Embodiment 1

[0075] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 1m, spread it through a film spreading device, and coat the surface with a water-soluble adhesive polyacrylic acid, and then evenly coat the superabsorbent polymer material powder on the surface of the treated film, sprinkle The amount of powder is 3 g / ㎡, and after being coated with buckle glue, it is rolled up to obtain a single-layer product of concrete water-saving and moisturizing maintenance film with water absorption and water retention. It is used for the maintenance of poor concrete at the base of road concrete pavement, and there is no need for continuous watering during the maintenance period.

Embodiment 2

[0077] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 2m, unfold it through a film spreading device, coat the surface with a water-soluble adhesive polyvinyl formal, and then evenly coat the superabsorbent polymer material powder on the treated film surface Above, the amount of powder sprinkled is 6 g / ㎡, and after being coated with buckle glue, it is rolled up to obtain a single-layer product of concrete water-saving and moisturizing maintenance film with water absorption and water retention. watering.

[0078] The double-layer concrete water-saving and moisturizing curing film is based on the single-layer curing film, compounded with a layer of perforated plastic film, which can further lock the covering layer in the curing film, and at the same time improve the water-saving and moisturizing performance of the curing film . Its specific production process steps are:

[0079] 1. Unfold the plastic film with a thickness of 0.06-0.15mm and a w...

Embodiment 3

[0089] Take a high-pressure polyethylene film with a thickness of 0.08mm and a width of 2m, spread it through a film spreading device, punch holes, and coat the surface with a water-soluble adhesive polyvinyl formal, and then evenly coat the superabsorbent polymer material powder on the treated surface. On the surface of the film, the amount of powder sprinkled is 6 g / ㎡, and adhesive glue is applied, and then the unperforated plastic film is evenly combined with the perforated plastic film with super absorbent polymer materials on the surface to form a whole, and finally The double-layer concrete water-saving and moisturizing maintenance film is obtained by applying buckle glue and winding, which is used for the maintenance of highway concrete pavement, and does not need continuous watering during the maintenance period.

Abstract

The invention discloses a concrete curing film production technology and production equipment thereof. A plastic film is coated with a covering layer with super-strong water absorbing and retaining performance. The covering layer comprises a super-strong macromolecule water absorbing material and a bonding agent. The invention further discloses the concrete curing film production equipment. The concrete curing film production equipment comprises an unreeling device, a film expanding device, a punching device, a gluing device, a powder scattering device, a composite device and a reeling device. The plastic film is expanded into a single layer from a folded interlayer through the unreeling device, and the plastic film is tidied and conducted by the film expanding device to enter the subsequent procedure. The whole production line is in continuous variable transmission, and linkage is achieved. The concrete curing film produced through the technology is an update product of a traditional concrete curing material, the production technology of the concrete curing film is low in energy consumption, the production equipment is simple in structure, and construction is convenient. The equipment is high in automation degree and suitable for meeting the industrial requirement. A concrete water-saving moisturizing curing film of a single-layer structure can be produced, and a concrete water-saving moisturizing curing film of a double-layer structure can be produced as well.

Description

technical field [0001] The invention belongs to the concrete curing technology, and relates to a curing film production process which has a super-strong water absorption and water retention effect and is especially suitable for the maintenance of cast-in-place concrete in the engineering construction fields of roads, railways, water conservancy, dams, airports, ports, wind power generation, and house construction. and production equipment. Background technique [0002] The maintenance after concrete pouring is one of the key links in concrete engineering, and it has a great influence on the quality of concrete. The so-called curing refers to the technical measures taken to ensure the early hydration reaction of concrete after pouring to obtain predetermined physical and mechanical properties and durability. The main control parameters during the curing process are the temperature, humidity and curing time required to establish the hydration reaction. [0003] For a long ti...
