Embodiment Construction

[0015] A reticular polyurethane foam explosion-proof barrier material compounded with activated ultrafine waste rubber powder is prepared from the following raw materials in parts by weight: 80 parts of polyether polyol with a molecular weight of 3000, 60 parts of toluene diisocyanate, activated ultrafine waste 5 parts of rubber powder, 8 parts of foaming agent, 0.5 part of foam stabilizer, 0.1 part of stannous octoate, 0.1 part of triethylenediamine, 1 part of nano-expanded graphite, and 1 part of ultrafine rare earth tailings powder.

[0016] Among them, the activated superfine waste rubber powder is obtained by putting 150 mesh superfine waste rubber powder into the activation solution at 40°C for 2.5 hours, then filtering, washing and drying; the activation solution is made of 30% hydrogen peroxide and high iron Potassium acid and water are compounded according to the weight part of 0.1:0.1:1.

[0017] The preparation method of the reticulated polyurethane foam explosion-p...

Abstract

The invention discloses a mesh-shaped polyurethane foam anti-explosive barrier material mixed with activated superfine waste rubber powder and its preparation method. In the invention, a traditional mesh-shaped polyurethane foam material is added with superfine waste rubber powder after activation treatment of hydrogen peroxide / potassium ferrate composite system so as to perform filling and modification treatment. The surface of the activated waste rubber powder contains multiple functional groups, the reaction activity is high, and the compatibility with the system is good; the material has the advantages of reducing the production cost of the mesh-shaped polyurethane foam, effectively improving the physical performance and wave absorbing oil resistance of the mesh-shaped polyurethane foam, prolonging the service life and further improving the anti-explosive barrier ability; besides, the added nano expanded graphite and superfine rare-earth tailing powder and other materials have coordinately enhanced the meshing performance of the composite polyurethane material; the aperture ratio is higher, and the anti-explosive barrier ability is stronger.

Description

technical field [0001] The invention relates to the technical field of explosion-proof barrier materials, in particular to a reticular polyurethane foam explosion-proof barrier material compounded with activated superfine waste rubber powder and a preparation method thereof. Background technique [0002] my country is a big country in tire production and automobiles. With the rapid increase of family car ownership, a large number of waste tires are produced every year. How to effectively recycle these waste tires and prevent environmental pollution has very important practical significance and huge economic value. . At present, the more common waste tire recycling methods mainly include direct utilization of prototypes, heat generation by incineration, retreading of old tires, production of recycled rubber, and production of vulcanized rubber powder. Among them, the production of rubber powder is the most common processing method. At present, it is mainly used in the fields ...
