Problems solved by technology

However, the conductivity, heat resistance and solvent resistance are not as good as inorganic zinc-rich primers
However, the use of inorganic zinc-rich requires water vapor curing, and the recoating interval is very long at room temperature. There are many pores on the surface of the substrate, and it is easy to foam when the topcoat is applied, with poor adhesion and easy peeling
Therefore need a kind of water-based workshop precoating primer to combine respective advantages, and the production equipment of this organic-inorganic hybrid primer in the prior art can't realize automatic feeding well, generally all are sent directly to by conveying Put it into a bucket, and then pour it into the reactor, and the weight and type of raw materials and the order of feeding raw materials rely on manual control, and in some automated production equipment, the weight and feeding order of raw materials cannot be well fed back, and it is easy to appear Poor primer performance due to inaccurate sequencing and weight dosing, which can even lead directly to scrap

Abstract

The invention discloses a preparation method of a water-based workshop pre-coating primer. The steps include S1. The raw materials of the pre-coating primer include 30-40 parts of inorganic hybrid resin, 40-50 parts of 800-mesh zinc powder, and 5 parts of zinc phosphate. ‑8 parts, 2‑5 parts of nanomaterials, 0.5‑1.5 parts of anti-flash rust agent, 0.5‑1 part of dispersant, the raw materials of the above components are respectively packed in corresponding raw material barrels; S2. The inorganic hybrid resin, dispersant, nano-material and anti-flash attractant in the raw material barrel are put into the reaction kettle in sequence, starting from the dispersant, each raw material is put in, and specific reaction conditions are controlled to obtain a semi-finished product Primer; S3, and then stir with 800-mesh zinc powder and zinc phosphate to obtain a finished primer. The finished product prepared by the method has better mechanical properties, and can better resist chemical and physical reactions caused by environments such as temperature and humidity. The invention also provides a preparation device for the precoating primer, which realizes automatic production with intelligent and precise control.

Description

technical field [0001] The invention relates to the field of shop precoat primers, more specifically, it relates to a preparation method and a preparation device of a water-based shop precoat primer. Background technique [0002] The workshop primer is a layer of antirust paint sprayed on the assembly line after the steel plate or section steel has been pretreated by shot blasting to remove rust. The function is to protect the surface of the shot blasted steel and prevent the corrosion damage caused by the rust of the steel during processing and ship construction. Water-based shop primers have high requirements on rust resistance, and zinc-added shop primers are generally used, which have good heat resistance, outstanding rust resistance, and good compatibility with other coatings. [0003] In the prior art, the organic water-based workshop pre-coating primer has better mechanical properties, thicker coating film, lower surface treatment requirements than inorganic type, an...
