Description
Technical field：
The present invention relates to Wood-plastic floor production technical field, and in particular to a kind of environmentally friendly, wear-resisting and sound-absorbing double-decker
Formula waterproof Wood-plastic floor.
Background technology：
At present, family is used on market, the floor that office occupancy is decorated generally to adopt wood floors or compoiste wood floor.Wood
The feel of quality plate is pleasant, but easily imbibition or drying distortions, often occurs contraction, expansion in use and becomes
Shape, warp, problems of crack, and need to expend a large amount of timber, the production cycle is longer, relatively costly.And compoiste wood floor master
If a kind of floor formed using the blended extruding of wood flour and binding agent and other additives, its surface color and polish is abundant, into
This is low, but there are problems that hygroscopic, and the subject matter on this floor is release formaldehyde, and serious harm human body is good for
Health, the feature of environmental protection are poor.
A kind of a kind of floor of the Wood-plastic floor technique productions such as to be utilization plastics extruded with sponge, has wood concurrently
The performance and feature of material and plastics, can replace the environmentally friendly hitech materials of timber and plastics.With excellent physical property, environmental protection
Property, appearance tactile impression is good, and the secondary workability with timber, by routine work mode, can be processed into various facilities and system
Product.General Wood-plastic floor includes four-layer structure, is from top to bottom followed successively by wearing layer, decorative layer, substrate layer and balance layer, needs
This four-layer structure is processed respectively, then is combined together by adhesive or pressing process.There is life in this production technology
The characteristics of producing complicated link, more control technology point and larger Productive statistics cost, and it is chemical substance that adhesive is most, it is long
The phenomenon that chemical reaction occurs with other materials in use environment occurs when phase uses, generates volatility and human body is had
Harmful material, so as to threaten health.
The content of the invention：
The technical problem to be solved be provide that a kind of production process is simple, that input cost is low is environmentally friendly, resistance to
The double-layer structural waterproof Wood-plastic floor of mill and sound-absorbing.
The technical problem to be solved is realized using following technical scheme：
A kind of environmentally friendly, wear-resisting and sound-absorbing double-layer structural waterproof Wood-plastic floor, including substrate layer and decorative layer, the base

12-15 parts, glycerol 18-20 parts.
The production method of the powder of straw is first to wash harvested straw three times, and then dry in the sun is less than to moisture
10%, Jing pulverizers are crushed, are sieved after roguing, and the powder for taking 40 mesh soaks 5-8h in 5% dilute hydrochloric acid solution, filter, finally
Jing oven dryings to moisture can be used less than 5%.
The straw is in rice straw, wheat stalk, corn straw, soybean stalk, broomcorn straw, Caulis Sacchari sinensis straw
One or more.
The preparation method of the modified bamboo powder is first bamboo powder to be soaked into 3-5h in 3-5% dilute nitric acid solutions, then at ultrasound
Supersound process 15-20min under frequency 22kHz, power 50-100W, then stirs lower addition equivalent sodium polyacrylate, is warming up to
75-80 DEG C reaction 30-60min, reaction terminate after filter, filter cake wash three times, most after Jing oven dryings be less than to moisture
5% can use.
The production method of environmentally friendly, wear-resisting and sound-absorbing the double-layer structural waterproof Wood-plastic floor comprises the following steps：
(1) amino resins, polyvinyl alcohol and ethanol are added in high-speed mixer, is warming up to 110-120 DEG C of insulation mixing
15-20min, adds chlorinated paraffin and triethanolamine after then natural cooling is cooled to 30-40 DEG C, continue to mix 5-10min, then
Material is added in ball mill, granularity is milled to less than 50 μm, coating liquid is obtained final product；
(2) first powder of straw is scattered in glycerol, adds animi resin, be warming up to 120-125 DEG C of insulation reaction 1-2h,
Reaction stands cooling after terminating, and obtains final product material I；
