Abstract
The present invention relates to one kind of dry mixed mortar with polyacrylic acid powder adhesive, and the dry mixed mortar consists of cement 25-30 wt%, additive 0.3-0.5 wt% and sand 70-85 wt%. The additive consists of adhesive 60-70 wt%, retarder 20-35 wt%, and tackifier 5-7 wt%. The dry mixed mortar is mixed with water before being used. The present invention has reduced cement and additive consumption and lowered cost.
Description
The art field
The present invention relates to a kind of building adhesive, the application of particularly a kind of polyacrylic acid powder and similar polymer adhesive in dry-mixed mortar.
Background technology
Because the building trade of China is all developed as other all trades and professions in recent years fast.Just because of this, some new technologies, novel material continue to bring out, and some technology, materials conservative, that fall behind progressively are eliminated; Because these technologies that fall behind, the needs of the current architectural development of material incompatibility.For example: when deposit concrete, wooden model, the punching block of outside usefulness all must be coated machine oil, when form removal, have a spot of machine oil to stay concrete surface, must remove, otherwise the easy hollowing of the mortar that powder gets on, thus have use alkali cleaning, use manual handling, so both wasting manpower and material resources, delay the construction period again, also undesirable sometimes at last, quality can not get ensureing.
The interfacial agents of the domestic use of China has two big classes at present, and a class is the cement based interfacial agents, and for example: what ground such as Shanghai, Changzhou, Nanjing were used all is the cement based interfacial agents; Another kind of is macromolecule emulsion type interfacial agents, for example: epoxy oil-in-water type, EVA emulsion-type, the ACRYLIC EMULSION type that produce in Beijing, as the YJ-302 that produce in Beijing, YJ-303, DJ-601 is divided into two kinds of two-pack, single components again in the oil-in-water type.
Generally speaking, the interfacial agents of oil-in-water type is better than cement based, from the requirement of bonding strength, waterproof, basic unit, does not resemble the cement based tighter to basic level requirement.The common drawback of these two kinds of interfacial agents is: substrate surface will be sprayed water, interfacial agents was coated after 20 minutes must smear mortar, the two-pack emulsion-type interfacial agents of producing as Beijing in use, do not wait drying will smear mortar, mortar must maintenance, and also has certain shortcoming in production process and use.
The light cinder brick interfacial agents is made up of cement, yellow sand and other weighting agents, several parts of additive.Traditional main body additive raw material is a methylcellulose gum, adds retardant, and multiple industrial chemicals such as water-holding agent is formed, for reaching requirement of strength, cement consumption must be more than 40%, and yellow sand is an inclusion-free washing quartz sand, raw materials cost is higher, and price per ton is about 1000 yuan.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art, and a kind of polyacrylic acid powder and similar polymer adhesive is provided, and adds a small amount of other chemical materialss composition additives.
Task of the present invention is achieved in that
1. cement 25～30%
2. additive 3～5 ‰
3. yellow sand 70～85%
Wherein the composition of additive and content are:
4. tackiness agent 60～70%
5. retardant 20～35%
6. tackifier 5～7%
The percentage ratio that is adopted among the present invention is weight percentage.The present invention at present can be made in the multiple dry-mixed mortars such as concrete interface agent, ceramic tile, marble, stone material tackiness agent and aerated-block tackiness agent, and said ratio also is meant the proportional difference in above-mentioned several products.
Take by weighing starting material by above-mentioned formula rate, will 4. 5. 6. mix being made into 2. component of additive, will 1. 2. 3. mix, add the water stirring and use.Thereby tackiness agent is substituted methylcellulose gum, obtain required polyacrylic acid powder and similar polymer adhesive.
The present invention has following advantage compared to existing technology: because the present invention rejects yellow sand in combination, bought voluntarily by unit in charge of construction, product of the present invention has reduced the man-hour more than 70%, energy consumption, transportation, Packing Fee in the production and sales.Under the prerequisite of ensuring the quality of products, reduce cement and additive amount, cost can be declined to a great extent, and the product innovation that is better than traditional product only need just can be used with half left and right sides price by unit in charge of construction.Such as the interfacial agents with product mix of the present invention, substrate surface need not water spray during construction, coats interfacial agents and whenever all can smear mortar.
Embodiment:
The specific embodiment of the invention sees Table (content is weight percentage):
Claims (2)
1. a polyacrylic acid powder and similar polymer adhesive adds other chemical materialss and forms additive, and its component and content are:
1. cement 25～30%
2. additive 3～5 ‰
3. yellow sand 70～85%
The percentage ratio that is adopted among the present invention is weight percentage.
2. according to a kind of polyacrylic acid powder and similar polymer adhesive of claim 1, it is characterized in that the composition of its additive and content are:
4. tackiness agent 60～70%
5. retardant 20～35%
6. tackifier 5～7%
To 4. 5. 6. mix being made into 2. component of additive, will 1. 2. 3. mix, and add the water stirring and use.
