Abstract
The present invention relates to an environment-friendly water-soluble building adhesive which is prepared from polyvinyl alcohol, polyethylene glycol, methylene di-naphthalene sodium, calcium chloride, sodium carbonate and water by a proper weight proportion through a certain process. The adhesive has the advantages of favorable workability, water preserving capability, high water resistance and durability after rigidification, strong adhesive force with various bases, no environment pollution and wide application range.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of construction work with water-soluble adhesive for building and preparation method thereof.
Background technology
Along with developing rapidly and the continuous lifting of Building technology of building industry, adhesive for building has the application of performance in construction work such as good interface cohesive force, water tolerance because of it very extensive, and application surface constantly enlarges.At present, adhesive for building mainly contains pulvis and aqua two big classes.Aqua is that the adhesive for building of main raw material(s) is built glue as 107 building glue, 801 with the polyvinyl formal, and it occupies great share on adhesive for building market.The sharpest edges of polyvinyl formal are cheap and of many uses, output improves constantly in two more than ten years in the past, use range constantly enlarges, and is widely applied the metope that interior decoration uses at present and criticizes the adhesive material of embedding material, wall floor tile, powdering material of wall face or the like.Because this class binding agent carries out condensation reaction by polyvinyl alcohol and formaldehyde and makes, artificial introducing formaldehyde is as raw material, and binding agent contains a certain amount of free formaldehyde.In production, construction and use, free formaldehyde constantly discharges, and influences IAQ (indoor air quality), and harmful HUMAN HEALTH, progressively the restriction cry that uses even ban use of grows to even greater heights.But this class binding agent is cheap, better performances, and range of application is wider.According to the existing condition of China, these binding agents still occupy certain market.
According to the demand and the strategy of sustainable development of China's Building technology development, develop water-soluble adhesive for building nontoxic, pollution-free, environment-friendly type and have great importance, not only have good economic benefit, and bring the huge social benefit.
Summary of the invention
The object of the present invention is to provide a kind of have good cohesiveness, workability, impermeability, pollution-free and competent water-soluble adhesive for building and preparation method thereof.
The water-soluble adhesive for building that the present invention proposes is made up of polyvinyl alcohol, polyoxyethylene glycol, calcium chloride, sodium metnylene bis-naphthalene sulfonate, yellow soda ash, water, and the weight proportion of each component is as follows:
Polyvinyl alcohol 10-30
Polyoxyethylene glycol 5-20
Sodium metnylene bis-naphthalene sulfonate 2-10
Calcium chloride 20-80
Yellow soda ash 0-5
Water 300-500
The preferable weight proportion of each component is
Polyvinyl alcohol 15-20
Polyoxyethylene glycol 10-15
Sodium metnylene bis-naphthalene sulfonate 4-8
Calcium chloride 50-60
Yellow soda ash 1-3
Water 430-480
Each component is prepared from water-soluble adhesive for building by following preparation technology.Wherein, also can add other auxiliary agents in the component and come adjusting function.Polyvinyl alcohol carries out aldolization but no longer add formaldehyde, but the multiple auxiliary agent of selecting other carries out modification to the molecule of polyvinyl alcohol, improves cohesive strength, viscosity, workability and the weather resistance of environment-friendly type building interfacial agents.The tackify component is the main ingredient in the interfacial agents, and the performance such as viscosity, flowability of adjustment being mixed the mortar mix of interfacial agents plays important effect.
Every technical indicator value of the water-soluble adhesive for building that experimental test goes out, product of the present invention in use, total organic volatile is few, meets the technical feature requirement of environment-friendly type building binding agent, is a kind of product of pollution-free, environmental type.
Water-soluble adhesive for building mixes in the sand-cement slurry in the 50%-60% ratio of cement consumption in use, mixes and stirs and can use.If to the demanding occasion of cohesive force, can suitably increase the usage quantity of binding agent.The stickup of finishing material is carried out in the agent of environment-friendly water-soluble architectural interface, has characteristics such as high-strength, high bonding, impervious, low contraction, weathering resistance and operating efficiency height, environmental pollution be little.Simultaneously, can also thoroughly solve difficult problems such as hollowing, shelling, cracking and skinning in construction requirement and seasonal variation by adjusting time of coagulation and the thickness performance that the composition material ratio obtains to suit.
Preparation method of the present invention is: at first, select suitable equipment such as reactor for use, conditions such as the whipped form of reactor and stirring velocity can satisfy certain requirement.Note adding time, adding speed and the material temperature control of dispersion agent, tackifier and stablizer etc. in the preparation process.
The preparation method is as follows: press each component of consumption proportion weighing, at first, polyvinyl alcohol is added in 70～95 ℃ of hot water, stir, until dissolving fully, be generally and stirred 100-150 minute; Adjust the temperature to 40-50 ℃ then, add polyoxyethylene glycol, and stir, carry out insulation reaction.Simultaneously, be dissolved in water in proportion hardening accelerator calcium chloride and other auxiliary agents; Treat that insulation finishes, pour dissolved solution into reactor, stir, promptly form product.
The invention has the advantages that:
(1) nontoxic, the no volatile organic content of product is harmless, free from environmental pollution, belongs to the quick patching material of environment-friendly type;
(2) Pei Zhi mortar has good workability, water-retentivity, has characteristics such as enhanced water resistance and weather resistance after the sclerosis;
(3) very strong with various bond matrix power, to compare with conventional cement mortar, cohesive strength increases substantially;
(4) applied range can be in construction requirement and climate change by adjusting time of coagulation and the thickness performance that the composition material ratio obtains to suit.
