Abstract

The invention provides a special rubber powder for high-viscosity and high-strength polyethylene polypropylene, which comprises 6-10 parts of polyethylene oxide, 2-5 parts of polyacrylamide, 20-40 parts of carboxymethyl cellulose, modified 15~30 parts of starch, 13~25 parts of instant polyvinyl alcohol, 17~32 parts of calcium formate and 3~10 parts of metakaolin are mixed. The invention has better apparent viscosity and wire drawing effect, and has higher cement strength and anti-seepage pressure after being mixed with cement. The high water absorption of high molecular polymer can effectively solve the problem of cement maintenance, and can effectively improve the cement's early rise. Strength and ultimate strength, the rubber powder has low production cost, simple preparation process and convenient use.

Description

technical field [0001] The invention relates to the field of material manufacturing, in particular to a special rubber powder for high-viscosity and high-strength polyethylene polypropylene fiber and its preparation and use method. Background technique [0002] As we all know, with the development of society, people's requirements for the environment are getting higher and higher, and the awareness of green environmental protection is becoming more and more popular. The formaldehyde content in the traditional construction glue obviously exceeds the standard, and the transportation is extremely inconvenient. Generally, the special rubber powder for polyethylene polypropylene fiber has good apparent viscosity, low cement strength, and poor actual bonding effect, or the actual bonding effect is good, but the apparent viscosity and drawing effect are not good, and there are special rubber powder for polyethylene polypropylene fiber Although the effect is good, the cost is high....
