Description

Durable type trucd mixer chute

Technical Field

The utility model relates to a durable type trucd mixer chute belongs to engineering vehicle technical field.

Background

In the concrete pumping process, concrete in a mixing drum of the concrete mixer truck enters a hopper of the pump truck through a chute and is pumped to a construction pouring interface. In the process, part of concrete is easy to accumulate on the chute at the outlet of the mixing drum, and the chute shell needs to be vibrated to slide the accumulated concrete out of the chute. Whether the materials are vibrated in the pumping process or hardened concrete remained on the chute is cleaned after work, the chute needs to be knocked. Therefore, the traditional chute with the surface spraying protection is easy to collide with and deform and the paint falls off and is corroded, so that the chute is poor in durability and short in service life.

At present, a mould pressing plastic lining is additionally arranged on a chute shell abroad to realize the protection function. However, the technology needs to additionally increase a molded plastic liner, the molded plastic is relatively complex to manufacture, a mold and hot-press molding equipment are needed, and the manufacturing cost is high; and the molded plastic lining and the chute are only connected by bolts, so the molded plastic lining is not firm enough, is easy to fall off after long-term use and is inconvenient to maintain.

Therefore, a need exists for a new durable mixer truck chute that provides good protection.

Disclosure of Invention

An object of the utility model is to overcome the aforesaid not enough, provide a simple structure, preparation convenience, with low costs, protective properties is good, non-maintaining durable type trucd mixer chute.

The purpose of the utility model is realized like this:

the utility model provides a durable type trucd mixer chute, contains the chute body of installing in concrete mixer concrete exit, and its transversal U-shaped of personally submitting is equipped with priming paint layer and polyurea inoxidizing coating in proper order outside the U-shaped outside top layer of chute body from inside to outside.

Furthermore, a primer layer and a polyurea protective layer are sequentially arranged on the U-shaped inner side surface layer of the chute body from inside to outside.

Further, the thickness of the primer layer is 40-50 μm.

Further, the primer layer is a two-component high-solid epoxy resin primer.

Further, the thickness of the polyurea protective layer is 2 mm-3 mm.

Furthermore, the polyurea protective layer is formed by reacting polyaspartic acid ester and isocyanate curing agent.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses simple structure, spraying preparation are convenient and with low costs, utilize anticorrosive, waterproof, the impact resistance of polyurea coating, make the chute not receive to collide with to strike and warp, and the priming paint layer can further improve the adhesion force who improves the polyurea coating, prevents that the polyurea coating from droing when knocking the vibration, extension chute life, improvement chute durability, non-maintaining.

Detailed Description

Referring to fig. 1 to 3, the durable mixer truck chute of the present invention comprises a chute body 1 installed at a concrete outlet of a concrete mixer truck, wherein the cross section of the chute body 1 is U-shaped, and a primer layer 2 and a polyurea protective layer 3 are sequentially arranged on the outer side and the inner side surface layer of the U-shaped chute body 1 from inside to outside; the primer layer 2 is a bi-component high-solid epoxy resin primer, the thickness of the primer layer is 40-50 mu m, and the bonding force between the chute body 1 and the polyurea protective layer 3 is improved.

The polyurea protective layer (3) is formed by reacting polyaspartic acid ester and an isocyanate curing agent, and the thickness of the polyurea protective layer is 2-3 mm. Polyurea is an elastomeric substance formed by the reaction of an isocyanate component and an amino compound component, and the most basic characteristics of polyurea are corrosion resistance, water resistance, abrasion resistance and the like. The technology of spraying Polyurea Elastomer (SPUA for short) is a novel universal coating technology, the Polyurea coating is more flexible, has enough rigidity and rich colors, is compact, continuous and seamless, completely isolates the permeation of moisture and oxygen in the air, has incomparable corrosion resistance and protective performance, and simultaneously has multiple functions of wear resistance, water resistance, impact resistance, fatigue resistance, aging resistance, high temperature resistance, nuclear radiation resistance and the like.

The existing coating technology mainly comprises paint spraying and powder spraying, and can solve the problems of corrosion resistance and appearance. With the development of the engineering machinery industry, the coating purpose is not limited to corrosion prevention and decoration, and is gradually expanded to the aspects of collision prevention, dirt prevention and the like.

The polyurea protective coating material is a high-molecular elastic coating functional material and is formed by mixing a high-molecular prepolymer and a functional resin compound and then spraying the mixture at high pressure. The coating has elastic and high-strength macromolecular network, has strong polarity and hydrogen bonds, can enhance intermolecular acting force, has strong adhesive force and wrapping property, and prevents the generation and the transverse expansion of cracks near a stress point. Because the intermolecular crosslinking density is high and the structure flexibility is good, the material has outstanding strength and toughness, and can realize the rapid strengthening and the super-toughness protection of the structure.

In this embodiment, the polyurea protective material coating is sprayed on the chute, and the spraying thickness is 2 mm to 3 mm, so that the chute has the functions of impact resistance and wear resistance, and the specific implementation process includes: firstly, performing shot blasting bottom treatment on the chute body 1, then spraying primer with the thickness of 40-50 mu m, and finally spraying polyurea material with the spraying thickness of 2-3 mm, wherein the polyurea material is cured within half a minute after being sprayed, and the polyurea material is free from being dried, simple to manufacture and low in cost.

By utilizing the corrosion resistance, the water resistance and the impact resistance of the polyurea coating, the outer side of the chute is not deformed by collision and knocking, and the inner side of the chute improves the wear resistance; the primer layer can further improve the adhesion bonding force of the polyurea coating and prevent the polyurea coating from falling off when knocking and vibrating, thereby prolonging the service life of the chute, improving the durability of the chute and avoiding maintenance when the chute is used at ordinary times.

In addition: it should be noted that the above-mentioned embodiment is only a preferred embodiment of the present patent, and any modification or improvement made by those skilled in the art based on the above-mentioned conception is within the protection scope of the present patent.
