Description
Technical field
The present invention relates to a kind of water-proof sheet material, particularly a kind of waterproof chipboard, belongs to Furniture panel field.
Background technology
At present, the class in water-proof sheet material is to apply water-repellent paint on common sheet material.Waterproof material has two large classes: the one, and polyurethane kind water-repellent paint.This class material is to be generally made up as raw material of polyurethane and coal tar.The tar gas toxicity that it volatilizees is large, and is not easy to remove, but in the time using this coating, general employing contains the organic solvent such as toluene, dimethylbenzene dilutes, thereby also containing toxic; Another kind of is polymer cement-base waterproof coating.The emulsion that it is synthesized by multiple waterborne polymeric forms with the high grade cement that is mixed with various additives, and the flexibility of polymer (resin) and the rigidity of cement became one, and makes its performance aspect impervious and stability excellent.Its advantage is that easy construction, comprehensive cost are low, and asepsis environment-protecting.Therefore, polyalcohol cement basis has become the leading role in water-repellent paint market.
Emerging a kind of water-repellent paint is in coating, to add water-repelling agent at present.Water-repelling agent is after scientific and technical surface modification treatment, is dispersed in water and forms stable dispersion, adds in coating and can form a kind of special water resistant structure at coating film formation surface, makes surface have extremely strong hydrophobic, hydrophobic, waterproof, raising taste masking effect.Generally comprise organic silicon hydrophobic agent and water-based hydrophobic agent.Two kinds of water-repelling agents all utilize the feature performance hydrophobic effect of raw material itself, and hydrophobic effect is undesirable or gas permeability is poor.
Particieboard is the fragment that the raw material such as timber is cut into certain specification, through super-dry, mixes with adhesive, curing agent, waterproofing agent a kind of artificial board that compacting forms at a certain temperature.Because particieboard structure is more even, good processability, can be processed into the sheet material of large format as required, is the good raw material of furniture of making different size, pattern.Manufactured goods particieboard does not need to be again dried, and can directly use, and sound-absorbing and sound insulation value are also fine.But it also has its intrinsic shortcoming, since edge roughness, easily moisture absorption.Because particieboard volume is larger, use its Hepplewhite in addition, with respect to other sheet material, also heavier, and add and be prone to defect man-hour.
