改性高聚合物层和玄武岩纤维网格布层，所述改性高聚合物层包括以下重量份数原料：基质沥青45～55份、酚醛树脂15～25份、丁苯橡胶粉8～14份、变定剂4～8份、乙烯‑醋酸乙烯共聚物3～7份、改性料4～12份。本发明采用科学合理的设计和配方生产出抗拉强度高、耐高温、粘结性好和低温韧性较优的复合土工布，在实际使用中能够与基层粘结牢固，具有良好的应力吸收作用，有效防止路面反射裂缝的扩展；本发明使用玄武岩纤维网格布，对改性高聚合物有很好的嵌锁作用，满足性能的同时大量降低原材料消耗，具有极大的成本优势和市场性。
