Abstract

The invention discloses a kind of anhydrous polyurethane glue spraying of double-component, belong to adhesive area.It is formulated by following components according to mass percent：Castor oil 25~35%, PEPA 10~20%, coarse whiting 40~50%, methyl diphenylene diisocyanate（MDI）0.3~0.8%, diluent 3~8%, calcium oxide 1.8~2.5%, white carbon 0.5~1.5%, fire retardant 0.5~1.5%, defoamer 0.1~0.3%.For black and white glue, one-component foamed glue, its intensity is higher, weatherability is more preferable；Can only manually for the double-component anhydrous polyurethane adhesive of scraper relative at present, it can automatically be sprayed by machine, and production capacity is greatly improved.

Description

A kind of anhydrous polyurethane glue spraying of double-component
Technical field
The present invention relates to a kind of anhydrous polyurethane glue spraying of double-component, belong to adhesive area.
Background technology
Under the main trend of Chinese energy-saving and emission-reduction, the passage that building energy-saving standard will be with the time is improved constantly, people Also constantly strengthening for quality, environmental protection, awareness of safety, the development of Green energy-saving buildings, the propulsion of housing industrialization, building makes With the raising in life-span, heat-insulating construction material energy-conserving and environment-protective etc., these are all closely bound up with energy saving, mitigation environmental pollution.Build Building energy-conservation has turned into the key factor of influence China energy sustainable development strategic decision, the development of environment protection type high-strength adhesive Then turn into the developing direction of the research field with exploitation.
At present, at home in heat-preserving building purification plate materials industry, industrial adhesive mainly has black and white glue, one-component hair Bubble glue, the class glue of double-component anhydrous polyurethane adhesive three.Black and white glue and one-component foamed glue both adhesive features are machine sprays Apply production capacity high, 1 daily square meter purification plate of 8 hours production capacities about 3000 of 1 group of the people of equipment 5, but major defect is low intensity, it is weather-proof Property, fire protecting performance are poor.According to JC/T2113-2012 aluminium honeycomb composite plate standard detection used for building exterior wall, flatwise tensile strength data are only There is 0.2MPa or so, fire protecting performance can only achieve B2 grades.
And double-component anhydrous polyurethane adhesive intensity, the weatherability of in the market are lifted more than on the basis of 2 kinds of adhesive About 60%, intensity according to JC/T2113-2012 aluminium honeycomb composite plate standard detections used for building exterior wall, flatwise tensile strength data >= 0.6MPa, fire protecting performance reaches B1 grades.But major defect is artificial frictioning, production capacity is low, and 11 group of people daily 8 of equipment 6 is small When the square meter purification plate of production capacity about 200, cause manufacturing cost remain high.
The content of the invention
The technical problems to be solved by the invention are：There is provided a kind of double-component anhydrous polyurethane glue spraying, it solves mesh Preceding double-component anhydrous polyurethane adhesive needs artificial frictioning, the low problem of production capacity.
The technical problems to be solved by the invention take following technical scheme to realize：
A kind of anhydrous polyurethane glue spraying of double-component, it is formulated by following components according to mass percent：Castor oil 25~ 35%, PEPA 10~20%, coarse whiting 40~50%, methyl diphenylene diisocyanate（MDI）0.3~0.8%, diluent 3 ~8%, calcium oxide 1.8~2.5%, white carbon 0.5~1.5%, fire retardant 0.5~1.5%, defoamer 0.1~0.3%.
The beneficial effects of the invention are as follows：For black and white glue, one-component foamed glue, its intensity is higher, weatherability More preferably；Can only manually for the double-component anhydrous polyurethane adhesive of scraper relative at present, it can automatically be sprayed by machine, be produced Can greatly improve.
Specific embodiment
In order to be easy to understand to technological means of the invention, creation characteristic, reached purpose and effect, further below Illustrate the present invention.
A kind of anhydrous polyurethane glue spraying of double-component, it is formulated by following components according to mass percent：Castor oil 25 ~35%, PEPA 10~20%, coarse whiting 40~50%, methyl diphenylene diisocyanate（MDI）0.3~0.8%, diluent 3~8%, calcium oxide 1.8~2.5%, white carbon 0.5~1.5%, fire retardant 0.5~1.5%, defoamer 0.1~0.3%.
Preparation method：
By castor oil, PEPA and methyl diphenylene diisocyanate（MDI）High-shear emulsifying is added to according to the above ratio Emulsified uniformly at a high speed in machine, then put into high-power mixer material, be slowly uniformly added into white carbon, calcium oxide, weight Dispersion stirs at a high speed for calcium, diluent, defoamer, fire retardant, and the anhydrous polyurethane spray of double-component of >=99% solid content is obtained Glue, stirs with 40 MDI curing agent by the anhydrous polyurethane glue spraying 100 of double-component when using and uses.
Wherein, high-shear emulsion machine, using PKIF400 type high-shear emulsion machines；High-power mixer is used, JB500D types High-power mixer.
