specific Embodiment approach 1

[0018] Specific embodiment one: the black matte dipping glue of the present invention is made up of separately packaged component A and component B, and component A consists of molybdenum-modified thermosetting phenolic resin solution of 9.5%~12% by mass percentage, 2.0%~ 4.0% thermoplastic phenolic resin, 13%~16.5% nitrile rubber, 2.0%~4.0% polyvinyl acetal, 0.5%~1.5% colorant, 1.0%~2.5% matting agent, 0.1%~ Composed of 0.4% sulfur and 59.1% to 71.9% of organic solvents, the sum of the mass percentages of each component in component A is 100%; component B consists of 10% to 20% of curing agent and 80% to 90% by mass percentage % organic solvent composition, the sum of the mass percentages of each component in component B is 100%; when in use, component A and component B can be mixed uniformly at a volume ratio of 9:1; component A and component B The organic solvents used are the same.

specific Embodiment approach 2

[0019] Specific embodiment two: The difference between this embodiment and specific embodiment one is: the first component consists of 10% to 11.5% molybdenum modified thermosetting phenolic resin solution, 2.5% to 3.5% thermoplastic phenolic resin, and 13.5% by mass percentage. %~15.5% of nitrile rubber, 2.5%~3.5% of polyvinyl acetal, 0.8%~1.2% of colorant, 1.2%~2.2% of matting agent, 0.2%~0.3% of sulfur and 62.3%~69.3% % organic solvent composition, the mass percentage sum of each component in the first component is 100%. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one is: first component is by mass percentage by the molybdenum modified thermosetting phenolic resin solution of 10.5%, the thermoplastic phenolic resin of 3.0%, the nitrile rubber of 14.5%, 3.0% polyvinyl acetal, 1.0% colorant, 1.8% matting agent, 0.25% sulfur and 65.95% organic solvent. Other steps and parameters are the same as in the first embodiment.

Abstract

The invention discloses a black matt impregnated rubber and a preparation method. The invention solves the problems that the current brake sheet primer has poor high temperature stability, short preservation time and poor manufacturability, the color can not meet black matt, and the ingredients are easy to be layered. The black matt impregnated rubber is composed of single packaged ingredients ofA and B; the A ingredient consists of a molybdenum modified thermosetting phenolic resin solution, thermoplastic phenolic resin, butadiene-acrylonitrile rubber, polyvinyl acetal, coloring agent, delustering agent, sulphur and organic solvent; the B ingredient consists of a curing agent and organic solvent. The method of the invention comprises the following steps: 1, the butadiene-acrylonitrile rubber and the polyvinyl acetal are respectively dissolved in the organic solvent, then the mixture is evenly mixed with the molybdenum modified thermosetting phenolic resin solution, the thermoplasticphenolic resin, the coloring agent and the delustering agent to prepare the ingredient A; 2, the curing agent is dissolved in the organic solvent to obtain the ingredient B. The black matt impregnated rubber has good high-temperature stability, long preservation time, good manufacturability and even ingredients.

Description

technical field [0001] The invention relates to a preparation method for dipping. Background technique [0002] Brake pad primer is an adhesive product used in the automotive industry. It is mainly used for impregnation of various friction pads such as automobile drum brake pads, train synthetic brake shoes, tractor clutch plates, steering grinding pads, and motorcycle drum brake pads. And impregnation of various mechanical equipment brakes. However, the normal temperature storage period of the brake pad primer used at present is 4 months, and when stored for 3 months in the summer with higher temperature, there will be a gel phenomenon, which seriously affects the promotion and application of its market; Short time, poor process performance and appearance color cannot meet the requirements of black and matt. The current preparation method of primer has the defects of uneven dissolution of components and easy layering of components. Contents of the invention [0003] ...
