Embodiment 1
[0012] The wood strip template release agent described in the present embodiment is made of the following raw materials:
[0014] The preparation method of the wood stripe formwork release agent described in the present embodiment comprises the following steps:
[0015] 1) Weigh 150kg of regenerated lubricating oil and 1kg of talcum powder and place them in a container;
[0016] 2) Stir the weighed regenerated lubricating oil and talcum powder at 15-30°C to make them wet and disperse evenly, dissolve and mix to form a white preparation without precipitation; after the preparation is formed, paint it on the strip template within 2 hours On the surface, after the preparation is formed, it should be painted on the surface of the strip formwork immediately, and the storage time should not exceed 2 hours, otherwise white precipitates will precipitate out. Before the next use, it must be stirred vigorously to completely...

Abstract
The invention relates to a mould release agent for a wood stripe moulding board, which comprises the following raw materials in weight portion: 150 portions of regenerative lubricating oil and 1 to 1.2 portions of talcum powder. A method for preparing the mould release agent for the wood stripe moulding board comprises the following steps: weighing the regenerative lubricating oil and the talcum powder according to required weight portion and placing the regenerative lubricating oil and the talcum powder in a utensil; and stirring the weighed regenerative lubricating oil and the talcum powder at a temperate of between 15 and 30 DEG C to wet and disperse the mixture evenly, and dissolving and mixing the mixture to form a deposit-free white preparation. The method has the advantages that because the talcum powder has better antisticking effect and flow aid effect, the talcum powder can fill concave parts on the surface of wood grain after being mixed with the regenerative lubricating oil, so as to avoid the wood grain from permeating concrete during casting the concrete; at the same time, the talcum powder has hydrophilicity and is mutually merged with slurry in the concrete, the wood grain is shown on the concrete surface clearly after a mould is removed, and the concrete surface is not easily strained when a moulding board is removed; and the method has simple processes, low cost and wide application, and the template for smoothening a common surface can be repeatedly used for about 10 times without being painted anew.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a release agent for wood stripe formwork. Background technique [0002] Concrete release agents are preparations that reduce or prevent the adhesion of concrete to formwork surfaces. In the process of concrete pouring, the product and the formwork stick together, which not only easily damages the product, but also makes it difficult to remove the formwork, resulting in high labor intensity and low production efficiency. Therefore, the use of release agents is crucial in concrete construction. The existing release agents at home and abroad are mainly two categories, one is oily release agents such as pure oil, emulsified oil paraffin, and the other is emulsion type release agents such as fatty acids. The above two types of release agents are mostly used in steel and wood templates with a high surface finish and a flat and smooth surface. The surface of the original ecological ...
