Preparation method of waterproof paint
A waterproof coating and raw material technology, applied in the direction of grain processing, etc., can solve the problems of poor grinding effect, inability to break raw material particles, and difficulty in entering materials, so as to solve the problems of grinding effect and guide speed, and solve the problem of guide. The material speed is not both, the effect of improving the grinding effect

Problems solved by technology
[0003] The following problems often exist in the process of making waterproof coatings. First, because the particle size of the waterproof coating raw materials is not the same, in the process of crushing the waterproof coating raw materials, the raw materials with small particles form a buffer for the raw materials that need to be crushed. Different sizes The raw material particles need to be crushed effectively in different ways; 2. In the process of finely grinding the raw material particles, if the gap between the grinding materials is too large, the grinding effect will not be good, and the raw material particles cannot be crushed to the desired size. Size, if the material gap between the grinding is too small, it will make it difficult for the material to enter, thus affecting the crushing efficiency

Embodiment Construction
[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0030] Such as Figure 1 to Figure 6 Shown, a kind of waterproof coating preparation method, it has used multi-stage pulverizing equipment, and this multi-stage pulverizing equipment comprises pulverizing cylinder 1, primary pulverizing device 2 and multi-stage milling device 3, adopts this multi-stage pulverizing equipment to make waterproof coating The process also includes the steps of:
[0031] S1. Equipment inspection: Before starting the multi-stage crushing equipment, conduct routine inspections on the equipment;
[0032] S2. Preliminary crushing: sieve the waterproof coating raw materials through the primary crushing device 2, and crush the large particle raw materials;
[0033] S3, multi-stage crushing: the raw material after preliminary ...

The invention relates to a preparation method of waterproof paint. A multi-stage crushing device is used, the multi-stage crushing device comprises a crushing cylinder, a primary crushing device and a multi-stage grinding device, the primary crushing device is arranged on the inner wall of the upper end of the crushing cylinder, and the multi-stage grinding device is arranged on the inner ring face of the crushing cylinder. By means of the three stages of crushing processes in different modes, large-particle raw materials are crushed through beating, small-particle raw materials are crushed through extruding and grinding, then fine grinding is carried out, the waterproof paint is formed, and the problem that the raw materials with different particle sizes cannot be effectively crushed through the same crushing mode is solved. In the grinding process, reciprocating extrusion is adjusted, and therefore the grinding effect on the raw materials is improved, and meanwhile, the problem that the grinding effect and the material guiding speed are not achieved at the same time is solved.
Description
technical field [0001] The invention relates to the technical field of paint preparation, in particular to a preparation method of waterproof paint. Background technique [0002] Waterproof coating refers to a kind of coating that the coating film formed by coating can prevent rainwater or groundwater from seeping. The solid content refers to the proportion of solids contained in the waterproof coating. Since the coating film is formed by the solid components in the paint after brushing, the solid content is closely related to the film thickness and the quality of the coating film, and the particle size of the solid determines the quality of the coating film. [0003] The following problems often exist in the process of making waterproof coatings. First, because the particle size of the waterproof coating raw materials is not the same, in the process of crushing the waterproof coating raw materials, the raw materials with small particles form a buffer for the raw materials ...
