Environment-friendly and efficient release agent for carpets and using method and spraying device of environment-friendly and efficient release agent

Abstract

The invention discloses an environment-friendly efficient release agent for carpets and a using method and a spraying device of the environment-friendly efficient release agent, and relates to the technical field of mold processing assistance. The release agent is prepared from the following components in percentage by weight: 13%-22% of emulsified wax liquid, 18%-25% of methyl silicone oil emulsion, 2%-5% of modified silicone oil emulsion, 42%-47% of deionized water, 2.5%-4% of an emulsifier, 0.2%-5% of an additive, 0.7%-1.2% of a preservative and 1%-3% of stearamide. The spraying device comprises a mechanical arm and a machine frame, two groups of nozzles are symmetrically distributed at the bottom end of the machine frame, the ends, close to the middle, of the two nozzles are hinged to the machine frame, and the nozzles can rotate along fulcrums at the hinged positions of the nozzles and the machine frame. The spraying device further comprises a gear, the gear is arranged on a first round rod arranged on the top face of the end, hinged to the machine frame, of the nozzles, a double-face rack capable of horizontally moving is arranged in the middle of the gear, the gear is connected with the double-face rack in a meshed mode, after the water-based mold release agent is sprayed out in a mist mode through the spraying device, the mold release effect of a product is greatly improved, and the use amount is greatly reduced.

Description

technical field [0001] The invention belongs to the field of mold processing auxiliary technology, and in particular relates to an environmentally friendly and high-efficiency mold release agent for carpets, a use method and a spraying device thereof. Background technique [0002] The mold release agent is mainly used in the production process of polyurethane products after pouring and molding; it can give most polyurethane molds a good mold release effect. The existing carpet foam products mainly use oil-based release agents. Although oil-based release agents are easy to release from the mold and not easy to get dirty, they also have obvious disadvantages: unqualified VOC, relatively more harmful substances, and the surface of the product is easy to Foaming and delamination will produce residues on the product, affecting the quality of the product. It is imperative to replace the water-based release agent when customers have increasingly stringent requirements on odor and ...

Problems solved by technology

The existing carpet foam products mainly use oil-based release agents. Although oil-based release agents are easy to release from the mold and not easy to get dirty, they also have obvious disadvantages: unqualified VOC, relatively more harmful substances, and the surface of the product is easy to Foaming and delamination will produce residues on the product, affecting the quality of the product

[0003] The water-based release agent is characterized by using water as the dispersed phase, and the formed water-soluble product not only has the function of releasing the polyurethane foam, but also has biodegradability, no harmful substances such as VOC, and is environmentally friendly; and water is used as a diluent, It is non-polluting, easy to obtain, and low cost. The existing release agents are usually sprayed or smeared in the mold cavity by manual spraying equipment or rags. The work efficiency is low and the uniformity is poor. Therefore, we propose a carpet Environment-friendly and high-efficiency release agent, method of use and spraying device thereof
