The preparation method comprises the following steps: (1) preparing organic silicon grafted polystyrene: (1.1) preparing an organic silicon grafted polystyrene component A; (1.2) preparing an organic silicon grafted polystyrene component B; (1.3) compounding; (2) mixing materials; (3) pre-foaming; (4) curing to obtain the halogen-free flame-retarding polystyrene foam. By adopting the preparation method, the problems in the prior art that the high and low temperature resisting performance of a foam material is relatively low and a flame-retarding function cannot be released better are solved; the prepared halogen-free flame-retarding polystyrene foam has the following beneficial effects that (1) the high-temperature-resisting and flame-retarding performance is excellent; (2) a halogen-free flame-retarding function is realized, and oil stain harmful substances and environment pollution substances are not generated in a combustion process; (3) the mechanical properties are excellent and the anti-impact capability is strong.

The invention discloses a mining full-length bolting-grouting agent and a preparation method thereof. A group of materials comprise, by mass, 40-50 parts of polyisocyanate, 10-20 parts of a reactive diluent, 1-3 parts of a surfactant, 10-20 parts of anhydrous calcium chloride, 20-30 parts of aggregate and 5 parts of a suspending agent; the material group B comprises the following components in parts by mass: 40-50 parts of an inorganic silicate solution, 12-22 parts of small molecular alcohol, 0.1-0.5 part of polymer rubber powder, 0.1 part of a catalyst, 2 parts of a suspending agent and 30-40 parts of aggregate; the volume ratio of the component A material to the component B material is 1: (0.5-1). The problems that an existing anchoring agent is inconvenient to use for full-length anchoring of an anchor rod or an anchor cable, the anchoring force is reduced when the anchoring agent encounters water, and diffusivity is poor are solved.
