Problems solved by technology

[0002] Foam, leather and other chemical materials are widely used in the surface protection and decoration of automobiles, furniture and other building materials due to their light weight and easy molding. However, because the simple foam or leather layer has poor waterproof and wear-resistant effects, it affects its protective decoration effect and service life; foam materials are more so, and their tensile strength is poor
How to effectively increase the waterproof and wear-resistant effect of such materials has become a research hotspot in the industry. The existing main method is to paste a waterproof and wear-resistant layer on the surface of foam, leather and other materials to increase its surface protection and decorative effects. At the same time, its tensile strength is increased; but this method has two shortcomings: one is that a large amount of glue is used, which is costly and not environmentally friendly; the other is that the thickness is greatly increased, which affects its decorative effect to a certain extent

Embodiment 1

[0038] Fully mix 40Kg diphenylmethane diisocyanate, 40Kg polyether polyol and 2Kg colorant in a mixer, then prepare the foam base material, prepare the release paper, coat the coating, apply the release paper, heat cure, Steps such as cooling obtain composite coating product. The thermal curing temperature is 25° C., and the coating thickness of the finally obtained composite coating material is 0.1 mm.

Embodiment 2

[0040] Fully mix 50Kg diphenylmethane diisocyanate, 49Kg polyether polyol and 1Kg colorant in a mixer, then prepare the foam substrate, prepare the release paper, coat the coating, apply the release paper, heat cure, Steps such as cooling obtain composite coating product. The thermal curing temperature is 30° C., and the coating thickness of the finally obtained composite coating material is 0.5 mm.

Embodiment 3

[0042] Fully mix 58Kg diphenylmethane diisocyanate, 40Kg polyether polyol and 2Kg colorant in a mixer, then prepare the leather substrate, prepare the release paper, apply the coating, apply the release paper, heat cure, and cool and other steps to obtain composite coating products. The thermal curing temperature is 40° C., and the coating thickness of the finally obtained composite coating material is 1 mm.

[0043] The composite coating material produced by the method of the invention has significantly enhanced tensile strength, waterproof and abrasion resistance.

Abstract

The invention discloses a method for manufacturing a composite coating material, which belongs to the field of material manufacturing and processing technology, and mainly comprises a) confecting coating material, abundantly stirring and mixing 40 wt percent-58 wt percent of diphenylmethane di-ethylene rhodanate, 40 wt percent-58 wt percent of polyether polyol and 1 wt percent-2 wt percent of minim colorant; putting mixed coating material in a coating material device; b) preparing base material; c) preparing release paper; d) spreading the coating; e) covering the release paper; f) thermal curing; g) cooling; h) obtaining composite coating product, and the like procedures. The method for manufacturing a composite coating material has simple craft and method; the manufactured product is pro-environment; waterproof and wear resistance are good.

Description

Technical field: [0001] The invention belongs to the technical field of material production and processing, and in particular relates to a production method of a composite coating material. Background technique: [0002] Chemical materials such as foam and leather are widely used in the surface protection and decoration of automobiles, furniture and other building materials due to their light weight and easy molding. It is not good, which affects its protective decoration effect and service life; especially for foam materials, its tensile strength is poor. How to effectively increase the waterproof and wear-resistant effect of such materials has become a research hotspot in the industry. The existing main method is to paste a waterproof and wear-resistant layer on the surface of foam, leather and other materials to increase its surface protection and decorative effects. At the same time, its tensile strength is increased; but this method has two shortcomings: one is that a...
