Abstract
The invention provides a method for producing a triangular belt by adopting water emulsion slurry leaching cloth, which comprises the following steps: preparing raw auxiliary materials, preprocessing water emulsion slurry, gumming a canvas, wrapping the triangular belt and vulcanizing the triangular belt. The method can solve the technical problem that the water emulsion slurry is replaced by gasoline emulsion slurry in the cloth leaching process, eliminates the potential safety hazards and the volatilization of harmful gas during the production and greatly reduces the production cost, thereby ensuring that the comprehensive quality performance of the triangular belt is stably improved.
Description
Technical field
The present invention relates to a kind of processing method of vee belt, particularly adopt the water and milk rubber cement to soak the method for cloth production vee belt.
Background technique
China produces the enterprise of classical V-belt at present; The canvas rubberizing has 2/3 to adopt gum dipping process approximately, and rubber cement all uses the gasoline rubber cement, and the gasoline rubber cement (is prone to breaking out of fire) in preparation and immersing glue process potential safety hazard is outstanding; The harmful gas volatilization is more serious, befouling environment; And because International Crude Oil constantly soaring in recent years, the price of the main body industrial naptha of gasoline rubber cement is also high synchronously always, causes V band cost of production to improve constantly; Because the canvas that soaks of gasoline rubber cement receives ambient temperature, humidity effect bigger before use, the technology capability quality is unstable, thereby directly has influence on the combination property quality of finished product V band.
Summary of the invention
The objective of the invention is to overcome above deficiency, a kind of method that adopts the water and milk rubber cement to soak cloth production vee belt is provided.Can solve the alternative gasoline rubber cement of water latex slurry and soak cloth process engineering problem; The potential safety hazard in the elimination production process and the volatilization of harmful gas; Reduce production costs significantly; Simultaneously, make the other problem that exists in the background technique also be able to solve, thereby guaranteed the stable raising of V band comprehensive quality performance.
