Detailed Description
The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the invention.
An adhesive for bonding a soundproof pad and a method for preparing the same according to the present invention will be described in detail below, wherein the adhesive for bonding a soundproof pad can eliminate the need for covering a thicker additional load of concrete and mortar on a floor; the concrete and mortar are not required to be pressurized and covered for a long time for maintenance, the sound insulation pad can be quickly adhered by a decoration unit, the construction is simple, only roller coating is required, and the efficiency is high; can directly paste sound insulation pad and floor on the ground of old building.
The adhesive for bonding the sound insulation pad comprises the following components in percentage by mass:
32-40% of styrene-butadiene latex emulsion;
0.2 to 0.4 percent of water-retaining agent;
0.8 to 1.2 percent of defoaming agent;
0.2 to 0.3 percent of wetting dispersant;
0.3 to 0.5 percent of acrylic thickener;
0.1 to 0.2 percent of cross-linking agent;
0.3 to 0.5 percent of film forming auxiliary agent;
35-50% of filler;
0.2 to 0.3 percent of resin-free color paste; and
15-20% of water.
Preferably, the adhesive for bonding the sound insulation pad comprises 0.1 to 0.5 mass percent of sterilization mildew inhibitor. The bactericidal mildew preventive may be implemented as MICROBAN AF FLOWABLE.
According to an embodiment of the present invention, the styrene-butadiene latex emulsion is implemented as a nano-scale self-crosslinking styrene-butadiene rubber emulsion.
The styrene-butadiene latex emulsion used in the invention is a nanoscale self-crosslinking styrene-butadiene rubber emulsion, and is preferably 50 nm-200 nm. The nano-scale self-crosslinking styrene-butadiene rubber emulsion with small particle size is beneficial to the penetration of emulsion particles to a concrete base layer and a sound insulation pad and improves the bonding strength. If the particle size of the self-crosslinking styrene-butadiene rubber emulsion is too large, the permeation and reinforcement of the self-crosslinking emulsion can be affected. Meanwhile, the compactness of the film is reduced due to the overlarge grain diameter, and the waterproof and moistureproof performances of the adhesive film are affected. The nanoscale self-crosslinking emulsion is implemented as an emulsion selected from styrene-butadiene rubber.
It is worth mentioning that the selected nanoscale self-crosslinking styrene-butadiene rubber emulsion has a self-crosslinking function at room temperature, can further realize the adhesion of the adhesive to the concrete base layer and the sound insulation pad, and improves the cohesive strength of the material.
The adhesive for bonding the sound insulation pad comprises the following additives. The additive comprises 0.2 to 0.4 percent of water retention agent, 0.8 to 1.2 percent of defoaming agent, 0.2 to 0.3 percent of wetting dispersant, 0.3 to 0.5 percent of acrylic thickener, 0.1 to 0.2 percent of cross-linking agent, 0.3 to 0.5 percent of film forming auxiliary agent, 35 to 50 percent of filler, 0.2 to 0.3 percent of resin-free color paste, 0.2 percent of sterilization mildew inhibitor and 15 to 20 percent of water.
It is worth mentioning that the water retaining agent may be implemented as hydroxyethyl cellulose ether HBR250. The defoamer may be implemented as a polymer Form Star BP 2706. The crosslinking agent may be implemented as a silane coupling agent MP 200. The wetting dispersant may also be a TRITON X-405; the bactericidal mildew preventive may be implemented as MICROBAN AF FLOWABLE; the film forming aid may be implemented as DOWANOL DPNB.
The wetting and dispersing agent plays an important role in dispersion stability of the filler and pigment, and further improves wetting and penetration of the concrete base layer and the sound insulation pad by reducing surface tension of the adhesive, so that adhesive strength between the sound insulation pad and a concrete base surface is improved.
The crosslinking agent can stably disperse and store substances in an aqueous system. And the subsequent reaction with the latex particles and functional groups in the basal plane, such as hydroxyl, carboxyl, amino and the like, can be further carried out at room temperature, so as to improve the adhesion of the sound insulation pad and the concrete basal plane.
The sound insulation pad adhesive has waterproof and moistureproof functions, and the self-crosslinking styrene-butadiene rubber emulsion can form a compact polymer film while adhering concrete and sound insulation pads, so that the entry of moisture and water vapor is prevented, and the purposes of waterproof and moistureproof are achieved.
And the thickener system of the sound insulation pad adhesive is formed by selecting an alkali swelling thickener and a modified cellulose ether water-retaining agent thickener to be matched for use. The proportion of the alkali swelling thickener to the modified cellulose ether water-retaining agent thickener is 3:1, so that the materials are stored in the barrel without layering, bleeding and precipitation, sagging and splashing during construction, and a certain construction thickness is ensured. If the cellulose ether is added in a higher proportion, the problems of difficult dispersion in production, poor product storage property, uneven coating film and the like can occur; if the alkali swelling thickener is higher, the storage stability is poor, the workability is poor, and the like.
The sound insulation pad adhesive also comprises 0.2-0.3% of water-based color paste, preferably water-based resin-free color paste. The color of the sound insulation pad adhesive can be prepared by aqueous color paste, and preferably, the aqueous resin-free color paste can avoid negative influence of resin in a color paste system on system stability.
According to another aspect of the present invention, there is provided a method for preparing an adhesive for a soundproof pad, comprising the steps of:
adding 15-20% of water and 0.2-0.4% of water-retaining agent into the reaction kettle according to the measured parts, stirring at 100-200 rpm for 5min;
adding 0.8-1.2% of defoaming agent, 0.8-2% of wetting dispersant and 35-50% of filler into the reaction kettle, stirring at 800-900 rpm for 20min. Finally, adding 32-40% of styrene-butadiene latex emulsion, 0.3-0.5% of film forming additive, 0.2-0.3% of resin-free color paste and 0.2% of sterilization mildew inhibitor into a reaction kettle, and stirring for 30min at 800-900 rpm; the temperature in the stirring kettle is controlled within 40 ℃ in the whole production process, and finally the vacuum packaging is carried out.
