Problems solved by technology

[0004] Although the road-use lignin fiber disclosed in this patent has a long storage period, the road-use lignin fiber has a single composition, has no flame-retardant and antistatic properties, and has a single function. Therefore, a road-use lignin fiber has been designed and its production method is necessary

Embodiment Construction

[0057] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0058] The lignin fiber used in this road is composed of the following raw materials in weight percentage: 50-70% of lignin fiber, 6-8% of leavening agent, 12-16% of mildew inhibitor, 1-4% of antistatic agent and flame retardant 18-26%; in this example, 54% lignin fiber, 7% leavening agent, 14% anti-mildew agent, 3% antistatic agent and 22% flame retardant

[0059] Using this ingredient, by using lignin fiber as the main component, and adding an appropriate amount of leavening agent, anti-fungal agent, anti-static agent and flame retardant, etc., it can make it have the characteristics of mildew resistance, flame retardancy and anti-static. Functional.

[0060] The leavening agent is a carbonate material; in this embodime...

Abstract

The invention provides a lignin fiber for roads and a method for preparing the lignin fiber. By the aid of the lignin fiber and the method, the technical problems of single components, deficiency of flame-retardant and antistatic characteristics, single functions and the like of existing lignin fibers for roads can be solved. The lignin fiber for the roads comprises, by weight, 50-70% of lignin fibers, 6-8% of swelling agents, 12-16% of mould inhibitors, 1-4% of antistatic agents and 18-26% of flame retardants. The lignin fiber and the method have the advantage of high functionality.

Description

technical field [0001] The invention relates to a road-use lignin fiber and a preparation method thereof. Background technique [0002] Lignocellulose is a kind of organic fiber, which is mainly used in road paving and is an indispensable stabilizer. The lignin fibers are flocculent or granular. The preparation method of road wood fiber is accompanied by the promotion and popularization of SMA pavement structure. It is called asphalt horseshoe macadam mixture. Crushed stone and asphalt horseshoe grease (composed of asphalt, fiber stabilizer, mineral powder, and fine aggregate) are mixed at high temperature and used as a hot-mix asphalt mixture for pavement wear layer or overlay. It has effective interlocking between aggregates , thick asphalt film, small porosity, rough surface, fiber reinforcement and other characteristics. [0003] After searching, for example, Chinese patent literature discloses a granular road lignin fiber and its preparation method [application numbe...
