A kind of carpet-type environment-friendly high-efficiency mold release agent, its use method and its spraying device

Abstract

The invention discloses an environment-friendly and high-efficiency mold release agent for carpets, a use method and a spraying device thereof, and relates to the field of mold processing auxiliary technology, including a mold release agent, which is composed of the following components by weight percentage: 13% to 22% emulsified wax liquid , 18%~25% methyl silicone oil emulsion, 2%~5% modified silicone oil emulsion, 42%~47% deionized water, 2.5%~4% emulsifier, 0.2%~5% additive, 0.7%~1.2% Preservative, 1% to 3% stearamide. The spraying device includes a mechanical arm and a frame. Two groups of nozzles are symmetrically distributed at the bottom of the frame. The ends of the two groups of nozzles near the middle are hinged with the frame. The fulcrum at the hinge rotates; it also includes gears, which are arranged on the first round bar on the top surface of the hinged end of the nozzle and the frame. There is a horizontally movable double-sided rack in the middle of the gear, and the gear and the double-sided rack are meshed. After the spraying device of the present invention sprays the water-based release agent in the form of mist, the release effect of the product is greatly improved and the dosage 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
