Abstract
This invention relates to a waterproof material for construction, especially poly (vinyl butyral) waterproof material. The waterproof material is composed of: poly(vinyl butyral) 60-80 wt.%, Fe2O3 8-10 wt.%, Al(OH)3 3-5 wt.%, CaCO3 3-5 wt.%, talcum powder 3-5 wt.%, laterite 3-5 wt.%, and quartz sand 3-5 wt.%. The product has such advantages as good waterproof property and low price. Part of the raw materials are recovered wastes, thus this invention is environmentally friendly.
Description
Technical field
The present invention relates to a kind of construction work water-proof material, particularly adopt the formed water-proof material of polyvinyl butyral acetal, it belongs to the construction engineering waterproof material technical field.
Background technology
At present, existing general architectural waterproof material mostly is SBS waterproof roll random level propylene waterproof roll and EPDM rubber waterproof rolling material etc.The present production cost of above-mentioned water-proof material, selling price is generally higher, and along with International Crude Oil is lasting high, this inferior position is more and more obvious.Chinese invention patent publication number 1472266A discloses " a kind of polyvinyl acetal acid-and alkali-resistant and washing resistant paint ", Chinese invention patent publication number 1422930A discloses " a kind of new water repellent ", although the disclosed technical scheme of above-mentioned two pieces of documents has all adopted the polyvinyl butyral acetal raw material, but they are a kind of paint and water-resisting agents that apply usefulness, rather than a kind of water-proof material, particularly in order to increase the derusting rust-proofing ability, use many acidic substance, changed product performance and cost.
Summary of the invention
Purpose of the present invention be exactly for fear of with the shortcoming and defect that overcomes prior art, and provide a kind of novel waterproofing material of polyvinyl butyral acetal, it is raw material that the present invention adopts cheap polyvinyl butyral acetal tankage, cooperates other auxiliary materials to process water-proof material, cheap.The waste material that has rationally solved in the PVB process for processing utilizes problem on the one hand, has saved the cost of Treatment of Waste Plastics, has eliminated the problem of environmental pollution that is brought by plastic waste on the other hand, has realized the purpose that turns waste into wealth.At present, each is produced and utilizes the producer of PVB to have a large amount of PVB tankage (waste material).Our purpose is to produce high-quality PVB water-proof material by rational technology, and this product is a water-proof material inexpensive on the market.
The present invention realizes its goal of the invention by the following technical solutions.
Waterproofing material of polyvinyl butyral acetal, it is made up of following raw materials according: polyvinyl butyral acetal, red iron oxide, aluminium hydroxide, lime carbonate, talcum powder, laterite, quartz sand.The per-cent that described raw material is formed is as follows: polyvinyl butyral acetal 60-80%, red iron oxide 8-10%, aluminium hydroxide 3-5%, lime carbonate 3-5%, talcum powder 3-5%, laterite 3-5%, quartz sand 3-5%.The per-cent that raw material of the present invention is formed can also be as follows: polyvinyl butyral acetal 70%, red iron oxide 10%, aluminium hydroxide 4%, lime carbonate 4%, talcum powder 4%, laterite 4%, quartz sand 4%.And be chosen as the 0.5-4.0 millimeter with the water-proof material thickness of extruder for shaping through Rubber processing.
The present invention utilizes polyvinyl butyral acetal and red iron oxide to be main raw material, is equipped with auxiliary material aluminium hydroxide, talcum powder, lime carbonate, quartz sand and laterite etc., adopts Banbury mixer to make the abundant mixing of above-mentioned raw materials, through the Rubber processing extruder for shaping.Utilize the formed product of the technology of the present invention to have the advantage of water resistance excellence, cheap, utilization of waste material, protection environment.
Embodiment
Prepare raw material according to technical solutions according to the invention, and dispose raw material: polyvinyl butyral acetal 70%, red iron oxide 10%, aluminium hydroxide 4%, lime carbonate 4%, talcum powder 4%, laterite 4%, quartz sand 4% by following per-cent.
With polyvinyl butyral acetal section and input Banbury mixer, heating up makes it molten.Drop into lime carbonate, talcum powder, aluminium hydroxide, red iron oxide, laterite, quartz sand successively, and mix.Cooling is also passed through extruder for shaping.
Wherein main raw material polyvinyl butyral acetal elastomerics is the waterproof bonding material as the basis.Because of a large amount of polyvinyl butyral acetal tankage colors mixes, so the present invention introduces red iron oxide and makes water-proof material color homogeneous.In order to make this water-proof material have excellent fire resistance, the present invention utilizes inexpensive aluminium hydroxide as fire retardant.Other inorganic auxiliary material: lime carbonate, talcum powder, quartz sand and laterite use as adding material, to reach the purpose that reduces cost.
The advantage that the present invention gives prominence to is for turning waste into wealth, and both product of the present invention was by a large amount of PVB leftover bits and pieces Process with waste material, cheap, protection of the environment. Has quite outstanding social benefit and economy Benefit.
