Abstract
A film material with high specific weight for effectively reducing noise contains PVC (5-35 wt.%), tungsten powder (40-90), coupling agent (1-10) and assistant (4-15). Its advantages are high mechanical performance and specific weight, high fire-retarding nature and machinability and no poison.
Description
Technical field
What the present invention relates to is a kind of matrix material, and particularly a kind of high specific gravity film composite material belongs to polymeric material field.
Background technology
In Composite Preparation, the density of filler itself and the ratio that can insert all play a decisive role to the density that improves the gained matrix material.Find by literature search, China Patent No. is: 97197487.X, patent name is: high density composite, announced a kind of high density composite, this patent the tungsten powder combination of 2～40 microns of the fiber that improves intensity and diameters, is made a kind of material (as projectile core equivalent material nontoxic, unleaded, environmentally safe, that save money) that can be used as plumbous substitute by binding agent.Its material composition is tungsten powder and fiber and caking agent, by injection moulding, compression molding, is used to be sought after the occasion that plumbous high-density does not wish to have Lead contamination again, and as the substitute of leaded high density material.But this material since its composition (fiber and caking agent) only determined can be with injection moulding or compression molding, so difficulty is made large-area film.
Summary of the invention
The present invention is directed to disadvantages of background technology and defective, provide a kind of and designed, produce, the simple high specific gravity thin-film material of technology according to Principles of Acoustics.The present invention is achieved by the following technical solutions, and each component of the present invention and weight percent thereof are specific as follows: PVC:5%～35%; Particle diameter is less than 2 microns tungsten powder: 40%～90%; Coupling agent: 1%～10%; Auxiliary agent: 4%～15%; By can particularly making large-area film through injection moulding or compression molding after mixing by calendering formation technology.
Wherein the diameter of tungsten powder is preferably 0.1～1.8 micron, and coupling agent adopts one or more in the titante coupling agent, one or more in the common stablizer of selection of auxiliary, softening agent and the antiaging agent.
The present invention has substantive distinguishing features and marked improvement.Material of the present invention not only has very high density, and has good mechanical mechanics property, and is nontoxic, fire-retardant, particularly abandoned fiber and caking agent in material composition, therefore can make flexible film by rolling continuously shaped technology.This material can be used for the sound insulation and noise reducing of noise.
